Abstract
To solve the problem that traffic safety risks is difficult to identify and compare quantitatively for the new road or accident black spots, the virtual simulation tests (VST) system is put forward combined the numerical simulation. The driver module on vehicle speed control, the vehicle dynamic network solution module, traffic environment 3D model, traffic safety management and control module, human-vehicle-road virtual simulation module are presented. The VST is used to detect the safety risks of the Baoshan-Longling freeway of Yunnan province and to analyze the safety improvement project of the Xi'an-Hanzhong freeway of Shaanxi province. The results show that the VST is effective to identify the road safety hazardous and the potential accident incentives, which has important significance for improving the operation safety and traffic management of road.
