Abstract:Based on the urban transportation demand, this paper studied the dispatching problem of bus service frequency and bus size associated with urban transit to transport passengers. For the operation characteristics of dedicated line, optimization models of maximum passengers’ perception utility dispatching and average passengers’ perception utility dispatching were developed respectively with the algorithms provided. An application of the models to the case of K1 bus line in Jiangyin shows that the optimization models are practical and effective for reducing the cost of bus transit operation and improving the operating efficiency of bus transit system.
