Title: A best path enquiry system based on road and transit combined network
Abstract: A new GIS-based searching system is developed to seamlessly integrate transit networks into road networks in GIS and calculate the optimal path in the combined network between the origin and the destination.In the system,virtual links instead of connectivity matrix play a vital role in connecting two networks,and all factors that affect the travel plan are stored in the attributes table of the integrated network so that data structure can be simplified.Because of the uniformity of its network topology,the standard shortest path searching algorithm can be embedded and utilized without any modification.In addition,different weights of travel impedance in the system can be set to satisfy the individual choices of travelers.Finally,a case based on MapInfo indicates that the system is able to improve the efficiency of searching.
