Preferential and Managed Lane Signs and General Information Signs
2009 Edition Page 253 CHAPTER 2G. PREFERENTIAL AND MANAGED LANE SIGNS Section 2G.01 Scope Support: 01 Preferential lanes are lanes designated for special traffic uses such as high-occupancy vehicles (HOVs), light rail, buses, taxis, or bicycles. Preferential lane treatments might be as simple as restricting a turning lane to a certain class of vehicles during peak periods, or as sophisticated as providing a separate roadway system within a highway corridor for certain vehicles. 02 Preferential lanes might be barrier-separated (on a separate alignment or physically separated from the other travel lanes by a barrier or median), buffer-separated (separated from the adjacent general-purpose lanes only by a narrow buffer area created with longitudinal pavement markings), or contiguous (separated from the adjacent general-purpose lanes only by a lane line). Preferential lanes might allow continuous access with the adjacent general-purpose lanes or restrict access only to designated locations. Preferential lanes might be operated in a constant direction or operated as reversible lanes. Some reversible preferential lanes on a divided highway might be operated counter-flow to the direction of traffic on the immediately adjacent general-purpose lanes. 03 Preferential lanes might be operated on a 24-hour basis, for extended periods of the day, during peak travel periods only, during special events, or during other activities. 04 Open-road tolling lanes and toll plaza lanes that segregate traffic based on payment method are not considered preferential lanes. Chapter 2F contains information regarding signing of open-road tolling lanes and toll plaza lanes. 05 Managed lanes typically restrict access with the adjacent general-purpose lanes to designated locations only. -

Safety code for new drivers 119 1 Introduction This Highway Code applies to Gibraltar. However it also focuses on Traffic Signs and Road Situations outside Gibraltar, that as a driver you will come across most often. The most vulnerable road users are pedestrians, particularly children, older or disabled people, cyclists, motorcyclists and horse riders. It is important that all road users are aware of The Code and are considerate towards each other. This applies to pedestrians as much as to drivers and riders. Many of the rules in the Code are legal requirements, and if you disobey these rules you are committing a criminal offence. You may be fined, or be disqualified from driving. In the most serious cases you may be sent to prison. Such rules are identified by the use of the words ‘MUST/ MUST NOT’. -
Impact Assessment
Title: Impact Assessment (IA) Raising the speed limit for HGVs >7.5T on dual carriageway roads IA No: DfT00280 Date: 23/09/2014 Lead department or agency: Stage: Final Department for Transport Source of intervention: Domestic Other departments or agencies: Type of measure: Primary legislation None Contact for enquiries: [email protected] Summary: Intervention and Options RPC Opinion: EANCB Validated Cost of Preferred (or more likely) Option Total Net Present Business Net Net cost to business per In scope of One-In, Measure qualifies as Value Present Value year (EANCB on 2009 prices) Two-Out? £0m £0m £0m Yes Zero net cost What is the problem under consideration? Why is government intervention necessary? On dual carriageways the speed limit for HGVs>7.5T is 50 mph. The average actual speed at which these HGVs travel in free flow conditions (when they are not held up by other traffic or obstructions such as junctions, hills or bends) is about 53 mph (excludes rigid 2 axle HGVs)1. More than 80% of HGVs exceed 50 mph in free-flow conditions. The limit is out of date and systematically ignored by professional HGV drivers. The proposal is to raise the speed limit on dual carriageway roads for these vehicles to 60mph, which would better reflect the capabilities of modern HGVs. Government intervention is necessary because speed is regulated by government, through speed limits, in order to balance the private benefits of speed of travel with the social costs and risks (such as related to safety) of high speeds. What are the policy objectives and the intended effects? The intention is to modernise the speed limit, improve compliance, make the limit more credible and legitimise the behaviour of professional drivers. -
2B-1 Application of Regulatory Signs Regulatory
6. REGULATORY SIGNS 2B-1 Application of Regulatory Signs Regulatory signs inform highway users of traffic laws or regulations and indicate the applicability of legal requirements that would not oth- erwise be apparent. These signs shall be erected wherever needed to fulfill this purpose, but unnecessary mandates should be avoided. The laws of many States specify that certain regulations are enforceable only when made known by official signs. Some regulatory signs are related to operational controls but do not impose any obligations or prohibitions. For example, signs giving ad- vance notice of or marking the end of a restricted zone are included in the regulatory group. Regulatory signs normally shall be erected at those locations where regulations apply. The sign message shall clearly indicate the require- ments imposed by the regulation and shall be easily visible and legible to the vehicle operator. 2B-2 Classification of Regulatory Signs Regulatory signs are classified in the following groups: 1. Right-of-way series: (a) STOP sign (sec. 2B-4 to 6) (b) YIELD sign (sec. 2B-7 to 9) 2. Speed series (sec. 2B-10 to 14) 3. Movement series: (a) Turning (see. 2B-15 to 19) (b) Alignment (sec. 2B-20 to 25) (c) Exclusion (see. 2B-26 to 28) (d) One Way (sec. 2B-29 to 30) 4. Parking series (see. 2B-31 to 34) 5. Pedestrian series (see. 2B-35 to 36) 6. Miscellaneous series (sec. 2B-37 to 44) 2B-3 Design of Regulatory Signs Regulatory signs are rectangular, with the longer dimension vertical, and have black legend on a white background, except for those signs whose standards specify otherwise. -

Roundabouts Applying the 'System'
Roundabouts Applying the 'System' to Roundabouts Let us suppose that you are on a dual carriageway approaching a roundabout (400m away). You are currently in the left lane and you intend to turn right at the roundabout. Information: - Take - You see the roundabout and its triangular warning signs in the distance. There are no vehicles between you and the roundabout but you see vehicles on the roundabout. Mirror check. There are two vehicles behind, both in the left lane. - Use - You know that you have to change to the right lane and that you will need to signal to change lane and then to signal continuously on the approach and through the roundabout (the standard Highway Code procedure for turning right at a roundabout)- Give - After checking your mirrors you signal right to the vehicles behind. Position: The right signal remains on for a few seconds and then gradually you move to the right hand lane (Information-Use/Give). When the manoeuver is complete you cancel the signal. After a few more seconds the right signal is re-applied to confirm to the drivers behind that you intend to turn right at the roundabout. Information: The speed and position of the vehicles behind are monitored as you approach the roundabout. An assessment is made of the movement of vehicles on the roundabout and those approaching it from the right and left. You look over the roundabout to see, if possible, vehicles approaching it from the opposite direction (Information-Take). Speed: As you approach the roundabout you begin to brake and lose speed smoothly and progressively (Information-Give). -

St Albans City Archive Catalogues - Transcription
St Albans City Archive Catalogues - Transcription Introduction The St Albans City Archive is one of the main sources of primary material for anyone researching the history of the city. However, understanding what is in the archive is daunting as the key finding aid, the catalogue produced by William Le Hardy in the 1940s, does not match the standard of modern catalogues. Improvements are underway. The City Archive has been held at Hertfordshire Archives & Local Studies (HALS) in Hertford since the 1990s. HALS are currently engaged in an extensive project to improve access to its catalogues via the internet. The City Archive is part of this project but it is likely to be several years before the fully revised catalogue is available on-line. In light of this and with HALS’ agreement, the St Albans & Hertfordshire Architectural & Archaeological Society (SAHAAS) has opted to publish the following transcription of Le Hardy’s catalogue together with relevant material from the ‘Interim’ catalogue. (The latter represents a further deposit by St Albans City Council in the 1990s). For the benefit of SAHAAS members, most of whom live closer to St Albans than to Hertford, we have noted on the transcript the following additional information: 1. Microfilm numbers: much of the pre-1830 archive has been microfilmed. Copies of these films are held in the Local Studies filing cabinets at St Albans Central Library. (See column marked Microfilm/Book) 2. A transcription of the St Albans Borough Quarter Sessions Rolls, 1784-1820, was published by the Hertfordshire Record Society (HRS) in 1991. (See column marked Microfilm/Book) Finally, some of the items catalogued by Le Hardy were not subsequently deposited by the City Council. -
GIS Data Hub Data Collection Specification - Part 2

For example, a) Type C (straight / right turn shared arrow): one arrow only, hence only one point (x1, y1) required. V2.7 Page 9 Licensing & Data Management Section (LDM) GIS Data Collection Specification b) Types G (left converging arrow) & H (right converging arrow): two arrows, hence two points (x1, y1) and (x2, y2) are required. 2) The bearing should correspond with the bearing of each individual road. For example, if the bearing of the road is 97 degrees, then the bearing of arrow markings A is 97 degrees and the bearing of arrow markings B is 277 degrees respectively. -
Traffic and Road Sign Recognition
Traffic and Road Sign Recognition Hasan Fleyeh This thesis is submitted in fulfilment of the requirements of Napier University for the degree of Doctor of Philosophy July 2008 Abstract This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm. Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%. -
TA 79/99 Amendment No 1 3
Chapter 3 Volume 5 Section 1 Determination of Urban Road Capacity Part 3 TA 79/99 Amendment No 1 3. DETERMINATION OF URBAN ROAD CAPACITY 3.1 Table 1 sets out the types of Urban Roads and the features that distinguish between them and affect their traffic capacity. Tables 2 & 3 give the flow capacity for each road type described in Table 1. 3.2 Table 4 gives the adjustments when the proportion of heavy vehicles in a one way flow exceeds 15%. A heavy vehicle is defined in this context as OGV1, OGV2 or Buses and Coaches as given in the COBA Manual (DMRB 13.1 Part 4, Chapter 8). 3.3 The flows for road type UM in Table 2 apply to urban motorways where junctions are closely spaced giving weaving lengths of less than 1 kilometre. Urban motorways with layout and junction spacing similar to rural motorways can carry higher flows and TA46/97 “Traffic Flow Ranges for Use in the Assessment of New Rural Roads” will be more applicable. 3.4 Flows for single carriageways are based upon a 60/40 directional split in the flow. The one-way flows shown in Table 2 represent the busiest flow 60% figure. 3.5 The capacities shown apply to gradients of up to 5-6%. Special consideration should be made for steeper gradients, which would reduce capacity. 3.6 On-road parking reduces the effective road width and disrupts flow, e.g. where parking restrictions are not applied on road type UAP2 the flows are likely to be similar to UAP3 where unrestricted parking applies, see Table 1, Similarly effective parking restrictions can lead to higher flows.
