Scottish Trip End Program
The Scottish Trip End Program (STEP) is a software application that has been developed by Transport Scotland to enable the derivation of population, employment, households by car ownership, trip ends and growth factors based on data from the National Transport, Demand and Land Use Models.
In producing forecasts based on the National Transport models, STEP has an advantage over similar tools as it incorporates 'Scotland specific' data. STEP also includes a better representation of base year trip ends as they have been calibrated to reflect observed data across Scotland during the development of the National Models.
STEP has been prepared for transport planning purposes. Specific uses could include informing on policy decisions and obtaining indicators on predicted changes in transport use over time.
It should be noted that forecasts such as those prepared by Transport and Land Use models are always subject to uncertainty. For guidance on how to manage uncertainty in transport forecasts, please see WebTAG Unit 3.15.5: Uncertainty in Forecasting.
