Traffic signal lamp intelligent control method

Abstract

The invention provides a traffic signal lamp intelligent control method. The method comprises the following steps of 100, monitoring the vehicles coming and going in a first direction at a first intersection, and transmitting the first vehicle data and the first passing duration allowed by the first intersection in the first direction to a cloud end; 200, enabling the cloud to process the data andthen send an allowable passing parameter in the first direction to a second signal lamp of a second intersection, wherein the allowed passing parameter meets the following conditions that T2 = T1 + tx1 + t12T2 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 the firstpassing duration, and t12 is the driving duration between the first intersection and the second intersection in the first direction. The method has the technical effects of adjusting traffic lights inreal time, improving the green light passing duration of a congested road section, reducing the green light passing duration of a smooth road section and achieving the efficient and continuous passing during peak hours.

Description

Technical field [0001] The invention relates to a traffic signal lamp intelligent control method and its system, in particular to an intelligent video image processing technology, which uses algorithms to calculate the number of vehicles at each intersection and intelligently mobilizes the signal lights to realize rapid vehicle passing. Background technique [0002] At present, in China’s large and medium-sized cities and central and western cities, the number of vehicles on roads during rush hours has been saturated. Especially during rush hours 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 huge waste of time and is easy to cause local air pollution. [0003] There are many reasons for road congestion. One is that the road planning is unreasonable. The main road network is the main road network and the lack of capillary road traffic network. The other major reason is that the road sig...

[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
