The model
Transport Model for Scotland (TMfS) is a multi-modal transport demand and assignment model that incorporates an integrated Transport and Economic Land Use Model (TELMoS). The model contains an extensive dataset of both transport and land use data within Scotland and has a capability of forecasting the transport and land-use changes resulting from major infrastructure and/or policy initiatives.
The model is an important element of Transport Scotland’s toolkit to assist in transport scheme and policy appraisal. It was developed by MVA Consultancy with its land-use capability developed by David Simmonds Consultancy.
The model enables to:
- provide robust traffic forecasts on all Trunk Roads within the model area;
- undertake traffic, economic and land-use assessments of proposed major inter-urban road schemes for Stage 1 (corridor assessment) and Stage 2 (route option assessment) of the roads design process, as specified in the Design Manual for Roads and Bridges;
- test the effects and/or interaction between major inter-urban road and public transport schemes and major transport policy options such as: a) schemes to improve inter urban public transport; b) schemes or policies aimed at reducing congestion in accordance with the Road Traffic Reduction Act, National Targets Act and the Transport White Papers; and c) schemes which introduce road user charging (road tolls or congestion charging); and
- provide consistent information and a framework for local scheme models, as a basis for the development of Local and Regional Transport Strategies or with a view to testing potential strategies.
