Strathclyde Integrated Transport Model
The Strathclyde Integrated Transport Model (SITM) is a multi-modal transport model which covers the main road and public transport network in West Central Scotland. SITM was developed on behalf of Strathclyde Partnership for Transport (SPT). The coverage of the model is illustrated below.
In addition to utilising survey data to develop the transport model, SITM uses land-use and demographic forecast data from the Strathclyde Integrated Transport and Land Use Model (SITLUM) to develop the travel matrices. The base planning data is supplied through LATIS to ensure compatibility. The SITM contains road and public transport models and demand model processes, providing a forecasting methodology to predict changes in travel demand and transport costs over time.
The model is based on the SATURN suite for modelling the road network and the Cube TRIPS suite for the public transport network. The calibrated base for SITM reflects traffic and travel conditions in a 2007 Base Year. It can provide traffic forecasts on all main routes on the public transport network throughout the SPT area for a twenty year forecast period.
