About model
Transport Model for Scotland (TMfS) is a multi-modal transport demand and assignment model with an interactive Land Use model. The model currently covers 95% of the population of Scotland and all of the principal urban centres except Inverness. The modelled area covers all Trunk Roads and a large proportion of non Trunk principal roads.
The model is the next generation of the Central Scotland Transport Model (CSTM) series, with significant enhancements in data sources and model structure. It enables to:
- provide robust traffic forecasts on all Trunk Roads within the model area over a twenty year horizon;
- undertake traffic, economic and land-use assessments of proposed major inter-urban road schemes for Stages 1 (corridor assessment) and 2 (route option assessment) of the roads design process, as specified in the Design Manual for Roads and Bridges;
- test the effects of 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.
