Abstract
The paper presented not only the difference of the marginal walking time by passenger, but also the derivation of the bus service determination model by passenger attributes. The marginal walking distance to bus stop is a basic parameter to estimate bus service coverage area in certain area. And the marginal walking distance could be transformed from the marginal walking time, which is the focus of this paper. The result of analysis revealed that the age and income of passenger are strongly related to the marginal walking time. The model suggested in this paper help for the planner to choose optimal alternative in planning or regulating the spacing of bus routes or bus stops in certain area,.
