Then, the roadtraffic accident reconstruction and simulation system is developed. This system is able to input the traffic accident scene information and simulate the traffic accident whole process.
The research integrates the prediction of traffic noise into the geography informationsystem, and designs and develops the urban roadtraffic noise prediction system which is based on the GIS.
To utilize real-time trafficinformation, increase the road network utilization and reduce the traffic jam, a kind of intelligent traffic system RTIC is presented.
