Abstract:

It is one of vitally important factors that waiting time can directly impact on the attraction of bus systems for commuting trip. Rational division of the waiting time service level is helpful to improve performance service quality of bus systems. By passenger interview, psychological change process waiting for the bus is obtained. Based on the passenger psychological characteristics, the passenger waiting time is divided into four levels of service, such as Ⅰ、Ⅱ、Ⅲ and Ⅳ. The interval between each level of service is determined by developing membership grade and according to the maximum principal of membership grade. Based on the stated preference survey, waiting time value models for each level of service are put up applying the disaggregate theory and passenger perceived waiting time is quantified with waiting time value according to passenger paying intention in order to discover the differences of the passenger perceived waiting time on the each level of service and variational regularities with income and the level of service. Results indicate that not only the perceived waiting time on the level of service Ⅱ, Ⅲ and Ⅳ is respectively 50%, near 300% and 540% up compared with level of serviceⅠ, but also on the level of service Ⅰ and Ⅳ the perceived waiting time by the various income communities is little differentiated, but on the contrary on the level of service Ⅱand Ⅲ. It may provide important scientific support with making performance service quality standards for passenger, optimizing operation dispatching scheme and promoting the attraction of bus systems.
