Specific vehicle crossing signal priority control system and method thereof

Abstract

The invention provides a specific vehicle crossing signal priority control system and a method thereof. A priority guidance function can be automatically and rapidly enforced to a specific vehicle which is installed with a vehicle positioning unit. According to a driving direction of the specific vehicle, a priority passing phase of the specific vehicle is determined. According to driving speed of the specific vehicle and a distance of the specific vehicle from a crossing center, an opportunity of providing a priority passing signal for the specific vehicle is determined. When the opportunity of providing the priority passing signal for the specific vehicle arrives, the system automatically provides the priority passing signal for the specific vehicle. When the specific vehicle passes a crossing, the priority passing signal is automatically removed so as to reduce influence on normal traffic.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a signal priority control system and method for a specific vehicle intersection. Background technique [0002] At present, urban road traffic pressure is very high. Although road conditions and traffic signal facilities have been greatly improved, the difficulty of driving is still the main problem of urban road traffic. Traffic jams and traffic jams are still prominent problems plaguing urban traffic. Especially in big cities with poor road traffic capacity, the problem of traffic jam is more serious. Therefore, when there are specific vehicles that need priority passage (such as ambulances performing emergency rescue, fire engines performing firefighting missions, special service vehicles performing special official duties, etc.), time delays are often caused by being blocked by congested intersections. Since the state of the signal lights at the intersec...

Problems solved by technology

[0005] What the present invention aims to solve is that the traffic signal control device in the prior art receives the priority traffic request signal sent by the vehicle and provides the vehicle with the priority traffic signal. Slow and too early to provide priority traffic signals for technical issues that affect normal traffic, and then provide a specific vehicle intersection signal priority based on GPS positioning that can provide priority traffic signals based on the actual driving speed and position of the vehicle and predict the time it will arrive at the intersection Control system and method
