Abstract

A method is presented that was used to improve the bus network in Hefei, in Anhui Province, in the People's Republic of China. The method attempts to develop a better bus route network by examining the total passsenger disutilities (total passenger travel distance and total passenger transfers) and selects the one that results in the minimum passenger disutility. The model that was used was designed to develop a bus network that minimizes the total passenger distance or total passenger transfers in the service area. Assuming that the passenger demand is not sensitive to the changes in bus network configuration, this model computes the total passenger transfers for each alternative network and, by trial and error, determines the best one. The criteria can be expanded to include passenger travel time by considering different travel speed on the road network. These criteria can best be used in the situation in which most riders are captive and the passenger demand is inelastic to the service supply pattern.
