Abstract:First analysis the style of shared-path routing based on rail network and the passenger flow characteristics, then focuses on the design of shared-path routing diagram structure, the using method of the train set of linking or of non-linking, the reasonable match of train interval, the optimization of first and last train timetable and the coordination of interchanger station, the effective utilization of depot and the effect of delay propagation. At last, the computing procedure and method of timetable designing was discussed.
