本文尝试通过交叉口进口、出口车道数平衡性的分析来评价交叉口。给出了交叉口进口道、出口道车道数平衡性的量化评价指标。以典型的拓宽式多相位信号控制交叉口为例,通过实地勘测,计算每相位下的进口、出口断面的通行能力,根据计算结果评价分析交叉口进口、出口车道数的时间和空间上的平衡性。 This paper tries to evaluate the intersection by the analysis of the balance of the number of entrance and exit lanes at the intersection. The quantitative evaluation indexes of the balance of the number of entrance lane and exit lane of intersection are given. Taking a typical widened and multi-phase signal control intersection as an example, through the field survey, the capacity of each section at the inlet and outlet cross sections is calculated. Based on the calculation results, the time and space balance of the number of intersections and exit lanes are evaluated and analyzed Sex.
