STUDY OF PARKING AND TRAFFIC DEMAND. 2 A TRAFFIC RESTRAINT ANALYSIS MODEL (TRAM)

This paper describes the development of a new Traffic Restraint Analysis Model (TRAM); the application in Bristol will be described in part 3 of this study. TRAM is designed to examine how policies for traffic restraint, especially parking controls, might affect traffic in an urban area. It represents such policies by changes in those 'supply' elements of transport provision, which influence travel costs. It represents demands by a set of matrices of movements between zones and treats home-based tours in considerable detail, in terms of available potential choices, but other trips have a much more limited treatment. Demand is modelled as a nested series of incremental logit models, handling various travel choices. Parking choice is applied only for the car mode, and modelled only if the destination is a designated parking zone. The representation of transport supply covers road travel, parking, bus travel, and rail travel. TRAM iterates between supply and demand until convergence is achieved. It requires the following data: (1) travel demand data; (2) transport supply data; (3) parking supply, pricing, and enforcement data; and (4) model coefficients. Finally, TRAM's calibration of parking, road journey times, and road link traffic flows, and TRAM's validation and acceptance tests are described.
