Embodiment 1

[0066] attached Figure 1-17 It can be seen that it is an anti-locking control system at a signalized intersection, which includes a vehicle detection and sensing device installed at a traffic intersection. The vehicle detection and sensing device includes: a high-definition camera, a ground sensing coil and a microwave detection device. The received vehicle information is transmitted to the signal control center, and its control center controls the traffic of the signal light group at the traffic intersection according to the blocked condition of the signal intersection.

[0067] Signalized intersection obstruction conditions include signalized intersection internal obstruction and signalized intersection external obstruction.

[0068] The signalized intersection is divided into four areas: A, B, C, and D; among them, Area A and Area B are on the same straight line; Area C and Area D are on the same straight line; the traffic direction of BA area and the traffic direction of ...

Embodiment 2

[0087] as attached Figure 1-17 It can be seen that it is an anti-locking control method for a signalized intersection. The control center controls the passage of the signal light group at the traffic intersection according to the obstructed condition of the signalized intersection. The obstructed condition of the signalized intersection includes internal obstruction of the signalized intersection and external obstruction of the signalized intersection. It is characterized by:

[0088] The signalized intersection is divided into four areas: A, B, C, and D; wherein A area and B area are on the same straight line; C area and D area are on the same straight line; BA area vehicle traffic direction and CD area vehicle traffic direction Parallel to each other; the traffic direction of vehicles in A and C area and the traffic direction of DB area are parallel to each other;

[0089] The traffic direction of vehicles in the BA area is from east to west;

[0090] The traffic directio...

Abstract

The invention relates to a signalized intersection anti-locking control system and method, wherein the signalized intersection anti-locking control system comprises a vehicle detecting and sensing device arranged at a traffic intersection; the vehicle detecting and sensing device comprises: a high-definition camera, a ground sensing coil and a microwave detecting device; the vehicle detecting andsensing device transmits the detected vehicle information to a signal control center; the signal control center controls a traffic light group of the traffic intersection according to the blocked state of the signalized intersection. The signalized intersection anti-locking control method can greatly improve the traffic efficiency of a large intersection with obvious time-varying traffic flow, effectively solve insufficient polices, can further alleviate urban traffic congestion, and improve the traffic environment.

Description

technical field [0001] The invention relates to a traffic control system, in particular to an anti-locking control system and method for a signalized intersection. Background technique [0002] With the rapid development of my country's national economy, the urbanization process is accelerating, motor vehicles are increasing rapidly, and the demand for transportation is also increasing sharply. The urban road network is the carrier of urban traffic flow, and the traffic quality of the road network directly determines the operation level of the traffic system. Among them, the road signal intersection can realize the flow distribution of road network communication and become the key link of the whole road network. The signal management and control scheme at signalized intersections is the basis for the allocation of traffic flow rights. The specific control modes include single-point control, cooperative control, and induction control. At the same time, there are also a lot ...
