Abstract

The PRISM model system is a variable demand multi-modal transport model developed for the West Midlands region by RAND Europe and Mott MacDonald. It consists of detailed network models covering the highway and public transport (PT) systems, which are linked to a disaggregate demand model. The network (supply) and demand models are run iteratively. The demand model reflects a number of traveller responses in a number of interacting modules, including car ownership, PT travel pass ownership, tour frequency, destination choice, mode choice and time of day choice. All of these models, except for the car ownership model and the trip frequency model for business and non-home-based travel, were estimated from local data. A brief description of the model responses and data used for estimation of these models is provided in the summary below. Because the mode and destination models have been estimated from local data, the outputs provide evidence on appropriate model structure and illustrative model parameter values. More detail is therefore provided on these models in this report. (Author/publisher)
