【摘要】 区别于现有基于道路交通系统(人-车-路)的风险分析理论,以驾驶员的认知和决策为核心,从事故发生概率、事故严重度、驾驶员风险认知水平、驾驶员控制能力,以及交通信息不对称度5个方面提出了驾驶行为决策风险的多维结构,分别给出了各风险因素的量化表达方法及其对应的风险度函数,并构建了综合风险度评价模型。以某公路弯道前后不同车型的驾驶行为决策为实例进行了分析,结果表明:驾驶行为决策是由多方面因素共同决定的,不同车型的综合安全风险度由高到低依次为大型货车、大型客车、小型货车和小型客车。更多还原

【Abstract】 A multi-dimensional structural model of risk on the driving behavior decision-making was proposed considering 5 aspects of factor including the accident probability,the accident severity,the risk cognition level of driver,the control capability of driver,and the traffic information asymmetry.In this structural model,the driver cognition and decision-making were taken as the core in order to distinguish the model from the existing risk analysis theory of the traffic safety based on the road traffic system(pedestrian-vehicle-road system).The quantitative expression of each risk factor and its corresponding risk level function were given respectively,and an integrated evaluation model was proposed for the safety risk level.A case study of driver behavior decision-making with different vehicle types before and after a bending section of highway was analyzed.The results show that the driving behavior decision-making depends on many factors,the integrated safety levels of 4 different vehicle types in order from serious to alleviatory are: heavy truck,big bus,light truck,and passenger car.更多还原
