Intelligent control method for traffic light at highway intersection

Abstract

The invention provides an intelligent control method for a traffic light at a highway intersection, and belongs to the technical field of traffic signal light control methods. The intelligent control method comprises the steps of setting a lane and traffic flow detection meter for detecting lane sections of the lane and the traffic flow, setting the traffic light, and setting up an information processor for analyzing and processing the traffic flow and controlling the traffic light. The intelligent control method has the advantages that coexistence of lane blocking and lane idleness is eliminated, and whatever any time periods, any time frames and any reasons, all lane resources of the highway intersection are can be utilized to the maximum extent, intersection traffic efficiency is improved; due to improvement of the traffic efficiency, reactive power consumption of vehicle fuel and energy is reduced to the maximum extent, expenses and time are saved, and waste gas emission is reduced; waiting time for passing of a vehicle driver is relatively reduced in lane sections or time periods with a few traffic flow, impatient emotion of the driver can be effectively relieved, and second rushing, lane rushing and traffic accidents due to the second rushing and lane rushing are reduced.

Description

technical field [0001] The invention belongs to the technical field of control methods for traffic signal lamps, and in particular relates to an intelligent control method for traffic signal lamps at road crossings. Background technique [0002] Traffic lights or the command of the traffic police are required for the traffic of vehicles in the lanes of each direction at the road crossing. The existing traffic signal light command technology and method use green, yellow and red three-color indication, conversion and delay to command the passage (green), deceleration and stop prompt (yellow) and prohibition (red) of vehicles in the corresponding lane; If there are parallel lanes in the lane, the traffic signal lights are also provided with guiding arrows indicating the driving direction of the vehicle and indications, conversions, delays and prompting seconds for each lane. [0003] The traffic signal lights are set in front of the driver in the corresponding lane at the inte...

AI Technical Summary

Problems solved by technology

There are following shortcoming in this highway traffic signal command technology and method: 1. the actual traffic flow of each lane of highway crossing road is because at different periods, different periods and other various reasons are ever-changing, it is impossible to communicate with the signal light command time of fixed setting Consistent with each other, it often leads to the coexistence of waiting, congestion and idling in each lane at the intersection, which reduces the efficiency of crossing traffic and wastes lane resources

2. The waiting and congestion of lanes will inevitably consume fuel and energy without power, causing waste, and increasing carbon emissions and polluting the atmosphere

3. It is easy to make the driver feel anxious, increase the behavior of rushing to the second and rushing to the road, thus causing more traffic accidents

Although this patent application proposes dynamic analysis and directing the passage of vehicles in each lane, it does not explain what means and approaches are used to achieve it. Moreover, changing the driving direction of the lane will also make the drivers of vehicles who have entered the lane at a loss, and lane confusion is prone to occur. and driving violations
