为避免信号交叉口驶入出口道的车辆受到路内停车带的影响而得不到正常疏散或形成拥堵,以设置有路内停车带的信号控制交叉口出口道为研究对象,从路内停车对交叉口出口道动态交通影响分析入手,考虑路内停车和信号控制的共同作用,运用交通流波动理论,分别构建了停车带长度有限的和全路段均有停车带的2种情况下路内停车最佳距离的计算方法。以南京市成贤街路内停车带为例,进行实例应用,并重点分析了交叉口出口道处路内停车最佳距离随着交叉口到达流量、进入停车带后路段流量、信号控制参数周期时长、绿灯时长以及路内停车带长度变化的规律。结果表明,最佳距离随着交叉口到达流量和停车带长度的变化存在显著的变化拐点,而交叉口周期时长和绿灯时间比例均对路内停车设置位置存在显著影响。
In order to avoid that the vehicles entering the exit road at the signalized intersection can not get the normal evacuation or congestion due to the influence of the on-street parking belt, and the signal of the in-lane parking zone is set to control the exit of the intersection as the research object, Starting with the analysis of the impact of dynamic traffic at the exit of the intersection, considering the common action of on-street parking and signal control, the traffic flow fluctuation theory is used to construct two kinds of cases where the parking zone has a limited length and parking zones are all on the road Calculation of the optimal distance for parking. Taking the parking belt in the road of Chengxian Street in Nanjing as an example, the practical application is given. The optimal distance between the exit road at the intersection and the traffic flow at the intersection is analyzed. The traffic flow after entering the parking zone, the period of signal control parameters , The length of the green light and the length of the parking zone with the law. The results show that there is a significant inflection point of the optimal distance with the change of traffic arrival and parking zone length, and the intersection cycle time and the green time proportion have a significant impact on the on-street parking location.
