中文摘要: 在无信号控制公路平面交叉口,驾驶人自主决定通过交叉口的时机、路线和行驶速度,车辆的运行主要依赖于驾驶人的主观判断。因此,交通流是自组织的,在很大程度上取决于驾驶人的心理活动和驾驶行为,具有相当大的随机性和不确定性,非常容易诱发各种交通事故。本项目拟对上述交通流自组织现象进行系统研究:运用心理学研究无信号控制公路平面交叉口驾驶人的心理活动和驾驶行为,揭示交通流自组织的微观机理,建立车辆的物理运动模型;对车辆的物理运动模型进行系统综合,运用交通流理论构建宏观层面上的交通流模型;运用自组织理论解析交通流自组织的基本过程,研究交通流自组织中的协作与竞争,构建交通流自组织有序度的评价指标和评价方法,建立交通流自组织演变的预测模型。项目将建立无信号控制公路平面交叉口交通流自组织理论体系,增进对交通流自组织机理和演变规律的理解,提高对交通事故成因的认知水平,为交通规划、设计和管理的工程实践提供支撑。

英文摘要: At unsignalized at-grade highway intersections, drivers decide the start time, route and driving speed when crossing the intersection all by themselves. The operation of vehicles mainly depends upon the subjective judgement of drivers. Therefore, traffic flow is self-organizing and depends upon the psychological activities and behaviors of drivers greatly. It is full of randomness and uncertainty and is easy to lead to all kinds of traffic accidents. The project aims to study the self-organizing phenomenon of traffic flows discussed above: study the psychological activities and driving behavior of drivers at unsignalized at-grade highway intersections, by applying psychology, disclose the microscopic mechanism for traffic flows' self-organizing phenomenon and set up the physical movement models for vehicles; Synthesize the physical movement models of individual vehicles systematically and construct the traffic flow theory on the macroscopical aspect by applying traffic flow theory; resolve the basic process of traffic flow's self-organizing by using self-organizing theory, study the cooperation and competition in the self-organizing of traffic flows, construct the evalution indexes and approaches for the orderly performance of traffic flow self-organizing and build the forecast models for the evolution of traff
