作为弱势交通群体，行人在交通事故中最易受到伤害。为提升行人安全，本项目拟从分析行人过街行为机理出发，遵循行为干预的原理，提出行人过街安全提升方法。围绕行人个体过街与群体过街的差异性，探究外因和内因作用下，行人过街的行为模式与心理规律，构建行人个体过街、结伴过街和从众过街行为的决策模型；考虑外部客观因素，基于设施因素对行人过街行为的影响效应，提出行人信号、二次过街设施、安全过街智能辅助设施等的设置方法；考虑行为本因，基于行为的心理学建模结论，对违法过街行为进行心理干预和行为干预，提出面向不同群体、针对不同行为的行人交通安全宣教方法。预期成果可为相关部门开展行人安全意识培养、过街设施规划设计、行人行为管理提供理论指导和决策依据，从而有效减少行人交通事故，营造以安全为基调，人、车、路协调发展的交通环境。

Pedestrians are more likely to be injured in traffic accidents, as they are the most vulnerable road users. To improve pedestrian safety, following the idea of behavior intervention, this project is to provide some safety improving methods, starting with the study of pedestrian crossing behavior. By considering the differences between individual and group behaviors, we investigate the effects of external factors and internal factors to build decision-making models for individual, company and conformity behaviors. According to the results of decision-making models under the facility condition, some designing methods are studied for pedestrian facilities such as signal, twice crossing facility and intelligent supporting facility. Based on the psychology modeling conclusions about illegal crossing behaviors and by using the idea of psychological and behavior intervention, some pedestrian traffic safety education methods are proposed for different groups and behaviors. Our expected results in this project are to provide the theoretical evidence for the safety awareness training, pedestrian facility design, behavior management, reducing pedestrian accidents, and create a safety and coordinated traffic environment.
