摘要
通过行车实验,调查了3条典型双车道共108个路段上的行车速度,得到了单个路侧干扰因素影响时的实验车连续变化速度,分析认为在经过有路侧干扰存在的路段,实验车的初速度与横向间距是影响车速变化的主要因素.采用统计回归方法建立了单个路侧干扰因素对实验车速度的影响模型.在此基础上,通过理论分析,对路侧干扰数量与运行速度之间的关系进行了研究,提出了路侧干扰系数模型,并求出了不同横断面尺寸和路侧干扰数量的路侧干扰系数.
Firstly,experiments are conducted on 108 sections of 3 typical two-lane highways and the continuous speed of cars for experiments are obtained.Then the speed features are studied in these processes,and the conclusion is drawn that the original speed and the transverse space between car and the roadside intruders are the primary factors influencing a car when it passes through.The models of the impact on the speed are also built using regression analysis.On this condition,roadside interference coefficients were put forward based on the theoretic analysis of the relations between the number of roadside interferences and operating speed.Finally,this paper offers a calculated table of the roadside interference coefficient of every kind of transect and varied number of roadside interferences.
