A central element of the Commission was to develop and deliver an enhanced 2007-based land-use and transport modelling system. MVA proposed a hierarchical modelling framework, with a single National Strategic Travel demand and Land Use Modelling framework as the upper tier, Regional Travel Demand Models as the mid-tier and detailed local models (eg microsimulation) as the lower tier. The National Modelling Framework has now been developed. It incorporates a number of technical enhancements and new and more robust data and will, in time, replace its predecessor, TMfS/TELMoS:05. On 6 November 2008, the TMfS Term Commission changed its name to Land-Use and Transport Integration in Scotland (LATIS). The service is provided by Transport Scotland and their supporting consultants and offers a wide range of support and technical advice. The LATIS service currently includes four distinct elements, as follows: a user engagement programme, consultations, discussions and advice on a range of transport and travel planning issues; the collection and provision of land-use planning data; the collection of transport data through the use of the Data Collection Contract; and a travel demand and land-use modelling suite. The TMfS:07 and TELMoS:07 models are designed to deliver the fourth of these elements. TMfS:07 & TELMoS:07 Model Reports This report describes the development of the TMfS:07 National Road Model and is one of a series of eight documents describing the construction, calibration and validation of the TMfS:07 and TELMoS:07 models, as shown below: TMfS:07 National Travel Demand Model 1.

TMfS:07 National Public Transport Model Development Report i 1 Introduction 1.1 Overview 1.1.1 The National Public Transport Model forms part of the overall 2007 TMfS model hierarchy (see diagram below). It is a strategic model which has been prepared with a level of detail commensurate with appraising national policy and strategic land-use and transport interventions and providing a key source of transport supply and demand data. 1.1.2 TMfS:07 will also form the starting point for the development of Sub-Area and Regional models; providing assistance in preparation of model structure, input to base year development and providing a source of forecast year travel demand. Demand Model National Public National Road Transport Model Model TELMoS – Transport, Economic & Land Use Model Figure 1.1 Simplified TMfS Model Hierarchy – National PT Model Interaction 1.1.3 The National Public Transport Model has been developed using the GIS-based software package ArcGIS and Citilabs CUBE Voyager software. 1.2 Structure of this Report 1.2.1 The structure of the remainder of this report is as follows: Chapter 2 describes the modelled time periods, user classes and modes; Chapter 3 provides information defining the operational characteristics of the public transport system; Chapter 4 describes the matrix development procedure and data sources used to create the Public Transport Assignment Matrices; and Chapter 5 summarises the conclusions & recommendations relating to the TMfS:07 Public Transport model. TMfS:07 National Public Transport Model Development Report 1.1 2 Model Dimensions 2.1 Model Dimensions 2.1.1 The relevant week-day time periods are: AM peak hour - 08:00-09:00; AM peak-period – 07:00-10:00; Inter peak – average hour between 10:00 and 16:00; PM peak hour - 17:00-18:00; and PM peak period (16:00-19:00). 2.1.2 The public transport assignment model reflects conditions in the AM Peak Hour, Average Inter-peak Hour and PM Peak Hour. 2.1.3 Peak hour demand data and observed count data has been derived from the three-hour peak period data through application of a peak period to peak hour factor. These factors have been obtained from analysis of the TMfS:07 bus occupancy count data and the National Rail Travel Survey (NRTS). The resulting factors were very similar for bus and rail and have therefore been combined into a single set of Public Transport Peak Hour factors. These factors are reported in Table 2.1. Table 2.1 Peak Hour Factors Time Period Bus NRTS Average PT Peak Period to Peak Hour (AM) 0.44 0.45 0.45 Inter-peak (average of 10:00-16:00) 1/6 1/6 1/6 Peak Period to Peak Hour (PM) 0.42 0.47 0.44 User Classes 2.1.4 There are three user classes in the model: ‘In work’ (IW), eg trips on employers business; ‘To/from work’ (TW), ie commuting trips between home and work; and ‘Non work’ (NW), ie all other journey purposes. 2.1.5 Demand matrices have been prepared for each user class, which are assigned separately to the public transport network in the model. TMfS:07 National Public Transport Model Development Report 2.1 2 Model Dimensions Modes 2.1.6 The MODE control statement defines the characteristics of the public transport modes used by the PT System. Six separate modes have been coded, namely: Urban Bus; Inter-urban bus; Rail; Underground; Ferry; and Tram (not used in the base year but included to permit the modelling of tram schemes in future year public transport networks). TMfS:07 National Public Transport Model Development Report 2.2 3 Public Transport Network 3.1 Introduction 3.1.1 This Chapter describes the development of the network and public transport supply. The TMfS:07 National Model has been developed in Cube Voyager. 3.2 Public Transport Network 3.2.1 TMfS:07 includes a single modelled network that is used by both the Public Transport assignment model and Road assignment model. This allows for easy and consistent transfer of changes in forecast road traffic delays. 3.2.2 The modeled transport network has been developed using a Geographic Information System (GIS), with files being directly input to CUBE Voyager software. The network is based on ITN MasterMap data to give better representation of actual road network (geo-rectification), which is particularly useful for environmental analysis of model outputs. 3.2.3 The modelled network includes the following elements: strategic road network; heavy rail/underground; ferry links; road, rail and ferry zone connectors; and walk connections between rail/underground/ferry ports and stations, and the road network.
