Details of Transport models and costs: FOI release

Information request and response under the Freedom of Information (Scotland) Act 2002.

Information requested


1. Who is the contact point within the Highways and Transportation team for transport modelling?

2. Please provide high level details of your existing strategic transport model/s.

3. When was your transport model/s last updated?

4. Which organisation (e.g. Consultancy firm) developed your existing transport model/s?

5. Which software does your existing model/s use? (e.g. Saturn, Visum)

6. How much did your existing model/s cost to develop?

7. What are your proposed plans (e.g. Procurement) to update your current transport model/s?




1. Paul Junik is Head of Transport Forecasts & Infrastructure Planning he is the contact person for modelling enquiries. We also have a mailbox for queries:

2. Transport Scotland have the following strategic transport models. It should be noted that some strategic models are being updated and some are currently being developed.

Transport Model for Scotland (TMfS14) - The TMfS14 is a National Transport Model that has been developed with a base year of 2014 to appraise national transport and planning policy along with strategic land-use and transport interventions. It provides a source of current and forecast national/strategic travel demand and associated demographic information. It has a number of forecast years including 2017 / 22 / 27 / 32 and 2037.
TMfS 14 runs in conjunction with Transport and Economic Land-use Model of Scotland (TELMoS) to provide future year forecasts.

Sestran Regional Model (SRM12) - The SEStran Regional Model (SRM) is a multi-modal transport model which covers the main road and public transport network in the South & East of Scotland. Geographically, the model covers an area that extends from the Firth of Tay to the Scottish Borders and from the East of Edinburgh to Stirling.

Strathclyde Regional Transport Model (SRTM14) - The Strathclyde Regional Transport Model (SRTM) is a multi-modal transport model which covers the main road and public transport network in West Central Scotland. It has a base year of 2014. SRTM was developed jointly with Strathclyde Partnership for Transport (SPT).

Tay Cities Regional Transport Model (TCRTM) - Tactran, Transport Scotland and the Tay Cities Local Authorities, are in the process of developing a regional model that covers the Tay Cities region (Angus, Dundee City, Perth & Kinross and North East Fife). Model development is expected to be completed this year.

Moray Firth Transport Model (MFTM) - The Moray Firth Transport Model (MFTM) is a multi-modal transport model and covers the main road and public transport network of the Inner Moray Firth area around Inverness. The MFTM contains road and public transport assignment models and demand model processes which provide a forecasting methodology to predict changes in travel demand and transport costs over time.

Further information on the models can be found at the below link:


3. TMfS14 is currently in the progress of being updated to TMfS18
TELMoS14 is being updated to TELMoS 18 in parallel with development of TMfS18
SRM12 was last updated in 2014
SRTM14 developed in 2017, its future forecasts are currently being updated;
TCRTM – Tay City Regional Transport Model development commenced in summer 2018 and is scheduled to be completed towards the end of 2019.
MFTM – Model built in 2009, however incremental updates have been undertaken on regular basis.

4. The following consultants are currently employed by Transport Scotland in developing its suite of transport models:
AECOM and Peter Brett Associates; and


5. TMfS14 was developed using CUBE voyager;
TELMoS 14 was developed using DELTA software;
SRM12 was developed using CUBE voyager and Saturn;
SRTM14 was developed using CUBE voyager and Saturn;
TCRTM is being developed using Cube voyager and Saturn; and
MFTM was developed using PTV VISUM..


6. Transport Scotland spends between approximately £500,000 - £600,000 per annum on model development. This excludes the cost of data collection which varies between each model under development.


7. Transport Scotland has a Land use and Transport Integrations in Scotland (LATIS) Call-Off Framework, which helps procure the services for the development, maintenance and application of national and regional transport models and the national land use model. The current framework is approximately 2 years into the 3 year contract period.
Transport Scotland plans are to continue to develop and maintain its suite of transport models through the LATIS framework, in order to ensure that these are available for use in support of project and policy development work by Transport Scotland.
