Traffic Information Management and Promulgating System Based on GIS

Traffic information is difficult to manage because of the characteristic of the huge amount of data, space, timeliness, and difficulties to describe. It is inconvenient for the traffic managers and travelers to understand and access the traffic information only depending on the form of promulgating by text or picture. So, the Geographic Information Systems (GIS) is introduced in the traffic management and promulgating system because of the traffic information urgently need by the current information society. The framework of the overall structure, main functions, database design, and system design in traffic information management and promulgating system based on GIS are discussed. The system can be convenient and efficient to extract and display the spatial information and attribute information of various sections of the road or traffic facilities. As well as through processing and analyzing traffic status information and traffic accident information, the road traffic incidents are to be early detected, early identified, early decided and early promulgate. So this system can be convenient for travelers and traffic managers to make decision.
