无信号控制路口行人过街行为特征及博弈模型分析

Pedestrians' Behavioral Characteristics and a Game Theoretical Analysis while Crossing an Unsigned Intersection

过城市实地行人问卷调查及过街行为分析,描述了行人过街重要行为特征,在此基础上,引入了交通工程相关结果,针对无信号控制路口行人过街问题,构建了行人先行和车辆先行的扩展式行人过街冲突博弈模型。纳什均衡分析结果揭示了行人过街冲突的机理,并给出了各种冲突情况下相应参数临界分析。预期结果对行人过街设施的管理与建设也具有意义。

Throagh the questionnaire analysis of spot towards pedestrians and their crossing behavior, some key factors are presented. Furthermore, pedestrian crossing related research of transportation engineering is intro- duced and two kinds of game theoretic model, pedestrian first move model and automobile first move model are constructed in the extensive form. Equilibrium depicts the mechanism of pedestrians＇ crossing. Besides, the range of coefficients respect to different kinds of conflicts is also processed. The outcome of this paper is also meaningful for administration and construction of pedestrian related facilities.
