DEVELOPMENT AND APPLICATION OF A MODEL TO EVALUATE TRANSPORTATION IMPROVEMENTS IN URBAN CORRIDORS

This paper introduces the linear program model developed at the University of Pennsylvania for evaluating transportation improvements in a high-travel-demand urban corridor. Variables included in the linear program are discussed, and the linear objective function and the constraint equations of the model are outlined. Application to a radial travel corridor in Chicago, Illinois, illustrates the capability of the model; an analysis is made of existing corridor bus service and several corridor capital investments to improve that service. In the analysis of existing bus service, several alternatives to the existing price structure of bus transportation in the corridor were studied; the major result was an evaluation of the shift in mode choice caused by the different pricing schemes and the effects of a change in patronage on bus operating and capital costs. For the study of alternative capital investments, the corridor model computes the patronage attracted by the improvements and adjusts operating and bus capital costs of bus lines serving the corridor.
