[0050] A phase-signal comprehensive optimization method for two-way green waves on trunk lines, comprising: phase-signals under multiple groups of traffic structures; phase-signals under multiple groups of traffic structures are composed of multiple phase-signals under single-group traffic structures, and a single group The phase-signal under flow structure consists of the following steps:
[0051] 1) Intersection channelization and traffic flow structure and intersection spacing;
[0052] 2) After determining the key intersection, calculate the required green light duration and theoretical green wave width for each intersection with a given signal period;
[0053] 3) Establish a space-time coordinate system, draw a theoretical green wave map and construct a signal to establish a digital flow-time-signal matrix;
[0054] 4) Using the comprehensive optimization model of the signal cycle, fixed uplink and downlink green zones, optimize the traffic organization scheme, the best ...
