According .to the characteristics of Flex technology system, this paper analyzes the architecture of WebGIS based on Flex and describes the advantages in the design of WebGIS. It also offers the design of WebGIS system for the service on traffic management by combining ArcGIS API for Flex from ESRI Company. Through the realizations of the functions of data publication, map displays, statistics charts and so on, it explains the design process of WebGIS based on Flex. Therefore, it proves that the usage of Flex can im- prove the efficiency of the interactivities of clients of WebGIS. But the ArcGIS API for Flex development kit still has some shortcom- ings, such as the lack of front - end communication performance and the weakness of query function and so on.
