The invention discloses an expressway exit ramp and joined intersection main signal and pre-signal combined traffic control method, which comprises the following steps of: firstly, finishing the design of a pre-signal, variable lane and other traffic organization optimization scheme according to the traffic flow characteristics of an expressway exit ramp and an auxiliary road; secondly, completing traffic phase and phase sequence design of the main signal and the pre-signal, determining a control mode of the intersection, and finally establishing a pre-signal traffic signal timing scheme calculation model and a mutual relation model of traffic signal timing of the main signal and the pre-signal; and the traffic capacity maximization of the straight traffic flow of the expressway exit ramp and the connection intersection is realized. According to the invention, the interleaving caused by the simultaneous release of the two traffic flows of the expressway exit ramp and the side road is effectively avoided through the combined control of the main signal and the pre-signal, and the utilization efficiency of space-time resources at the intersection is improved.
本发明公开了一种快速路出口匝道和衔接交叉口主预信号联合通行控制方法,包括如下步骤:首先根据快速路出口匝道和辅路的交通流量特征,完成预信号、可变车道等交通组织优化方案的设计,其次完成主信号和预信号的交通相位和相序设计,确定交叉口的控制方式,最后建立预信号交通信号配时方案计算模型,以及主信号和预信号的交通信号配时的相互关系模型,实现快速路出口匝道和衔接交叉口的直行交通流的通行能力最大化。本发明通过主预信号联合控制有效避免了快速路出口匝道和辅路两股交通流同时放行造成的交织,提升了交叉口时空资源的利用效率。
