【摘要】：随着公路里程和汽车保有量的增长,驾驶员的数量和交通事故也呈上升趋势。通过对道路交通事故的致因分析可知驾驶员的因素是导致事故发生的主要原因,并且已有研究表明,危险感知是与交通事故密切相关的。因此,识别出驾驶员群体中危险感知能力相对较弱的个体,并进行针对性的培训,提高他们的危险感知能力,是减少交通事故的重要途径之一。结合已有研究成果和大量交通事故现场资料,通过对危险感知过程的分析,分别从驾驶“感知”、“决策”、“操控”以及“车辆运行”四个方面构建了驾驶员危险感知评价指标体系与评价方法。在西南交通大学犀浦校区仿真平台的基础上,通过模拟驾驶技术和眼动技术的结合,以及动态再现交通危险场景的方式,完成了对驾驶员危险感知测评仿真系统的设计与实现,使其可直接通过驾驶模拟器和眼动仪对驾驶员在交通危险场景中的各项指标数据进行采集提取。与此同时,实现了对驾驶员危险感知评估软件的初步设计开发,使其可对通过测评系统提取的各项指标原始数据进行统计和运算,并提供用户交互图形界面,在论文提出的评价方法的基础上,得到驾驶员的综合测评分数,实现对驾驶员危险感知能力的定量化评价。最后通过对测评结果的比较排序,形成相对优劣程度的对比,从而识别出驾驶员群体中危险感知能力相对较弱的个体,为职业驾驶员的选拔和运输企业安全管理对策的制定提供依据和支撑。
[Abstract]:With the increase of road mileage and vehicle ownership, the number of drivers and traffic accidents are on the rise. And it has been shown that risk perception is closely related to traffic accident. Therefore, we can identify the individuals with relatively weak risk perception ability in the driver group, and carry out targeted training to improve their risk perception ability. It is one of the important ways to reduce traffic accidents. Based on the existing research results and a large number of traffic accident site data, through the analysis of hazard perception process, The evaluation index system and evaluation method of driver's risk perception are constructed from four aspects of driving perception, decision making, control and vehicle operation respectively. Based on the simulation platform of Xiupu Campus of Southwest Jiaotong University, the evaluation index system and evaluation method of driver's risk perception are constructed. Through the combination of simulated driving technology and eye movement technology, and the way of dynamically reproducing the traffic hazard scene, the design and implementation of the simulation system for evaluating the driver's risk perception is completed. Through driving simulator and eye movement instrument, it can collect and extract every index data of driver in traffic danger scene. At the same time, the preliminary design and development of driver's risk perception assessment software are realized. So that it can carry on statistics and operation to the original data of each index extracted by the evaluation system, and provide the user interactive graphical interface. On the basis of the evaluation method proposed in the paper, the comprehensive evaluation score of the driver can be obtained. Finally, through the comparison and ranking of the evaluation results, the relative advantages and disadvantages of the drivers are compared, so as to identify the relatively weak individual in the driver group. It provides the basis and support for the selection of professional drivers and the formulation of safety management countermeasures for transportation enterprises.
