Abstract

Transit planners recognize that spatially varying demands affect the assessment of transit system alternatives. However, they do not yet possess the tools necessary to properly determine the effects of the variation on estimates of user benefits. An extended measure of user benefits that is consistent with net consumer surplus from classical economic theory is presented. Also presented is the structure of a travel forecasting model that can show the effects of activity allocation, trip distribution, and route choice on net consumer surplus. Individual components of the model have already been extensively tested in practice and are described in the academic literature, but the transit ridership properties of the model, as a whole, have not been established. The model is capable of finding a joint equilibrium solution between activity allocation, mode split, trip distribution, and traffic assignment. Tests of the model on real networks indicate that spatial redistribution of activities resulting from a transit service improvement can be large enough to determine whether the improvement should be implemented.
