A traffic signal control technology is adopted, and four-way green waves and surface control with a four-way green wave effect are implemented at a planar intersection of an urban road network. The design method is mainly a three-dimensional model method, a planar time-distance diagram method is a simplification of the method. The method further comprises other mathematical models, computer programs, animation trial and error backstepping and other methods which follow the thought of the three-dimensional model method and do not need to display a three-dimensional model and a planar time-distance diagram. All the methods conform to the principle that: a longitudinal road time vertical face and a transverse road time vertical face of each intersection intersect on a time axis and uplink anddownlink signal stages of the bidirectional green waves on the two vertical faces are made to coincide or intersect as much as possible on the time axis; if the uplink and downlink signal stages of the bidirectional green waves on the two vertical faces are away from each other, other phases can be inserted in the leaving time, and the release stage of the bidirectional green waves on the longitudinal vertical face and the release stage of the bidirectional green waves on the transverse vertical face are thoroughly separated. Therefore, a comprehensive or discrete four-way green wave model and method with the functions of design, verification, simulation display, data reporting, online operation and the like are established.
采用交通信号控制技术,在城市路网的平面十字路口实行四向绿波及具有四向绿波效果的面控。设计方法主要为立体模型法,平面时距图法是该方法的简化,还包括既遵循立体模型法的思路又不必显示立体模型和平面时距图的其他数学模型、计算机程序、动画试错反推等方法。所有方法都遵守的原则是:在每路口的纵向道路时间立面和横向道路时间立面相交的时间轴上,分别让两个立面上各自双向绿波的上、下行信号阶段尽量重合或相交,若相离,则要让离开的时间能够插入其他相位,让纵向立面上的双向绿波的放行阶段与横向立面上的双向绿波的放行阶段彻底分开。据此,建立了综合或分立的具有设计、验证、仿真显示、报告数据、在线运行等功能的四向绿波模型、方法。
