摘要
为研究信号交叉口行人与非机动车的干扰机理,通过对拍摄的视频进行标定,获取行人与非机动车在穿越信号交叉口过程中每间隔0.1s的瞬时位置、速度、加速度数据,通过分析行人与非机动车运行轨迹的重合程度,研究行人与非机动车各类型出行方式之间的干扰程度;通过分析干扰和非干扰状态下行人与非机动车的水平偏移量、速度、加速度以及加速度方差的不同,研究干扰对行人与非机动车运动产生的影响。研究结果表明,行人受干扰时,水平偏移量是主要改变量;电动自行车和电动三轮车受干扰时,速度是主要改变量;自行车受干扰时,水平偏移量和速度都有变化;干扰对行人和非机动车的加速度有一定影响,但是影响不大。
In order to study the interference mechanism between pedestrians and non-motor vehicles at signalized intersections,their instantaneous positions,velocities and acceleration data in each0.1s during the process of crossing the signalized intersection were obtained by calibrating the shooting video.Through analyzing the coincidence degree of pedestrians′and non-motor vehicles′running tracks,the interference degrees between pedestrians and non-motor vehicles were studied.Based on the analysis of the differences of horizontal offsets,velocities,accelerations and acceleration variances between pedestrians and non-motor vehicles in the state of interference and non-interference,the effects of disturbance on the movement of pedestrians and non-motor vehicles were studied.The results show that when pedestrians are disturbed,their horizontal offsets are the main changes.When electric bikes and electric tricycles are disrupted,their velocities are the main changes.When bicycles are disturbed,the horizontal deviations and velocities vary.Interference has some effect on the accelerations of pedestrians and non-motor vehicles but not so much.
