Abstract:: To improve the practicability of mobility allowance shuttle transit and its systematical service capacity on the basis of trying to keep the characteristics of its operation mode, based on time utility analysis of MAST passenger, a model to improve service of aggregation points was proposed by further setting corresponding main demand of mechanization service area checkpoints except in control point. Evaluation models of passengers’ time utility based on aggregation points was set. Finally, the validity of the improved model was verified by simulation example combining quantitative and qualitative method. The results show that setting up aggregation points in rectangle zones can improve efficiency systematic utility of MAST. The “limitative origins & region-wide destination service mode has the biggest overall utility in rectangle service area under normal possibility of demand occurrence, showing high feasibility and applicability. Although the mode lowers the convenience of transport for passengers to some extent, it cuts down time for making much invalid spot stop and detour and avoids problems of detail location of demand spots and inadequate stop in some demand sport, meanwhile maintaining the disperstiveness of passengers’ destinations to retain its advantage of arriving directly.
