Problems solved by technology
[0003] One is that it does not have communication functions. Due to the different construction and development times of various traffic control systems in various areas of the city and the differences in road construction planning, the traffic signal control systems in various areas of the city are diversified, and the compatibility between systems is poor. The communication methods are not unified, which is not convenient for the overall management and analysis of traffic signal control data
[0004] The second is that in the regional traffic signal control system, the signal control parameters are adaptively and reasonably configured to achieve coordinated control. The technical problems of implementing real-time monitoring and management of a large number of intersection controllers require a large amount of capital investment and time investment, which cannot be solved in a timely manner. question
[0005] Third, because the regional road network cannot realize the automatic calibration of the basic clock, the reference clock is prone to errors, resulting in the failure of the green wave belt control of continuous multi-intersection road belts
[0006] Fourth, the intelligence of the signal machine is poor, and it lacks the fault self-diagnosis function. When the signal machine at the intersection fails, the signal machine should classify the faults, handle different faults differently, and upload the faults to the control system
[0007] Fifth, it does not have the function of requesting traffic conditions on the road surface and pedestrians crossing the street. If the pedestrian crossing signal machine installed on the road section cannot coordinate with the green wave control of the continuous multi-intersection road belt of the main road, it will have a great impact on the green wave control effect of the main road. It even caused the failure of the control of the green wave belt on the continuous multi-intersection road belt of the main road

The invention discloses a traffic control system for the whole section of a main road based on big data. The main road includes the first to the Nth intersections. The control system includes: a computer control subsystem; The first to Nth positioning and flow density acquisition devices in the Nth intersection are respectively used to collect in real time the first traffic flow information of the first direction that is about to pass through the intersection and send it to the computer control subsystem; the computer control subsystem uses According to the analysis of the first traffic flow information, the first traffic flow density and the first average speed passing through the current intersection are obtained, and the vehicle driving in the first direction from the current intersection is calculated according to the first average speed and the distance from the current intersection to the next intersection. The time to enter the next intersection, according to the time to control the green light turn-on time of the next intersection, so that the vehicles passing the current intersection from the first direction can pass the next intersection smoothly, until the vehicles in the first direction pass through the main road. Nth intersection.
Description
technical field [0001] The invention relates to a traffic control system, in particular to a traffic control system for the whole section of a main road to which each group of traffic lights belongs. Background technique [0002] At present, urban traffic management and traffic control issues such as urban road traffic safety, traffic congestion, and traffic pollution emissions caused by factors such as the structure of urban roads and traffic design, and the supply and demand relationship of the entire city, rely on the current traffic management and signal control. The management mode of road traffic time cannot be collected and analyzed and controlled in real time according to the traffic flow and road traffic conditions on the controlled road. Establish big data application models related to urban traffic, traffic management and traffic control, vehicle road traffic statistics and traffic control based on big data, and realize adaptive traffic signal management, real-tim...
