The Study Of Drivers’ Hazard Perception Evaluation System

As the growth of the highway mileage and car ownership, the number of drivers and traffic accidents is also on the rise. Through the analysis of the cause of road traffic accidents, we know that the driver’s factor is the main cause of traffic accidents. Besides, studies have shown that risk perception is closely related to traffic accidents. Therefore, identifying the drivers of relatively poor risk awareness, providing targeted training and improving their risk perception is one of the most improtant ways to reduce the number of traffic accidents.Combined with the existing research results and a large number of traffic accident scene data, this pape has built the evaluation index system and evaluation methods of drivers’risk perception respectively from the process of driver’s perception,decisions, control and vehicle motion state through the analysis of risk perception process.On the basis of the simulation platform in Southwest Jiaotong University,combined with the driving simulation technology and eye movement technique, the driver’s risk perception evaluation simulation system was designed and completed through the way of dynamic reappearance of traffic risk scenarios,which can extract the drivers’evaluation index data in traffic risk scenario.At the same time, a software for driver’s risk perception evaluation is designed and developed to calculated the drivers’evaluation index data,which can provide interactive graphical user interface and get the driver’s comprehensive evaluation scores on the basis of the evaluation method, in order to realize the quantitative evaluation of driver’s risk perception. Finally, it can identify the poor ability of drivers by comparing the measurement results, in order to provide the basis and the support of professional driver selection and safety management countermeasures of transportation enterprise.
