In order to evaluate road safety in design stage, virtual simulation tests are proposed. The system includes the modeling of virtual road based on Creator, the development of vehicle dynamics model and 3D model, the development of real-time simulation software based on Vega and road safety evaluation model. Through the visual simulation tests, the vehicle speed inducement effect of the road can be obtained at the design stage. This system was applied to Xi’an-Hanzhong freeway and Baoshan-Longling freeway projects, the results show that this system can be used to guide the road alignment design and improving design of traffic facility, and to provide foundation for road safety audit.
