Abstract: Based on the methods and techniques of geographical information system (GIS) and traffic geographical information system (GIS-T), the main spatial (configuration) characteristics and geographical background information of a traffic network were analyzed from itself and its background factors and by combining an experiment on the related data for Chengdu City using MapInfo, and the method and technique of the analyses were discussed. The research and experiment show that the method of spatial analyses for traffic geographical information based on GIS has more advantages over the traditional analysis methods in time, effect, accuracy, and integration and so on.
