基于可接受间隙理论的交通冲突判别方法研究

回顾了国内外关于交通冲突技术的研究现状,介绍已有的交通冲突判别方法,总结近年来国内外学者使用交通冲突判别方法的发展过程.以信号交叉口行人与右转车的交通冲突为研究对象,进行相应的数据采集,并利用SIMI软件提取两者的运动状态数据.选取减速度作为判别标准对两者的交通冲突进行判别,利用可接受间隙理论中的临界间隙法确定减速度判别冲突的临界值,最终对采集的数据进行冲突判别,并得到判别结果.

Research on Methods of Traffic Conflict Discrimination Based on Gap Acceptance Theory

This paper reviewed the existing domestic and foreign research studies about traffic conflicts,existing discrimination methods,and summarized the development process of domestic and foreign scholars using the methods of traffic conflict discrimination in recent years. This paper focuses on traffic conflicts between pedestrians and right turn vehicles at signalized intersections, carries out data acquisition,and extracts the motion data of both by using the software SIMI. The paper selected deceleration as the judgment standard of traffic conflict discrimination,and the critical value can be determined by the speed discrimination acceptance conflict in the theory of the critical gap method. The final data was collected for conflict resolution and used to obtain the findings.
