And main roads that are the backbone line of urban work connects each urban functional partition and the key control nodes, whether t he highway traffic is unobstructed or not affects the whole city ’s traffic effectiveness. If the signal c ontrol of the highway interaction is unrelated, that is, taking one signal control with one signal point respectively, the vehicles would go and stop ing across red lights on the road, causing p roblems such as traffic jam, environmental pollution and the waste the strategy, the c ontrol of the main signal coordination is put forward, it can connect a group of adjacent signal intersections on the trunk line, thus coordinating control and decreasing the parking frequency for v ehicles in each intersection, especially making the vehicles on the trunk line run smoothly, then the c oordination control system of intersection traffic signal on the main road appears. This paper takes GuYang main road in zhenJiang as the research object, first, the basic p rinciple and design method of signal coordination control i
