After adopting the coordination control design, the mainstream vehicle flow disturbance caused by pedestrian crossing is effectively reduced, and the mainstream green wave width can meet the requirement of pedestrian crossing.

The necessity and significance of the design of signal coordination control system in urban main roads are represented in the paper, meanwhile, the design flow process of the green wave signal system is displayed.

Based on a method of two-way green wave signal control with each phase for entrance,this paper designed a two-way green wave signal control system for Liansheng Road in Humen,Dongguan.

The paper introduces the idea of bidirectional green-wave signal control in detail and gives a new method to control bidirectional green-wave signal, which proves effective through analysis and the conclusion.
