Traffic signal coordinated control optimization: A case study

In the urban traffic network, intersection is the “bottleneck point” of road network capacity. And the arterial is the main body in road network and the key factor which guarantees the normal operation of the city´s social and economic activities. The rapid increase in vehicles leads to seriously traffic jam and causes the increment of vehicles´ delay. Most cities of our country are traditional single control system, which can´t meet the need for the city traffic any longer. In this paper, Synchro6.0 is used as a platform to minimize the intersection delay, optimize single signal cycle and split for Zhonghua Street in Handan City. Meanwhile, linear control system is used to optimize the phase for the arterial road in this system. Comparing before and after the control, both the capacities and service levels of this road and the adjacent roads are improved significantly.
