【摘要】：将直右共用车道车辆受阻挡情况分为直行红灯期间右转车流未被阻挡、直行红灯期间右转车流被阻挡、滞后放行期间直行车流未被阻挡和滞后放行期间直行车流被阻挡这4种情况,分别计算4种情况发生的概率及对应的通行能力,建立红灯右转和右转滞后放行信号控制条件下的信号交叉口直右共用车道通行能力模型.对典型交叉口的VISSIM开展仿真验证.结果表明,采用该模型能够精确地估计红灯右转和右转滞后放行条件下的直右共用车道通行能力,直右共用车道通行能力随着滞后放行时间的增加而减小.直右共用车道的通行能力与转向比例成负相关,与有效绿灯时间成正相关.
[Abstract]:Divide the obstructed traffic in the straight right common lane into two categories: the right-turn traffic flow is not blocked during the straight red light, and the right-turn traffic flow is blocked during the straight red light.In the four cases that the direct traffic flow is not blocked during the delay release period and the direct traffic flow is blocked during the delay release period, the probability and the corresponding capacity of the four cases are calculated respectively.The traffic capacity model of the signalized intersection under the condition of red light right turn and right turn lag release signal control is established.The VISSIM of typical intersection is simulated and verified.The results show that the model can accurately estimate the traffic capacity of the straight right common lane under the condition of red light right turn and right turn lag release, and the capacity of the straight right common lane decreases with the increase of the lag release time.There is a negative correlation between the traffic capacity and the steering ratio and a positive correlation between the traffic capacity and the effective green time.
