| 摘 要： | 通过分析直行自行车与右转和左转机动车之间的冲突规律,采用冲突区占有率方法,研究了直行自行车对机动车饱和流率的修正系数,建立了直行自行车与右转机动车对冲突区占有率的关系模型,结果表明直行自行车对冲突区的占有率随着流量的增加而增加,进而标定了其对机动车饱和流率的影响系数。针对左转机动车,通过分析车流运行特性和通行规则,建立了直行机动车对冲突区的占有率模型,并以此为基础标定了直行自行车对左转机动车饱和流率的修正系数。本文的研究成果为机非混行条件下交叉口的通行能力计算和信号配时方案设计提供了依据。 |

| Abstract: | By analyzing conflict regularity of right-turn vehicle-bicycle and left-turn vehicle-bicycle,the corrective coefficient of straight-going bicycle to vehicle saturation rate is studied with method of occupancy rate on conflict district.The relationship model of occupancy rate of straight-going bicycle and right-turn vehicle is established.The result shows that occupancy rate of straight-going bicycle increases with the increases of the flow rate.Then the corrective coefficient of straight-going to vehicle saturation is demarcated.The model of straight-going vehicle and left-turn vehicle is also set up through analyzing operation characteristic and running regulation.And then the corrective coefficient of straight-going bicycle to left-turn vehicle is demarcated.The paper provided a theory basis on capacity computation and signal timing for mixed condition including bicycle and vehicle at intersection. |
| Keywords: | traffic engineering saturation rate occupancy rate motor vehicle straight-going bicycle mixed traffic vehicle-bicycle conflict capacity |
