【摘要】：电动自行车由于自身方便、快捷的特点越来越受到人们的喜爱。同时由于道路中电动自行车数量的迅速增长,严重影响了道路和交叉口的交通安全和通行效率。尤其是在平面交叉口中,混行条件下电动自行车与机动车的交通冲突现象十分严重,交通事故时有发生。因此,研究城市道路交叉口电动自行车与机动车交通冲突具有重要的现实意义。论文首先通过调查了解,研究了电动自行车的车辆特征和使用特征。根据实际的调查数据,对桂林市的五个交叉口电动自行车车辆到达分布规律进行了详细的分析,总结出城市平面交叉口各进口道电动自行车的到达分布服从负二项分布,得出其在交叉口进口道排队的平均密度和最大密度。其次研究了其释放规律,得到了释放时的饱和流率和行驶速度。根据实际调查,本文详细研究了电动自行车在平面交叉口的微观行驶行为,分析了平面交叉口右转机动车与直行电动自行车之间相互穿越的微观行为,根据它们之间相互穿越的特点,建立了其穿越选择概率模型一Logistic回归模型,然后根据桂林市交叉口实际调查的数据分析了影响交叉口内直行电动自行车与右转机动车之间相互穿越活动决策因素的显著性,标定了Logistic回归模型的参数。最后对建立的Logistic模型进行验证。重点分析了电动自行车与机动车的交通冲突,研究了电动自行车对机动车通行效率的影响,通过实际调查数据统计分析,提出了右转和直行机动车饱和流率的修正系数。最后,分析信号控制交叉口电动自行车释放规律、到达规律和冲突条件,建立了其与右转机动车冲突概率计算模型,并通过实际调查数据计算出具体交叉口这两股车流的冲突概率。
[Abstract]:Electric bicycle is more and more popular because of its convenience and speed. At the same time, due to the rapid growth of the number of electric bicycles in roads, the traffic safety and efficiency of roads and intersections are seriously affected. Especially in the intersection, the traffic conflict between electric bicycle and motor vehicle is very serious under the condition of mixed operation, and traffic accidents occur from time to time. Therefore, it is of great practical significance to study the conflicts between electric bicycles and motor vehicles at urban road intersections. First of all, through investigation and understanding, the paper studies the vehicle characteristics and usage characteristics of electric bicycle. According to the actual investigation data, the arrival distribution law of electric bicycle vehicles at five intersections in Guilin is analyzed in detail, and the arrival distribution of electric bicycles in the entrance roads of urban intersections is summed up according to the negative binomial distribution. The average density and maximum density of the queue at the intersection entrance are obtained. Secondly, the release law is studied, and the saturated flow rate and driving speed are obtained. According to the actual investigation, the micro driving behavior of electric bicycle at the intersection is studied in detail, and the micro behavior of the right turning vehicle and the straight electric bicycle passing through each other at the intersection is analyzed. According to the characteristics of the traversing between them, the Logistic regression model, which is the probability model of traversing selection, is established. Then, according to the actual investigation data of intersection in Guilin city, the significance of influencing factors of intercrossing decision-making between electric bicycle and right-turn motor vehicle in intersection is analyzed, and the parameters of Logistic regression model are calibrated. Finally, the established Logistic model is verified. The traffic conflict between electric bicycle and motor vehicle is analyzed emphatically, and the influence of electric bicycle on the traffic efficiency of motor vehicle is studied. Through the statistical analysis of actual investigation data, the correction coefficient of saturated flow rate of right-turn and direct motor vehicle is put forward. Finally, the release rule, arrival rule and conflict condition of electric bicycle at signal-controlled intersection are analyzed, and the probability model of collision between the vehicle and the right-turn vehicle is established. The conflict probability of the two traffic streams at the intersection is calculated by the actual investigation data.
