Intelligent traffic control method for monitoring crossroad traffic accident

Abstract

The invention discloses an intelligent traffic control method for monitoring a crossroad traffic accident. The method comprises the steps that real-time road condition information of a traffic crossroad is received; parking time of any of cars at the crossroad is calculated; position information of the cars with the parking time longer than a time interval of two adjacent green lights is obtained;directions of lanes occupied by the parked cars are judged; according to residual lane data, a traffic flow and car speeds, display time of signal lights is adjusted to obtain adjusted signal light control signals; the control signals are sent to the traffic signal lights. By means of the control method, whether a traffic accident is occurred at the crossroad can be monitored intelligently, and according to a situation of the lanes occupied by the traffic accident, the time of the traffic signal lights is adjusted in time, so that a traffic situation after the accident happens is controlled,the clear crossroad is guaranteed, effects of the traffic accident on traffic are reduced, the cars pass safely, congestion situations of the crossroad are reduced, the time of the signal lights is adjusted in real time, smooth travelling of people is ensured, and the passing efficiency is improved.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to an intelligent traffic control method for monitoring intersection traffic accidents. Background technique [0002] With the increase of urban population, urban traffic problems are becoming more and more prominent. There are many kinds of traffic problems, such as traffic jams, traffic accidents, public transportation, etc. Among them, traffic jams are very important traffic problems. [0003] At present, in many cities, the number of cars has increased sharply. Due to the excessive number of cars, traffic jams are often caused. Moreover, there are more and more types of vehicles at this stage, which can easily cause traffic jams and frequent traffic accidents. And people's normal life has brought a serious impact. Traffic lights at traffic intersections are the guarantee for smooth traffic, but when a traffic accident occurs at a traffic intersection, it will often lead to s...

[0003] At present, in many cities, the number of cars has increased sharply. Due to the excessive number of cars, traffic jams are often caused. Moreover, there are more and more types of vehicles at this stage, which can easily cause traffic jams and frequent traffic accidents. and people's normal lives have been seriously affected

Traffic lights at traffic intersections are the guarantee for smooth traffic, but when a traffic accident occurs at a traffic intersection, it will often lead to slow traffic flow and increased congestion, coupled with the guidance of traffic lights, will make traffic worse, therefore, it is necessary to Improved control of existing signal lights
