1 INTRODUCTION
1.1 Purpose of Report 1.1.1 AECOM was commissioned in April 2017 by Highways England under the Collaborative Delivery Framework (Consultancy) 2016-2017 Annex D, to undertake PCF Stage 3 and 4 works associated with the A428 Black Cat to Caxton Gibbet improvements scheme. This includes the provision of transportation, environmental and other services associated with the delivery of the A428 Black Cat to Caxton Gibbet scheme through preliminary design and statutory procedures and powers. 1.1.2 AECOM is developing a new ‘Stage 3’ traffic model (referred to as the Stage 3 A428 Black Cat to Caxton Gibbet strategic model) to assist in the traffic modelling and assessment of the scheme in association with delivery of the relevant Project Control Framework (PCF) Products through Stage Gate Assessment Reviews (SGAR) 3 and 4. 1.1.3 This Transport Data Package examines the data used to derive existing flows and vehicular trends. The primary use for this data will be to calibrate and validate the new 2015 Base Year Traffic Model, based upon existing data where available and additional data where required. 1.1.4 The purpose of this Transport Data Package (TDP) is to encapsulate all of the data gathered to support the transport analyses required to underpin the ongoing modelling and assessment work of the proposed scheme. The TDP should: • Demonstrate that the data collected is sufficient in scope, accuracy and representativeness that it can be used to support the following analysis; and • Summarise the strengths and weaknesses of the base data from which the analysis will be undertaken. 1.1.5 Following the Appraisal Specification Report (ASR), the data packages required to develop the modelling and assessment tools have been agreed on an ongoing basis with Highways England’s Transport Planning Group (TPG) to establish what evidence is required and what form this evidence should take. Highways England’s own guidance provides the guiding quality criteria for the TDP which must: • Comply with the relevant guidance, specifically the Highways England Appraisal Manual, as well as other guidance such as WebTAG where appropriate and agreed with TPG; • Be appropriate to the scope of the scheme, reflecting the scale of impacts of both transportation and environmental effects but, where the gathered data is to be utilised in future stages, then address the requirements of these subsequent stages where it is cost effective to do so; • Be proportionate to the requirements of the stage of the project; • Given constraints of time and budget, be as unbiased and representative samples of the required statistical populations as possible; and

• Be produced in accordance with any specific requirements of Highways England on a case by case basis.
1.2 Scheme Description 1.2.1 The purpose of the Scheme is to address the problems of congestion, poor journey time reliability and poor resilience against incidents between the Black Cat and Caxton Gibbet roundabouts. The Scheme seeks to address these problems through construction of a new 10 mile (16km) dual 2-lane carriageway from the Black Cat roundabout to Caxton Gibbet roundabout, to be known as the A421 (hereafter referred to as the ‘new dual carriageway’), and in addition approximately 1.8 miles (3km) of tie-in works shown in schematic form in Figure 1-1 below. Figure 1-1: The Scheme
1.2.2 The Scheme includes the following components: a. A new three-level grade separated junction at Black Cat roundabout, with the A1 at the lower level, the new dual carriageway on the upper level and a roundabout between the two at approximately existing ground level. In addition to slip roads a new free flowing link between the A421 eastbound carriageway and the A1 northbound carriageway will also be provided. b. A new grade separated all movements junction will be constructed to the east of the existing Cambridge Road roundabout to provide access to the new dual carriageway and maintain access to the existing A428. c. At the Caxton Gibbet roundabout, a new grade separated all movements junction will be constructed, incorporating the existing roundabout on the south side of the new dual carriageway and a new roundabout on the north side. The new dual carriageway will then tie-in to the existing A428 dual carriageway to the east of the new Caxton Gibbet junction.

d. In the vicinity of the new Black Cat junction, direct access onto the A1 from some local side roads and private premises will be closed for safety reasons. A new local road will provide an alternative route. The existing Roxton Road bridge will be demolished and replaced with a new structure to the west to accommodate the realigned A421. e. New crossings will be constructed to enable the new dual carriageway to cross the River Great Ouse, East Coast Main Line railway, Barford Road, the B1046/Potton Road, Toseland Road and the existing A428 at Eltisley. f. The existing A428 between St Neots and Caxton Gibbet will be de-trunked and retained for local traffic and public transport with maintenance responsibility transferred to the local highway authorities. g. An alternative access will be provided to side roads at Chawston, Wyboston and Eltisley. h. There will be safer routes for walkers, cyclists, and horse riders.

2 TRANSPORT MODELLING REQUIREMENTS
2.1 Introduction 2.1.1 The approach to traffic modelling was identified and defined in the PCF Stage 3 ASR (Appraisal Specification Report) which explained that while a strategic model had been developed at Stage 2, a new Stage 3 model was required because of the need to: • Extend the geographical scope as this had become wider than at the start of Stage 2 with the need to consider both the A1 East of England Study and the Oxford to Cambridge Expressway and so the South East Regional Traffic Model (SERTM) offered a better platform for strategic routing; • Incorporate more data including turning and classified counts to strengthen calibration/validation for example in and around St Neots; • Provide a more robust set of matrices, both for longer distance trips using SERTM and shorter distance trips using synthesis; and • Improve the assurance rating from Red/Amber for PCF Stage 3 (Preliminary Design), Stage 4 (Statutory Procedures) and beyond. 2.1.2 The model is called the Stage 3 Black Cat to Caxton Gibbet strategic traffic model, hereafter referred to as the Stage 3 Model. The previous Stage 2 model is referred to as the Stage 2 Model. 2.1.3 Following the ASR, the data packages required to develop the Stage 3 Model have been agreed on an ongoing basis with Highways England’s Transport Planning Group (TPG) to establish what evidence is required and what form this evidence should take. TPGs own guidance provides the guiding quality criteria for the Data Package which must: • Comply with the relevant guidance, specifically the Highways England Appraisal Manual, as well as other guidance such as WebTAG where appropriate and agreed with TPG; • Be appropriate to the scope of the scheme, reflecting the scale of impacts of both transportation and environmental effects but, where the gathered data is to be utilised in future stages, then address the requirements of these subsequent stages where it is cost effective to do so; • Be proportionate to the requirements of the stage of the project; • Given constraints of time and budget, be as unbiased and representative samples of the required statistical populations as possible; and • Be produced in accordance with any specific requirements of Highways England on a case by case basis. 2.1.4 The data underpinning the earlier Stage 2 Model was reviewed and used where possible though the supporting data to develop the Stage 3 Model needed to be strengthened and cover a wider area and to improve the analytical assurance rating.

2.2 Extent of Model and Detailed Model Area 2.2.1 An initial step in defining the scope of the model in terms of more detailed modelling and therefore where the data collection needs to be more focussed is the likely area of influence test. 2.2.2 The wide geographical extent of the South East Regional Traffic Model (SERTM) meant that the area of influence of the scheme could be tested by coding the scheme into SERTM and run for a forecast year. This test guided the modelling approach and the area where more detail was required in terms of the demand data and zones and network coverage – known as the Area of Detailed Modelling (AoDM). 2.2.3 The AoDM is shown in Figure 2-1 along with the proposed screenlines (SLs) and cordons, accepting that these may change to some degree during the course of calibration / validation. The model structure and location of screenlines and cordons drove the data requirement based around the availability of existing data and therefore the need for new data. 2.2.4 The screenlines are depicted in more detail in Appendix A along with a reference number where each road is crossed and where data was required. The site reference number is then referred to in the relevant section of this report which describes existing and newly collected data.
2.3 Model Time Periods 2.3.1 An average weekday hour within each of three time periods will be modelled in the Stage 3 Model as follows: • AM Peak: 07:00 to 10:00 • Inter Peak: 10:00 to 16:00 • PM Peak: 16:00 to 19:00 2.3.2 Any reference to any of these three periods therefore refers to the hours defined above.
2.4 Vehicle Classifications 2.4.1 Vehicle type classifications were used in accordance with Department for Transport, National Road Traffic Census, Vehicle Classification Guidance 2018 and the ‘COst Benefit Analysis’ (COBA) classifications, as identified below: • Cars; • LGV: Light goods vehicles; up to 3.5 tonnes gross vehicle weight; • OGV1: Other goods vehicles, greater than 3.5 tonnes, up to 3 axles; • OGV2: Other goods vehicles, greater than 3.5 tonnes, 4 or more axles and all articulated goods vehicles; and • PSV: Public Service Vehicles (buses and coaches).

3.2 Black Cat to Caxton Gibbet Stage 2 Model 3.2.1 A significant number of Automatic Traffic Counts (ATCs) were undertaken in April/May 2016 for the calibration and validation of the Stage 2 Model. 3.2.2 ATCs were undertaken continuously (24 hours) over a two-week period. The differing periods were due to the presence of road works scheduled in the vicinity of some counts that could have impacted the flow of traffic through some sites. Each site monitored traffic flows in both directions and categorised vehicle types and vehicle speeds.

A428 Black Cat to Caxton Gibbet improvements Appendix A: Traffic Data Collection Report
3.2.3 One hundred and thirty nine sites were originally identified for the placement of ATCs. Six sites were subsequently identified that were unsuitable for the placement of pneumatic tube ATCs because of safety concerns due to the volume of high speed traffic and these were surveyed using radar instead. Seventy four of these sites were used for the Stage 3 Model and these (all referred to as ATCs) are identified in Table 3-2 which also provides the AECOM model screenline reference number that can be cross referenced to the screenline maps in Appendix A. 3.2.4 A summary of the model input data by time period is provided in Appendix B (Parts 1, 2 and 3 for the AM peak, Inter Peak and PM peak respectively). These are taken from Excel spreadsheets which are available in digital form as is the raw survey data provided on PCF stage handover by Jacobs. The data presented in Appendix B may have undergone some cleaning and factoring between raw data provision and model input. 3.2.5 It should be noted that the excel spreadsheets in Appendix B include data for all sites irrespective of the source (existing or newly collected). These data are also available in digital form as well as the raw data provided by the survey company. 3.2.6 Basic data checks were undertaken on the survey data including SATURN plots to show the proportional directionality of traffic flows. This indicated that four ATC sites (site reference numbers 15, 16, 17 and 69) to the west of Cambridge appeared to have been mislabelled by the survey company so that their directions were transposed and incorporated into the Stage 2 Model calibration / validation. For initial processing for the Stage 3 modelling these site directions were therefore reversed and follow up surveys were carried out at a later date to confirm that this was the correct course of action.

3.2.7 A limited number of Manual Classified Link Counts (MCLCs) and Manual Classified Turning Counts (MCTCs) were also available from the Stage 2 Model. Where appropriate, these were used for validation / calibration and to help provide vehicle classification proportions for WebTRIS ATC site locations. The site details are provided in Table 3-3. Vehicle classifications were as identified in section 2.5.

3.3 WebTRIS 3.3.1 Highways England WebTRIS data (http://webtris.highwaysengland.co.uk/) was accessed to provide long term ATC site data in June 2015. Twelve sites were identified and data for the period 1st June to 30th June 2015 was taken for most sites. Due to lack of complete data availability during this period at the two sites on screenline 10, data was taken for the period 23rd to 30th June 2015. 3.3.2 These sites were used directly for calibration / validation purposes for the screenlines shown in Table 3-4. The A428 sites were also used for the purpose of calculating annualisation factors. The summary traffic flows by time period are provided in Appendix B while the geographical location of the sites by screenline is shown in Appendix A.

3.3.3 Data from a number of WebTRIS sites was also used to calculate factors to enable the conversion of survey data to the common base of June 2015. This was done on the basis of road sections so that more local variation could be taken into account in the factors derived. The sites used in this way are identified in Table 3-5 below alongside the road sections for which they were used.

3.4 Journey Time Data Introduction 3.4.1 Journey time data collected in June 2015 was used to validate the modelled journey times across a number of defined routes and also to check that competing ‘rat runs’ were modelled accurately and realistically.
Planning Inspectorate Scheme Ref: TR010044 16 Application Document Ref: TR010044/APP/7.10
A428 Black Cat to Caxton Gibbet improvements Appendix A: Traffic Data Collection Report
3.4.2 Trafficmaster (TM) data obtained from the Department for Transport (DfT) was used to provide average journey times for each of the three time periods modelled. TM data is obtained from various types of vehicles including fleet vehicles, LGVs, HGVs, buses, using in-vehicle GPS devices and trackers. It takes the form of average observed journey times by Ordnance Survey MasterMap Integrated Transport Network (ITN) links, which can be added together to define the required route times in total and by way point and both by time period. 3.4.3 The base model year is 2015 and so the majority of the TM data required was collected during the development of the Stage 2 Model, even though that was defined as a 2016 base year. A relatively small additional set of data was however needed to extend the coverage of journey times to include routes from Cambridge across to Rugby covering the local authority areas of Leicestershire and Northamptonshire. These data formed the core database for comparing measured with model journey times. Data Cleaning 3.4.4 The Trafficmaster data were aggregated to give a mean journey time and standard deviation of journey times for each ITN link, in each modelled time period, across all weekdays (excluding Bank Holidays) during the data collection period. The mean and standard deviation values were used to establish a maximum threshold for observations, which were defined as two standard deviations above or below the mean. 3.4.5 Observations (i.e. the group of observations relating to the day selection, time period and ITN link in question) with mean journey times above the maximum threshold were identified as ‘outliers’ and those observations were excluded from the journey time data set. The resulting ‘cleaned’ data set was then used to recalculate each ITN link’s mean value and its variance for each time period. The mean journey time (post-cleaning) was used to calculate each period’s mean journey time of the whole journey time route. Journey Time Routes for Model Validation 3.4.6 Ten strategic routes were identified for the purpose of journey time validation and these are summarised in Table 3-6 and depicted in Figure 3-1.

Summary of Journey Time Data 3.4.9 The journey time graphs (Appendix C.) provided a visual indicator as to whether there were any anomalies and were also useful in gauging the relationship between speed and time period. There were no notable patterns indicating which time period experienced the quickest/ slowest speeds as they differed across routes, as well as by direction.

3.4.10 Overall, the analysis of the journey time graphs demonstrated that the data is suitable to be used in the validation of the modelled journey times. Additional Journey Time Routes Check ‘Rat-Running’ 3.4.11 As well as the ten strategic key routes identified for model validation, a further set of seven competing routes were identified on more local roads where traffic flows could be affected by the scheme improvement and these were generally east to west within the corridor of the scheme. 3.4.12 These competing routes, which could be considered as alternative routes especially during peak times when more delays are experienced on the main route, are listed in Table 3-8 below and shown in Figure 3-2. A number of the competing routes use the same sections on the same roads and so for clarity, these are displayed in separate diagrams in Figure 3-2 i.e. routes 15, 16 and 17.

3.5 Roadside Interview Data 3.5.1 Roadside interview (RSI) data collected in 2009 was available for a cordon around St Neots. This survey data contains trip purpose and postcode of origin and destination. These RSI data are relatively old, but in the context of the study, and taking into account the phasing of significant housing and transport infrastructure, the data were deemed to be of value to assist in matrix building, given the significance and close proximity of St Neots to the A428. 3.5.2 The RSI survey in St Neots intercepted traffic in the inbound direction. Interviews from the RSI site in the centre of St Neots (R8 on the map) were not used as this site does not form part of a cordon (sites R4 and R5 cover most of the site 8 traffic). 3.5.3 Expansion factors were calculated using more recent traffic counts (April 2016) on the St Neots RSI cordon to re-expand the RSI data.

4 SPECIFICATION AND EXECUTION OF SURVEYS
4.1 Project Requirements 4.1.1 The new Stage 3 Model required additional surveys be undertaken to supplement and extend the existing data, particularly where there were gaps in the screenlines / cordons and where more information was needed on vehicle classification data and turning movements. The extra data was therefore needed both in terms of geographical coverage and refining the evidence of traffic conditions. Certain survey types are best suited for specific purposes within modelling and also for particular locations. The relative merits, limitations and costs of the output of the surveys were considered as part of the survey specifications. 4.1.2 Seasonal and longer term data trends were needed to ensure all data could be adjusted to the same period as the base model. Generally the existing data from the WebTRIS sites was used to factor the data. 4.1.3 Automatic traffic counts (ATC) generally provide a two-week period of continuous data that enables the evaluation of individual weekday patterns and peak periods. They are also used to determine the general traffic flow and if a more detailed single day’s count is representative. They have limitations particularly in relation to the classification of vehicle types. 4.1.4 Manual Classified Counts (MCC) provide a more detailed set of information regarding volumes by vehicle class but are more resource intensive, and therefore expensive. 4.1.5 Automatic Number Plate Recognition (ANPR) surveys provide information about the routing of traffic within an area between the camera sites. They are dependent upon specialised equipment. 4.1.6 Further details on each survey type can be found within the relevant sections that follow. 4.1.7 There were further survey requirements for data to be used in other areas of the project; for example VISSIM modelling of separate junctions, highway design considerations and the use of alternative routes (rat-runs) within the area. These were all included within the surveys undertaken. 4.1.8 Some surveys were undertaken on more than a single occasion. This enabled the cross referencing and comparison of outputs to check for variability, both at the specific site and other locations. 4.1.9 Where possible the surveys were specified to cover more than a single requirement.
4.2 Selection of Locations for Surveys 4.2.1 A review of the locations of the existing data, particularly that collected for Stage 2, informed the selection of the sites for the Stage 3 surveys. 4.2.2 Counts were needed along the roads crossing the screenlines and cordons. These were identified in Appendix A. Volumetric classified count information was also captured at these locations.
Planning Inspectorate Scheme Ref: TR010044 25 Application Document Ref: TR010044/APP/7.10
A428 Black Cat to Caxton Gibbet improvements Appendix A: Traffic Data Collection Report
4.2.3 Within the study area there are a number of alternative east / west routes that are used to avoid delays at junctions along the main A428 during peak times. An objective of the scheme is therefore to transfer ‘rat-running’ traffic on to the A428 by increasing its capacity and so survey site coverage was also focused on these roads to ensure that the model was sufficiently accurate to capture these movements. 4.2.4 Similarly ANPR survey sites were positioned to provide a wide cordon around the junctions at Black Cat and Caxton Gibbet. The objective of the site selection was to better understand the movement of traffic through the corridor to assess the potential for re-routing once the scheme is built and to assist in developing and interpreting the model.
4.3 Traffic Survey Companies 4.3.1 The traffic survey and data collection tasks were commissioned by AECOM on behalf of Highways England and the majority were conducted by Intelligent Data Collection (IDC). The ANPR surveys and a small number of additional counts were conducted by TRACSIS.
4.4 Surveys Required 4.4.1 The surveys required were a mixture of ATCs, MCCs and an ANPR survey. 4.4.2 It was either unsafe or impractical to use ATC tubes on higher speed roads and in certain locations. An alternative methodology was therefore adopted at these locations in the form of video cameras which recorded continuously over two weeks so that the traffic counts could be undertaken later, manually, from the videos. 4.4.3 The types of surveys and their locations are described in more detail in the following sections.
4.5 Dates of Surveys 4.5.1 Traffic surveys are generally carried out during periods when the flow of traffic can be considered ‘neutral’ when compared to the rest of the year. The months that are considered neutral, according to the government’s WebTAG Unit M1.2 are late March, April, May, June, September, October and November. In this case, the counts were undertaken towards end of June to mid July 2017 for the first phase of surveys and during September 2017 for the second phase. 4.5.2 Although the July period was not considered neutral, in discussion with Highways England’s TPG it was deemed acceptable following a review of traffic conditions on the A428 and demonstration that conditions in the earlier to mid part of July were not significantly different to June or other neutral periods. It was helpful in terms of the programme to survey in July 2017 ahead of the school summer holidays.

Paragraph 6.1.6 Table 6-2: Location of 6 MCC June 2018 Additional Manual Classified Counts 4.5.4 The equipment requirements for undertaking this number of surveys was significant and it was not possible to gain all permissions required from the Local Highway Authority within the initial time frame. Surveys were therefore staggered before and after the holiday period and certain sites repeated and paired to check for any seasonal variation. This is discussed further in section 5.3. 4.5.5 Further requirements also arose during the work which were not known at the start i.e.: • Weaving and other MCC surveys were required in September 2017 to support the ongoing development of the model; • The need to gather ANPR survey data in October 2017 to check routing through ‘rat-runs’; • Extra surveys in March and April 2018 were needed to check the directionality of the Stage 2 data where this appeared to be inconsistent when compared with other processed data; and • Surveys in June 2018 were needed to gather additional information regarding the vehicle compositions at key locations for which ATC traffic data had previously been collected. Video footage was also acquired at this time at key access locations on the A1 for use in design considerations rather than input to the strategic modelling.

4.6 Incidents 4.6.1 Over the course of the survey period, any observed incident on a particular link which may have affected the completeness or quality of the data surveyed was recorded by the survey company. Some of the incidents caused a small amount of data loss and in a few instances required data to be replaced and traffic re-counted. Other incidents may have affected the flow of traffic but did not compromise the quality of the data. 4.6.2 A detailed log of incidents is provided in Appendix D and summarised in Table 4-2 below: Table 4-2: Incidents Affecting Data Collection
Incident Type Number of reported occurrences Slow Traffic 1 Equipment issue 11 Fog 1 Camera Failure 34 Road Works 2 Data corrupted / lost 2 Bike race 1 Clock Change 2
4.6.3 Key observations from the incident log are summarised below: • Overall 54 sites over 52 different surveys had one or more recorded incidents that the survey company felt might impact on the data quality. • One record was made by the survey company of an incident caused by adverse weather conditions. This was fog during a morning collection which resulted in lower counts than expected. • There was one incident of a special event, a bike race, which resulted in a higher number of cyclists than expected at a single site. • There were two sites reported as having road works in place during the survey period. • All other reported issues related to equipment or camera failures. 4.6.4 For each issue the survey company recorded the time period during which data was impacted. The majority of the camera and equipment issues occurred during the night, so were not likely to impact on the data used for modelling. 4.6.5 AECOM staff were aware of some road closures on the A14 trunk road during this period, but otherwise there were no apparent exceptional events. 4.6.6 The data was subsequently processed to identify and, if necessary, remove any outliers from the data sets.

4.7 A14 Construction Impacts 4.7.1 Construction work was underway on the A14 Huntingdon to Cambridge route during the programme of surveys. The A14 traffic management in place during the survey period primarily comprised of reduced speed areas (40 mph) and narrow running lanes. Anecdotal reports suggested that journey times on the A14 increased due to the speed reductions and that journey times were more reliable. 4.7.2 Undertaking the surveys for this project whilst the A14 Huntingdon to Cambridge works were underway was not ideal. However waiting for the construction to finish would have imposed unacceptable delays to the modelling work in relation to the overall programme. 4.7.3 A review of survey site data was undertaken and several on the A14 indicated congested traffic on particular survey days. The sites that were impacted were sites 45, 46 and 100 and occurred on the following dates 15/09 (Fri), 18/09 (Mon), 22/09 (Fri) and 25/09 (Mon). This data was therefore excluded when calculating flows to use within the modelling.
4.8 Clarifications and Corrections 4.8.1 As the data was collected, processed and supplied to AECOM a number of checks and reviews were undertaken. This was to ensure that the data taken forward appeared sensible, matched expectations and was clearly and consistently documented. 4.8.2 Initial checks were made on the incoming information. These were designed to provide a quick review of what was provided to highlight any missing data. After this further checks included cross referencing between relevant data, and spot checks of the counts provided by the survey company. The assessments that were made were different for each survey type, therefore the specifics of the checks are detailed within each survey section. 4.8.3 These checks led to a number of issues being identified ranging from simple clarifications e.g. to map the precise site location, to the recoding and supply of a large volume of vehicle classified count data. 4.8.4 The data summaries provided in Appendix B are based upon final checked and processed data.
4.9 Report Section Revisions 4.9.1 A table is provided at the end of each section of this report which details any revisions made from one report issue to the next.

5 OBSERVED AUTOMATIC TRAFFIC COUNTS
5.1 Introduction 5.1.1 ATCs are undertaken using detectors placed across the road surface, usually for a period of two weeks. 5.1.2 WebTAG Unit M1.2 states that the accuracy of an ATC, is of the order of ± 5% at the 95% confidence level. This guidance also states that this ATC confidence interval relates to counters with tube vehicle detectors, and suggests that it may be possible to achieve greater levels of accuracy with inductive loops. 5.1.3 Counts were recorded in 15 minute intervals throughout the 24 hour survey periods. The ATCs were placed at the locations as detailed in Table 5-1. The survey dates within Table 5-1 include some partial days. Data was collected during phases 1, 2 and 5 of the survey programme as listed in Table 4-1. The surveys used directly in the validation / calibration process have the associated screenline reference (SL Ref) number listed in the table, otherwise the reference is left blank.

5.2 Observed Link Count Surveys 5.2.1 At certain locations it was not appropriate to place ATC counters on the link for safety reasons. Therefore a number of road links were surveyed using a video method, similar to that used for the MCC counts. Counts were undertaken for 14 days at these sites. 5.2.2 These were recorded in 15 minute intervals throughout the survey periods and their locations are listed in Table 5-2.

5.3 Seasonal Variation 5.3.1 Ten repeat surveys were undertaken in September 2017 at the same location as the July 2017 surveys to check for variability in the counts and to provide reassurance that the two sets of data could, more widely, be combined in developing the base year traffic model. These sites were generally higher flow sites in a range of locations within the Area of Detailed Modelling and are identified Table 5-3.

5.3.2 Comparisons were made of the data at these sites by total traffic flow, vehicle proportions (notably the percentage HGV) and directionality across 15 minute periods throughout the day and for rolling hourly totals. 5.3.3 The detailed plots for the rolling hourly totals are shown in Appendix E, alongside further breakdowns by vehicle type. These show that the data was generally consistent at each site between the two monthly periods. There was no indication that there was a consistent difference between the survey periods that needed to be taken into account in the data used for modelling purposes.
5.4 ATC Data Checks and Cleaning 5.4.1 The count data set was checked for anomalies and the main discrepancies discovered from the checking process are summarised below. 5.4.2 ATC and MCC volumetric data were compared at the same locations on the same days. The purpose was to inform whether the WebTAG recommended use of specific data for traffic model calibration and validation purposes (i.e. averaged ATC data for total flows, split into classifications using MCC data) is robust in this application across all counts. 5.4.3 Two important issues were identified regarding ATC data: the accuracy of the vehicle classification, and the accuracy of the ATC volumetric data. To allow for the former issue, the assumption in line with WebTAG is that the MCC data will be used in preference to the ATC classification as it should provide more accurate vehicle proportions. The latter issue is more significant as the ATC data are used to obtain longer term ‘average’ weekday hourly flow data. It is therefore important that these volumetric data can be relied upon. 5.4.4 The absolute and percentage differences between the ATC and MCC at 12 hour (07:00-19:00) and hourly levels were calculated to determine whether the ATC volumes were consistent with the corresponding MCCs. Where counts were found to have zero flows in any counted hour, these hours were removed from the dataset. 5.4.5 For comparison purposes the analysis used the following criteria to define differences: • < -5%; • Between -5% and +5%; • > 5%. 5.4.6 Overall, 80 percent of sites showed good agreement between the ATC and MCC data, both as hourly profiles and over the total 12-hour period that incorporates all the modelled hours. However, there was a slight tendency within these counts for the ATC to be lower than the MCC.

5.4.7 For twelve of the sites there were considered to be significant differences between the ATC and MCC counts, with absolute variations above 5%. These sites were investigated and, for some, reasons for differences were provided in discussion with IDC. This resulted in problematic data being removed from the sites and another comparison being made. This resulted in nine of the sites being judged to be consistent for use, sometimes by excluding some periods of data. 5.4.8 The issue at one remaining site was due to the re-location of the survey to a more congested location. The ATCs were undertaken using pneumatic tube equipment and it is known that these can be less reliable when located on the approach to junctions. The nature of the axle counts using tubes means that performance can be compromised under various situations such as queuing traffic, slow moving traffic and misreading of multi-axle vehicles. At this site an alternative MCLC was available for use. 5.4.9 One of the sites had been surveyed in both July 2017 and September 2017 and the differences in September were only just above the threshold. As the ATC counts were comparable during the two survey periods this was used for volume data and the average of the MCC used for proportions. 5.4.10 The final site with a significant percentage difference was based on a very low total flow. The absolute difference was therefore small. This site was ultimately not used within the modelling.
5.5 ATC Variation 5.5.1 Within the ATC data there can be substantial variation. This can be representative of the general day to day fluctuations. For this reason multiple days of ATC data were collected in order to evaluate how changeable traffic volumes are at each site and in turn what variation can be expected on an ‘average’ day. 5.5.2 The initial checks included a visual evaluation of the summary graphs provided by the survey company of the variation analysis. An example from ATC Site 42 for one direction is shown in Figure 5-1. This indicated that the data for the Wednesday in Week 5 (the short purple bar) should be checked. Also, the Wednesday in Week 3 (the longer red bar) should be reviewed. During the working week traffic was generally lower on a Monday, higher on a Friday and similar on Tuesdays, Wednesdays and Thursdays.

5.5.3 The graphs provided by the survey company provided whole day totals. A more comprehensive evaluation of the data variability was undertaken with the three time periods (AM, PM and IP) evaluated separately. 5.5.4 Any time period on an individual day with recorded traffic flow outside of two standard deviations from the mean (as calculated from the ATC data) were flagged as outliers. Approximately 4% of sites were initially flagged as outliers. These sites and their data were then reviewed in more detail and if necessary excluded from calculations.
5.6 Manual Classified Counts 5.6.1 Over thirty sites were considered as not being suitable for the placing of pneumatic tubes. These sites are the same as those identified in Table 5-2: Video Link Count Locations. In these cases a 14 day manual classified count was undertaken. These were reviewed separately from the ATCs as they were not likely to have the same issues in terms of the vehicle recording equipment. 5.6.2 An initial visual inspection was undertaken for data completeness within the provided information. In addition some re-count spot checks of the data were made. As there was only a single method of data collection it was not possible to cross reference the traffic volumes to an alternative count. 5.6.3 A summary of the results of the surveys by time period is included in Appendix B.

6 OBSERVED MANUAL CLASSIFIED SURVEYS
6.1 Manual Classified Link Counts 6.1.1 MCCs are generally collected from a video survey whereby a camera is located in a fixed location with full view of the link or junction concerned. 6.1.2 The number and classification of vehicles passing this fixed location are then transcribed from the video. MCC surveys were undertaken on one neutral weekday during the ATC period from 07:00 to 19:00. 6.1.3 WebTAG Unit M1.2 states that, at the 95% confidence limit, there is an accuracy of ± 10% for total traffic volumes.. The errors arising from MCCs are both total flow volumes and the vehicle categorisation. It is suggested that the categories of light goods vehicles and 2-axle rigid lorries can be a particular problem and that some accuracies are of the order ± 37%. 6.1.4 The counts were recorded in 15-minute intervals throughout the 12-hour survey period. For the purpose of the traffic model and presentation the results are aggregated into hourly flows. 6.1.5 The MCCs were placed at locations as detailed in Table 6-1, these were the same locations as the ATCs which were identified in Table 5-1 in section 5. Sites listed in Table 5-2 were already manually counted as they were locations where an ATC was not used.

6.2 Manual Classified Turning Counts 6.2.1 MCTC surveys were undertaken on two neutral weekdays in September 2017 from 07:00 to 19:00 at the major roundabouts and junctions. This was phase number 2 of the survey programme as listed in Table 4-1. Site 103 was re-surveyed in November 2017. The other locations had a MCTC survey undertaken for a single neutral weekday in September 2017. 6.2.2 A few turning counts were used in the calculation of screenline vehicle splits, most were used for junction analysis. The MCTCs were placed at the locations listed in Table 6-3.

6.3.2 Some minor issues were initially queried with the survey company. The majority of these related to typographical mistakes or lack of clarity within site location diagrams that had been provided. Given the large number of surveys more detailed checks were undertaken once the data availability had been confirmed. 6.3.3 In locations where there was a corresponding ATC the MCC was compared to the ATC volumes. This focussed on the total volumes of vehicles. In this case the MCC could be confirmed by reviewing the video footage, especially regarding the vehicle classifications. The accuracy of the ATC was dependent upon the installation. Therefore, in this case, it was assumed that the manual count was likely to be more accurate than the ATC counter. 6.3.4 The detailed checks revealed some issues in terms of the direction of flow and vehicle classifications as follows: • The directions were reversed at a number of WebTRIS sites and information regarding this was fed back to Highways England; and • A review of the vehicle video footage indicated that the classification of vehicle classes had not been applied consistently by the survey company. As a result of this a large number of sites were returned to the survey company for recounting (this is described further below). Vehicle Classification 6.3.5 Guidance for use in classifying vehicles is contained within the document entitled Department for Transport, National Road Traffic Census, Vehicle Classification Guidance 2018. This also accords with the COBA classification. 6.3.6 The DfT guidance does however make clear that the distinction between LGV and OGV1 is based upon carrying capacity and that some vehicles with a carrying capacity up to 3.5 tonnes gross vehicle weight can have twin tyre rear axles (see attached example).
6.3.7 The number of twin tyre rear axles has sometimes been used as a convenient way of distinguishing between LGV and OGV1. This is not correct according to the above guidelines. All new survey data was therefore classified according to DfT’s guidance, however all existing data could not be checked in this way and may have been classified according to the number of twin rear tyre axles. 6.3.8 The issue was identified when inconsistencies were apparent following detailed checks of the returned videos at adjacent sites. As a consequence the survey company were able to pinpoint the specific sites where vehicles had been mis- classified in this way and were able to re-classify the data correctly applying the DfT guidelines. 6.3.9 The percentage difference between the re-coded data and the original data is shown in Appendix F by vehicle category and by each site affected. Not surprisingly the
Planning Inspectorate Scheme Ref: TR010044 44 Application Document Ref: TR010044/APP/7.10
A428 Black Cat to Caxton Gibbet improvements Appendix A: Traffic Data Collection Report
LGV and OGV1 were most significantly impacted by the re-classification. The original classification counts had overestimated OGV1 by around 3.5% in terms of total traffic and underestimated LGVs by the same order of magnitude. This was because some vehicles with twin rear tyre axles were re-classified as LGVs. However this varied on a site by site basis depending on vehicle mix and those with a difference of 5% or more are grey shaded in the table. 6.3.10 The vehicle classes of bus, motorcycle and cycle are not included in the tables in Appendix F as they generally form very low proportions of the total traffic. The average figure is not weighted by the vehicle counts. 6.3.11 The summary of the original and re-issued data vehicle proportions along with a comparison of the changes can be found in Appendix F.

7 AUTOMATIC NUMBER PLATE RECOGNITION
7.1 Introduction 7.1.1 An Automatic Number Plate Recognition (ANPR) survey was undertaken covering a comprehensive number of entry and exit points across the study area. The purpose of the survey was to enable checks to be made of the key movements at for example junctions, the identification of possible east/ west rat running movements that were being used in preference to the main A428 / A421 route and more generally for both strategic and operational (microsimulation) modelling. 7.1.2 The survey was carried out on 18th October 2017. This was phase number 4 of the survey programme as listed in Table 4-1. The survey sites where vehicle registration plates were captured (both directions) were positioned at the locations shown in Figure 7-1 and defined by OSGRs and road location in Table 7-1.

7.1.3 Vehicle registration plate details were automatically recorded using high specification video cameras and matched at each location the vehicle passed along with the time stamp. Vehicle classification details were obtained from the vehicle registration number. 7.1.4 The ANPR survey was also supported by continuous Manual Classified Link Count (MCLC) surveys at each entry/exit point in order to estimate the capture rate for inbound and outbound vehicles. ANPR can occasionally mis-number plates if obscured or unreadable and as such the capture rate falls below 100%. Overall a capture rate of 92% and a matched rate of 69% was reported for all movements. 7.1.5 The individual capture rates by site, one for each direction, are identified in Table 7-2. This shows that most were on or above 90% though at two sites (22 and 23) the capture rate was greater than 100% (both directions). In order to investigate this, data for the day in 15 minute time bands was requested from the survey company for these sites. This showed that there were periods during which link counts were missing but that the ANPR cameras were still collecting data. As a result of this the 15 minute link counts and plate counts were requested and reviewed for all sites. 7.1.6 Match rates are derived for a 12 hour period (7am to 7pm) and by setting the maximum journey time to 90 minutes between the first and the last match.

7.2 Factored Data 7.2.1 Based on the matched data and the capture rates at the various sites the data can be factored up to represent the total traffic. This process requires both the origin and destination match and capture rates. An initial summary, by time period, for the total traffic for each origin and destination are given in Table 7-3,

8 OTHER SURVEY DATA 8.1.1 While the majority of the surveys were undertaken to provide input into the strategic traffic modelling process some additional data was collected for other purposes: • A weaving survey on the A1 to the north of Black Cat was undertaken on Tuesday 26 September 2017. This was to understand the levels of weaving in the area and the lane usage. The results are shown in Figure 8-1; and • 15 minor access locations on the A1 were surveyed (listed in Table 8-1 and shown in Figure 8-2) using video cameras and traffic movements transcribed from the videos. The recorded footage covered a week, and movements on a single day between 26/07/18 and 28/07/18 were counted for each site. This was to provide information on traffic using each access for design purposes and also to provide a visual presentation to assess the impacts on safety. 8.1.2 This data collection formed phase number 3 of the survey programme as listed in Table 4-1.

9 SUMMARY AND CONCLUSIONS
9.1 Summary 9.1.1 AECOM was commissioned by Highways England under the Collaborative Delivery Framework (Consultancy) 2016-2017 Annex D, to undertake PCF Stage 3 and 4 works associated with the A428 Black Cat to Caxton Gibbet improvements scheme. 9.1.2 As part of this work, a new ‘Stage 3’ traffic model is being developed to assist in the assessment of the scheme in association with delivery of the relevant Project Control Framework (PCF) Products through Stage Gate Assessment Review (SGAR) 3. 9.1.3 The geographical extent of the new traffic model along with the initial location of model validation / calibration screenlines was informed by carrying out a Likely Region of Impact test using the South East Regional Traffic Model. A gap analysis was then undertaken to establish the availability of existing data, including data used for the Stage 2 Model and the requirement for further surveys to develop the Stage 3 Base Year Model. 9.1.4 Existing data was utilised in the form of Automatic Traffic Counts (ATCs) and a small number of Manual Classified Counts (MCCs) undertaken for the Stage 2 Model in April 2016 as well as interrogation of Highways England’s WebTRIS database. These were supplemented by a major programme of ATC, MCC and MCLCs surveys at 108 locations (72 ATCs/MCLCs and 36 MCCs) as well as a programme of Automatic Number Plate Registration (ANPR) surveys to provide information on routeing through the model area and MCTCs used in junction analysis and in some cases to determine vehicle splits. 9.1.5 Due to initial programme constraints, the surveys were started at the earliest possible date at the end of June 2017 running through to mid-July 2017 with the remaining surveys carried out in September 2017. Any seasonal variation was checked and these periods were deemed suitable in terms of reflecting other neutral months. The variation of traffic flows and vehicle composition was also checked between July and September by repeat surveying at several sites. 9.1.6 ATC counts were undertaken for a minimum two weeks of 24-hour periods between 28th June 2017 and 19th July 2017 and between the 10th September 2017 and 26th September 2017 for the September surveys. 9.1.7 MCC surveys were undertaken for a 24-hour period over two neutral weekdays. 9.1.8 ANPR surveys were undertaken for a 12-hour period between 7am and 7pm on 18th October 2017. 9.1.9 Any major incidents were reported by the survey company. Any significant data losses were rectified by gathering more days of data at the specific site affected. 9.1.10 Other ad-hoc surveys were also undertaken including vehicle turning counts after September 2017 to provide further information to inform the ongoing development of the scheme design.

9.1.11 Ten journey time routes were identified for the purpose of validating the traffic model and Trafficmaster data, provided by DfT, was used to identify journey time profiles for these in each of the model time periods. In addition, competing ‘rat run’ routes were identified to validate the model where alternative route choices existed.
9.2 Conclusions 9.2.1 It can be concluded, based upon observations and the subsequent checks carried out on the count and journey time data, that the existing data and data collected through the major programme of surveys undertaken as part of this Stage 3 study provide sufficient data for representative days and are suitable for use in further modelling analyses.
