Intelligent control method and apparatus for crossroad traffic light

Abstract

The invention relates to an intelligent control method and apparatus for a crossroad traffic light. The method includes the following steps: receiving traffic light information which is uploaded by traffic lights, the traffic light information including traffic light state and traffic light status lasting time; receiving vehicle speed information and crossroad position information which is uploaded by an onboard terminal, based on the traffic light information, the vehicle speed information and the crossroad distance, generating crossroad alert information, and transmitting the crossroad alert information to the onboard terminal and alert the onboard terminal, wherein the crossroad distance refers to the distance between the position of a vehicle and a traffic crossroad. According to the embodiments of the invention, the method herein can automatically determine whether the vehicle can directly pass the crossroad based on the traffic light information, the vehicle speed information and the crossroad distance, and generates corresponding crossroad alert information, reminds a driver to pass the crossroad safely, and increases passage rate of the crossroad when it is guaranteed that the vehicle and pedestrians are safe.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an intelligent control method and device for traffic lights at intersections.

Problems solved by technology

[0002] In the prior art, the transition time of traffic lights is manually set, or traffic lights are more intelligent. The detection device detects the traffic flow in all directions in real time, and adjusts the time of traffic lights according to the traffic flow. Under normal circumstances, if the driver They all abide by the traffic rules and concentrate their attention. This kind of traffic light can adjust the congestion situation in all directions to a certain extent. Passing through the intersection before the end of the light traffic state, resulting in sudden braking at the zebra crossing, or dangerous driving actions such as running a yellow light, which will not only increase the wear and tear on the vehicle to a certain extent, but more importantly, seriously affect the vehicle passing through the intersection. safety at all times, especially for pedestrians passing by

Moreover, the vehicle starts before the red light waiting time is over, or at a relatively remote intersection, the driver usually runs the red light at will because there is no electronic monitoring, these are serious dangerous driving behaviors

In addition, the existing traffic lights cannot effectively remind the driver when the traffic light is switched. Usually, the driver does not notice and runs the red light by mistake, or the driver does not start in time when the light is switched to green, resulting in delays in driving on the road, resulting in traffic accidents on the road. congestion or traffic accident
