调查了电动车和自行车之间的超车事件,并探索已有非机动车设施内超车事件数和交通参数之间的关系.应用摄像机观测了3个南京机非隔离的非机动车道路段,并详细分析了包括流量、速度和超越事件特征在内的实际数据.通过数据分析和拟合发现:超车事件与速度差别以及自行车比例相关性较弱;高斯函数可以较好地描述超车事件数和流量(密度)之间的关系;非机动车道的利用水平影响到超车事件密度曲线的拐点位置.研究结论可应用于混合非机动车流中超车事件数的计算和机非隔离非机动车道的宽度设置.
Investigated the overtaking events between electric vehicles and bicycles and explored the relationship between the number of overtaking vehicles and the traffic parameters in the existing non-motor vehicle facilities.The three Nanjing non-isolated non-motorized road sections were observed with the camera and detailed The actual data including traffic, speed and event characteristics were analyzed.According to the data analysis and fitting, it was found that the correlation between passing events and speed and the proportion of bikes was weak.The Gaussian function could describe the number of overtaking events and traffic Density). The utilization of non-motorized lanes affects the position of inflection point of overtaking event density curve.The conclusion can be applied to the calculation of overtaking events in mixed non-motorized vehicles and the width setting of non-isolated non-motorized lanes.
