摘要:为充分利用交叉口有限的进出口车道资源,提升交叉口时空资源利用率及通行能力,采用基于预信号的交叉口几何设
计方法,构建了以最大化通行能力为目标的交叉口车道划分模型及配时方案求解模型。在此基础上考虑车辆随机到达性,
提出了基于实时交通需求的预信号动态控制方法。最后,基于实例,通过对比不同信号控制方案下的运行情况,利用VIS-
SIM仿真平台进行验证,仿真结果表明:相较于传统的交叉口控制方法,所提出的车道划分模型及信号动态控制算法可有效
提升交叉口通行能力并减小延误。

ABSTRACT;To fully utilize the limited amounts of entrance and exit lanes, improve the utilization of space-time re­
sources ,and increase the capacity at intersections, a lane allocation model and a signal timing model were proposed
with the usage of pre-signal based geometric design method for intersections, which manages to maximum the inter­
section capacity. Further, con s
