信号交叉口非机动车骑行特性及安全性实验研究

非机动车在信号交叉口骑行涉及安全及通行能力的问题.借助交通行为分析理论,采用摄像机和骑行实验计测系统,针对23名实验者分别进行了非机动车交叉口骑行实验研究,并对骑行者的骑行感受进行了问卷调查.通过调查问卷对被试者的骑行行为分析表明,骑行者感知的主要威胁来自与左侧机动车的冲突.骑行实验数据的分析结果,验证了调查问卷的结论.对非机动车过街的速度、加速度特性分析,论证了非机动车采取二次过街通行方式比直接左转安全性高.

Experimental research on the safety and riding characteristics of non-motorized vehicle at signalized intersection

In order to analyze the safety of the non-motorized vehicles at signalized intersections,the major cause of the conflicts show that the non-motorized vehicles are threatened,23 participants were chosen to take part in the cycling experiment at selected intersections using camera and probe bicycle system.A questionnaire was designed to investigate the feelings of the participants in the process of cycling.The questionnaires show major conflicts that the non-motorized vehicles are threatened by cars coming left,which was verified by the experimental statistics.Through discussion and analysis on the speed and acceleration characteristic of the non-motorized vehicle,it was verified that it is safer for the non-motorized vehicles to choose Twice Crossing Street instead of straight left-turn while crossing the streets.
