Method of Traffic Safety Evaluation of Newly Designed Highway Based on Driving Simulation

Implementing traffic safety evaluation is an efficient way to improve road safety, especially for newly designed roadways. In this paper, a new method of road safety evaluation, based on the vehicle driving simulator, was studied. In this study, a large number of experiments are implemented. Combined with the data of vehicle speed and vehicle lateral offset collected from the driving simulator during the process of simulation, drivers' psychological and physiological data are collected and analyzed. Unsafe road sections and the main factors were studied from the statistical data. The data analysis results indicated that typical data can express traffic safety risk. The research results could advise the alignment design and ancillary equipment design for newly designed roads and improve traffic safety in advance.
