【摘要】：针对在信号交叉口提前右转且无信号控制的条件下,直右混行车道上右转车受直行车阻挡的问题,根据混行车道上交通流特性,确定了交叉口信号周期内提前右转机动车无法进入右转弯道的阻断时间,结合行人流上游所受的信号控制方式,解析了机动车与双向行人的冲突过程,计算了冲突中机动车与行人的通行时间,并在此基础上,建立了提前右转方式下右转车与行人的延误模型.案例计算与分析表明:模型计算值与实际调查值之间的相对误差在20%以内;当机动车流量小于350 pcu/h,机动车对行人通行影响较小,而当机动车流量大于350 pcu/h,行人与机动车的竞争冲突较为明显.
[Abstract]:Under the condition that the signal intersection turns right ahead of time and has no signal control, the traffic flow characteristics on the mixed carriageway are analyzed according to the traffic flow characteristics of the traffic flow on the straight and right mixed carriageway.In this paper, the blocking time that the right turning vehicle cannot enter the right turn road in advance during the intersection signal cycle is determined, and the conflict process between the motor vehicle and the two-way pedestrian is analyzed in combination with the signal control mode in the upper reaches of the pedestrian flow.The passage time of vehicles and pedestrians in conflict is calculated, and on the basis of this, the delay model of right turn and pedestrian in the mode of forward right turn is established.The case calculation and analysis show that the relative error between the calculated value of the model and the actual value of investigation is less than 20%, and when the flow of motor vehicle is less than 350 pcu-h, the influence of motor vehicle on pedestrian passage is small.However, when vehicle flow is greater than 350 pcur / h, the conflict between pedestrian and motor vehicle is obvious.
