A kind of intelligent control method of traffic signal light

Abstract

The present invention provides an intelligent control method for traffic signal lights, comprising: step 100: monitoring passing vehicles in a first direction at a first intersection, transmitting the first vehicle data to the cloud, and the first vehicle data allowed by the first intersection in the first direction. Passing time; Step 200: After the cloud processes the data, it sends the allowed passing parameters in the first direction to the second signal light at the second intersection; the allowed passing parameters satisfy: T2=T1+tx1+t12T2 is the second The start time of the traffic light in the first direction, T1 is the start time of the first crossing, tx1 is the first passing time, and t12 is the distance between the first crossing and the second crossing in the first direction. Upward travel time. It has the technical effect of real-time adjustment of traffic lights, increasing the length of green light passage on congested road sections, reducing the length of green light passage on smooth road sections, and achieving efficient and continuous traffic during peak hours.

Description

technical field [0001] The invention relates to an intelligent control method and system for traffic signal lamps, in particular to an intelligent video image processing technology, which uses an algorithm to calculate the number of vehicles at each intersection, and intelligently mobilizes signal lamps to realize rapid passage of vehicles. Background technique [0002] At present, in China's large and medium-sized cities, as well as in the central and western cities, the number of vehicles carried on the roads during peak hours is expected to be saturated. Especially during the peak hours of commuting every day, the problem of vehicle congestion is serious. In extreme cases, the travel time of a single intersection exceeds 30 minutes. It is a great waste of time and is likely to cause local air pollution. [0003] There are many reasons for road congestion. One is that the road planning is unreasonable, mainly based on the main road network, and lacks the capillary road tra...

[0002] At present, in China's large and medium-sized cities, as well as in the central and western cities, the number of vehicles carried on the roads during peak hours is expected to be saturated. Especially during the peak hours of commuting every day, the problem of vehicle congestion is serious. In extreme cases, the travel time of a single intersection exceeds 30 minutes. A great waste of time and easy to cause local air pollution

[0003] There are many reasons for road congestion. One is that the road planning is unreasonable, mainly based on the main road network, and lacks the capillary traffic network; another major reason is that the road signal lights are not set in a standardized manner, and the ability to guide traffic according to the signal lights is low. The traffic signal light system The workflow and rhythm remain unchanged 24 hours a day, and it is impossible to make timely adjustments to real-time traffic conditions. Congested roads are blocked, and long-term green light signals allocated to smooth roads cause waste. And a signal light for hundreds of meters, the vehicle has just waited for one Red light, when reaching the next intersection, it will be red light for tens of seconds again, so repeated, resulting in large-scale tidal traffic, unable to form high-probability, high-efficiency continuous traffic
