| Abstract: | ITS Common Information Platforms(CIP) have the requirements to distribute traffic geographical information in large area.Based on the design of ITS CIP web system in Guangzhou,the article analyzed the characteristics of traffic information distribution and studied the methods to apply WebGIS in traffic field.According to the differences of the external and internal information distribution,the article designed the logical structure of the system,with thin client mode and thick client mode respectively.And the physical structure took the distributed sever group technology to share the system load,and system security was properly designed. |
