Abstract
The invention discloses a traffic control system based on traffic flow, comprising traffic lights, a vehicle counter P and an intelligent traffic light control center, wherein the traffic lights and the vehicle counter P are connected with the intelligent traffic light control center; the intelligent traffic light control center realizes intelligent control, and can effectively control signals of the red light and the green light of the traffic lights according to the real-time traffic flow, wherein the time length of each red and green light change satisfies current traffic flow information; when the intelligent traffic light control center calculates the time length of the green light, a margin is added, thus ensuring that vehicles entering a road section within a straight traffic period can pass through an intersection, effectively improving the current situation of urban traffic jam and reducing traffic accidents.
Description
Technical field
The application relates to urban traffic control field, is specifically related to a kind of traffic control method based on vehicle flowrate.
Background technology
Traffic control, is also traffic signalization, or urban traffic control, be exactly rely on traffic police or adopt traffic signalization facility, commands that vehicle and pedestrian's is current with traffic variation characteristic.
Traffic control uses modern communications service, telltale, sensor, watch-dog and computing machine to organize exactly operating vehicle, regulate and control, and can run safe and smoothly.Traffic control is divided into static management and dynamic management, and traffic control is exactly dynamic management wherein.
Traffic control reduces traffic total amount by being limited traffic flow by the traffic control device of computer management, regulating, induce, shunt to reach, and relieves traffic congestion, ensures traffic safety and unimpeded object.
In recent years, Britain, Australia, Europe and the U.S. all establish traffic control system in some city.In such systems, major part is all provided with magnetic rings circuit detector near each crossing, and by the control device at each crossing or staff by traffic control parameter by communication network input microprocessors such as telephone wire, cable, closed-circuit television lines, carry out centralized control with small-size computer.
The urban traffic control of current domestic more existing independent developments and management system, but still have larger gap at overall performance than external homogeneous system, some application are only obtained in some small and medium-sized cities.The domestic city traffic system major part that especially big city is introduced is SCOOT and the SCATS system of import.Because China's traffic flow is mixed traffic flow, and external traffic flow differs widely, and external traffic control system result of use is at home unsatisfactory.Compared with abroad, the current traffic of China is also relatively backward, is mainly manifested in:
(1) urban road unreasonable structure, most cities road space structure belongs to plane traffic behavior, forms the feature of " the mixed row of people's car, speed car is mixed to be sailed ".Primary and secondary arterial highway and branch line out of proportion, joining relation is disorderly, makes arterial road be difficult to play its function.With regard to path area, domestic urban road area ratio is lower than same size big city in the world.
(2) traffic trip unbalance of structure.Domestic urban transportation is formed primarily of various motor vehicle, bicycle and pedestrian, forms special ternary mixed traffic structure.
(3) traffic management technology level is low, frequent accidents.The problem of current Urban Transport presents two quasi-representative phenomenons: manage ineffective, disorder; There is no science, reasonable, effective City Traffic Monitor System.The consequence brought thus is on the rise.Show as the road network traffic capacity and be starkly lower than designing requirement and undulatory property is large, the travel time is difficult to prediction, traffic hazard occurred frequently, traffic environment worsen, traveler easily fatigue etc.
In urban transportation, often because the traffic lights duration of the craspedodrome of traffic lights, left-hand rotation and right-hand rotation distributes uneven, cause vehicle congestion, very easily traffic hazard occurs.
Summary of the invention
The present invention, in order to solving urban traffic blocking situation, carries out Based Intelligent Control for the busy busy in urban transportation, thus effectively improves the present situation of urban traffic congestion, reduces the generation of traffic hazard.
