从错位交叉口自身特点及其对交通流的影响方面讨论了错位交叉口2个T形口距离与信号控制方式的关系,确定了控制方式选择的T形口距离阈值,并从信号控制相位优化和配时优化方面重点介绍了将错位交叉口作为一个大型交叉口进行综合控制的信号优化方法。 This paper discusses the relationship between the distance of two T-shaped mouths and the signal control mode at the dislocated intersection from the characteristics of the dislocated intersection and its impact on the traffic flow, determines the T-shaped mouth distance threshold of the control mode selection, and optimizes the signal- And timing optimization, we focus on the signal optimization method that takes the dislocated intersections as a comprehensive control of large-scale intersections.
