Traffic signal lamp intelligent control system

Abstract

The invention provides a traffic signal lamp intelligent control system. The system comprises a first sensing system at a first intersection, a cloud end and a second signal lamp at a second intersection, the first sensing system monitors vehicles coming and going in a first direction at the first intersection and transmits first vehicle data to the cloud end, and the first intersection allows thefirst passing duration in the first direction; the cloud processes the data and then sends an allowable passing parameter in the first direction to a second signal lamp of a second intersection, wherein the allowed passing parameters meet the following formula: T2=T1+tx1+t12, T2 is a starting time point when the second signal lamp is allowed to pass in the first direction, T1 is a starting time point when the first intersection is allowed to pass, tx1 is a first passing duration, and t12 is the driving duration between the first intersection and the second intersection in the first direction.The traffic signal lamp intelligent control system has the technical effects of adjusting traffic lights in real time, improving the green light passing duration of a congested road section, reducingthe green light passing duration of a smooth road section and achieving efficient and continuous passing 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
