摘要
在有轨电车常用的几种信号优先策略中,绝对信号优先显然对道路交通的影响最大。在工程总体设计阶段,一般通过服务水平的变化分析道路交叉口受到的影响,而服务水平有一定的平均概念。以四相位路口为例,通过变换考察周期的起始位置,计算绝对信号优先下,周期内车流绿信比受到影响。实际工程设计中,参考这种分析方法,论证信号优先策略对道路交通的影响,并对道路交通提出设计建议。
Among all modern tram priority strategies, apparently, the absolute signal priority influences road traffic most. However, change of intersection service level is commonly used to define this influence, which contains a certain mean during the project general design phase. To study this influence, a standard 4-phase intersection is taken as an example in this paper, by changing the start point of the investigated cycle, green signal ratio of certain traffic flow is discussed through calculations. In actual engineering design, this analytical method could be applied to demonstrate the impact on road traffic, and moreover, some advise on the road traffic design are given.
