We introduce a method of urban road network evaluation based on RS and GIS. This method evaluates urban road
network in a real-time, accurate and rapid way. According to scientificity and testability, road network evaluation
indicator system is established with the support of RS and GIS; the current data of urban road network is collected with
Erdas; the urban road data are digitized and organized with powerful MapInfo; Geodatabase of ArcGIS is adopted for
urban road database, and the relevant data is processed in order to extract the information required by road network
evaluation indicator system. The results of urban road network evaluation of a tourist city show that the method can
provide scientific evidence and information support for planning and construction of urban road network.
