交叉口信号灯设计、车道功能划分等管理措施对其运行效果有重要影响。目前尚无指标可用于评价交叉口管理措施的合理性。本文首次提出交叉口利用水平的概念,用以表征交叉口的充分利用程度,从一个方面反映了管理措施的合理性。文中给出交叉口利用水平指数的计算公式和计算流程,并根据上海市部分交叉口的分析结果建立初步评价标准。
Intersection of signal design, lane division and other management measures have a significant impact on the operation of its effect. There are currently no indicators that can be used to assess the rationality of management measures at intersections. This paper presents for the first time the concept of the level of utilization of intersections to characterize the degree of full utilization of intersections and reflects the rationality of management measures on the one hand. The calculation formula and calculation flow of the level index at intersections are given in this paper, and the preliminary evaluation criteria are established based on the analysis results of some intersections in Shanghai.
