本文在理论与实践上,就几种常用车辆到达分布规律进行了观察与研究。在此研究的基础上,用概率的方法,推导出考虑车序等因素的车辆换算系数公式,从而可用车辆换算法计算信号交叉口的通行能力。至于行人与非机动车对机动车的干扰,用机动车有效绿灯时间的减少来体现。在信号配时方面,提出了既考虑延误,又考虑油耗的最佳周期公式。
In this paper, in theory and practice, several commonly used vehicle arrival distribution were observed and studied. On the basis of this study, by using the method of probability, the formula of vehicle conversion factor considering vehicle sequencing and other factors is deduced, so that the traffic conversion method can be used to calculate the traffic capacity of signalized intersections. As for pedestrians and non-motor vehicles on the interference of motor vehicles, with the vehicle to reduce the effective green time to reflect. In terms of signal timing, the best periodic formula that considers both delay and fuel consumption is proposed.
