摘要
以间隙接受理论为基础,运用蒙特卡罗法,对无控制交叉口通行能力进行研究.以当量人群描述非机动车和行人对机动车通行的共同影响,模拟机动车流通过交叉口,冲突方向机动车流和当量人群流的到达时距数据由随机数表法获得.经过仿真,分别确定了无控制交叉口车道右转、直行及左转的通行能力,在此基础上得到该方向进口道通行能力.仿真过程接近车辆通过交叉口的现实情况,克服了以往公式法计算通行能力的抽象性.
Based on gap reception theory,the Monte Carlo method was used to study the traffic capacity of uncontrolled intersection.The equivalent people group was adopted to describe the influence of non-motorized vehicles and pedestrians on vehicles to simulate the vehicles through the intersection.The arrival headway data of vehicle and equivalent people was obtained by means of random number table.After the simulation,the traffic capacity of uncontrolled intersection of right-turn,straight-going and left-turn was calculated separately.The simulation process is close to the situation of vehicles through the intersection in reality,which overcomes the abstractness of the traditional formula method to calculate the traffic capacity.
