【正文】 At the same time in the city road work all kinds of traffic flow (motor vehicle, the motor vehicle, pedestrians) in the cross each other through the shunt turned, visible intersection of city road work is the most important position. But the intersection is traffic and traffic accidents of the multiple sites. City road transport vehicle efficiency, road safety degree, intersection traffic capacity, the service level of the road to the environment and the influence of the energy basically depends on the urban road crossing capacity. In the urban road intersections control and optimization of the most mon is the signal of control, signal control of a single point signal intersection control and optimization of city road is based. City road intersection of scientific reasonable signal control and optimization, is to improve the city traffic safety and the intersection traffic capacity, reduce the effective measures to stop intersection delay, can ease congestion 。s concern. How to carry out the scientific management of city intersection of this section is to talk 6 about the problem. Implementation of the control mode depends on the geometrical characteristics of the intersection and traffic conditions the purpose is to ensure the intersection of traffic safety and and give full play to the crossing capacity. This section mainly intersections is given priority to, to discuss all to no control intersection and massive priority intersection control, and briefly introduced the basic points of modern ring intersection. The single intersection control strategy of the upstream and downstream will road intersection traffic produce very big effect, intersection upstream and downstream the closer the greater the traffic flow, the greater the effect will be. The traffic signal point control is to separate out the intersection of the separate analysis, and carry on the single signal optimization and road control strategy, and don39。 Sometimes the division of the results is to bee a point, line, face the prehensive control of hierarchical control system. Now on the city road for regional coordination control is dividing the multilevel more signal control branch area, the son o
