Management, induction and control system of urban traffic

Abstract

The invention relates to a management, induction and control system of urban traffic, which solves a problem of technology integration of a traffic signal control subsystem, a traffic induction display subsystem, a traffic monitoring subsystem and a mobile early-warning subsystem of the intelligent early-warning subsystem. The invention is characterized in that: a traffic database is in bidirectional connection with the traffic signal control subsystem, the traffic induction display subsystem, the traffic monitoring subsystem and the mobile early-warning subsystem and a traffic information issuing subsystem; and multi-source data fusion of detectors, which includes a microwave probe, a video probe, an ultrasonic probe, a geomagnetic coil, a wireless geomagnetic head, and a geomagnetic detecting head and the like. The beneficial effects are as follows: various data formats are converted into a format of a same standard; the share of traffic basic data and historical data is allowed; the levels of intellectualization, informatization and visualization of urban traffic management are improved; stop frequency is reduced, travel time is shortened, and discharge of automobile exhaust isreduced; and reliable guarantee is provided for energy conservation and travel safety.

Description

technical field [0001] The invention belongs to an electronic information system, in particular to an intelligent traffic management control system, especially to an urban traffic management induction control system. Background technique [0002] In the prior art, the intelligent traffic management control system includes a traffic signal control subsystem, a traffic guidance display subsystem, a traffic monitoring subsystem and a mobile early warning subsystem. Among them, the traffic signal control system utilizes computers, communications and modern control technologies. By optimizing the timing of traffic lights on the road network, the traffic flow in the traffic network in the controlled area can be operated in an orderly and safe manner, so as to reduce traffic jams and shorten travel time. Traffic control mainly affects traffic flow in terms of time; the traffic guidance display sub The system can provide travelers with road network traffic status information, so tha...

AI Technical Summary

Problems solved by technology

In the traffic system of the prior art, the above four systems operate independently, and the basic traffic information and historical data used cannot be shared, so that the final effect is not good

In particular, in the existing signal control systems, most vehicle detectors use geomagnetic coils. However, in practical applications, geomagnetic coils cover the entire lane. Damage to the geomagnetic coil. Once the geomagnetic coil is damaged, the entire adaptive control system will lose the measured data, and all real-time optimization controls will fail, and the entire system will be reduced to the lowest level of timing point control.

In addition, in the existing control system, the control parameters of the signal machine to the signal light are obtained by the host computer (traffic control server) through various optimization algorithms, and then issued to the signal machine. The signal machine is only a controller and cannot be carried out on site. On-line setting, in the line control of main roads, the patchwork method is used to realize the two-way green wave, not only the effect is poor, but also the green light time of the branch road is greatly lost, while in the surface control (regional traffic network), the physical combination of line control and point control is adopted, Not actually zone real-time adaptive zone control
