Stated Diversion of Car Commuters to Public Transit: A Case Study in Jinan

Abstract

Comparing to trips by bus, a person's trip by car generally needs more road resources for the same distance. If some of car owners give up car use and choose buses to complete their trips, traffic jams may be alleviated largely. When those factors affecting trip generation are changed, car owners may change their choice of cars and public transit. The purpose of this paper is to identify those traffic conditions that may make car owners change their trip modes, from cars to public transit. For this, the authors designed a questionnaire by orthogonal table design and collected 1079 filled forms. Based on the valid forms the authors established a MNL model. The resulting model, consistent with the surveyed data or common sense, shows that the improvement in bus service and the increase in parking fee and fuel cost may force car owners to turn from car use to bus ride. This model may be used for other purposes.
