Design and Implementation of an Optimum Multi-Path Inquiry System with Graphic Show on City Rail Transit

摘要

A method and its related techniques to realize an optimum multi-path inquiry system with graphic show on city rail transit have been described in details in this paper, by combining of the search algorithm for optimal multi-path and the method to determine reachable optimal multi-path with night last trains of city rail transit network. Its software architecture design, data organization mode for all of the optimum paths, method to draw multiple lines of city rail transit network in concurrence, drawing and redisplay control, and application of GDI+ drawing functions are included. Finally, the illustration about its application effect has been presented too.
