【摘要】 在城市道路交叉口,电动自行车(简称电动车)对机动车通过交叉口的通行效率产生了很大干扰,本文对电动车产生的干扰进行了研究,通过对昆明市多个交叉口的数据分析,结合交叉口禁左的渠化设计,以绿灯时间内的干扰时间长度(干扰时间)、电动车流量、电动车交叉口越线车辆数为干扰因子,用SPSS分析直行机动车流率和三个因素之间的相关性,确定三个参数的影响系数,重新标定HCM2000中对直行车通行能力的计算公式,计算结果与不受干扰时的数据进行对比,发现在绿灯时间内有25%的直行机动车受干扰,最后通过调查另外五个交叉口,对模型进行验证,对比结果表明,改进后的算法能够更好的反应实际通行能力。更多还原

【Abstract】 In urban road intersections, the bike(electric vehicles for short) produces a great disturbance for the efficient of motor vehicles through the intersection. This paper investigates the disturbance produced by the bike. Through the data analysis of road intersections, combined with the ban left drainage design, the interference time length(interference time) in green time, bike flow, number of electric vehicles crossing the intersection are taken as the interference factor. The correlation between the straight line flow rate and the three factors is analyzed by SPSS to determine the influence coefficient of the three parameters and re-mark the calculation formula of direct motor vehicles traffic capacity of HCM20000. The calculation results are compared with data without interference. It is found that 25% straight motor vehicles are disturbed in green time. Finally, the model is verified by the investigation of other five intersections. Comparison results show that the improved algorithm can better reflect actual capacity.更多还原
