GIS-based road traffic control information and traffic resources analysis system

Based on geographical information system (GIS), a system is developed to manage urban road traffic information with high efficiency and analyze road traffic resources visually. In the system road traffic control information is represented by graphic objects such as points, lines or regions in GIS, while the specifications of them are stored in the attribute table of the objects. Moreover, GU interfaces are developed to process, edit, query, display and print the information. Finally a road traffic resources analysis system based on road network and traffic control information associated with them is developed, and it gains the better efficiency in practice.
