Transport Model for Scotland - TMfS:07

In 2008, a new, strategic Transport Model for Scotland was developed, with a base year of 2007.

TMfS:07 represents a step change in the quality of the national model with a number of technical enhancements and an improved basis in observed data.

TMfS:07 and TELMoS:07, the linked national land use model, will form the standard release version of the model for the foreseeable future, offering a more detailed and robust analysis than previous versions.

TMfS:07 is more strategic than its predecessor, TMfS:05a. Key changes include:

• inclusion of the Highlands and Islands into the main demand model
• a reduction in the number of zones
• a more consistent zoning system with equal importance given to both rural and urban areas with the zone system based on Census data zones
• where possible all rail stations were in a zone on their own
• representation of urban and interurban bus supply
• a two stage public transport route choice procedure

This new approach provides a more proportionate distribution of zones between urban and rural areas and allows for quicker run times.

Further enhancements to TMfS:07 include a better representation of the road and public transport network (georectified network), High Occupancy Vehicle (HOV) modelling, Park and Ride as a separate mode in the demand model, and enhancements to TELMoS.

The revised model has also benefited from the inclusion of a significant volume of new data including:

• 2007-based approved Local Authority planning data
• Integrated Transport Network distance data
• 2005-2007 Scottish Road Traffic Database count data
• the National Rail Travel Survey
• Census Travel-to-Work data
• inter-urban bus passenger origin-destination data
• bus-based Park and Ride passenger origin-destination data
• additional Roadside Interviews, including on port-access roads
