Method for controlling traffic signal lamps of crossroad

Abstract

The invention discloses a method for controlling traffic signal lamps of a crossroad. The method comprises the steps of: aiming at the crossroad to arrange a plurality of groups of monitoring devices with a wire and / or wireless transmission function for monitoring vehicles on roads in various directions in certain range area of the crossroad; then transmitting vehicle data obtained by the monitoring devices to a control unit such as a computer device for processing, for example, calculating difference values and proportion relation among vehicle data weights of the roads in various directions or a weighted value of special vehicles and the like as reference values; and then according to the reference values, transmitting a signal to a control box of the traffic signal lamp by the control unit to operate and control to change a traffic signal lamp mode to according to the reference values, automatically or relatively increase and decrease lighting seconds of green lights of the roads in two different directions or quickly open priority pass of the special vehicles and the like so as to ensure that the traffic of the crossroad can efficiently perform automatic monitoring management during unmanned control and further achieve the effects on energy conservation, environmental protection, time conservation and emergency pass.

Description

technical field [0001] The invention relates to a method for controlling and managing signal lamps, in particular to a method for controlling and managing traffic signal lamps at intersections. Background technique [0002] At present, the traffic conditions in various regions, especially the intersections in urban areas, are almost equipped with traffic lights to control traffic. Taking a common intersection as an example, it includes two intersecting roads in different directions, such as east-west roads and north-south roads. Roads in each direction include two-way roads, such as east-west roads including east-facing roads and west-facing roads, and roads in each direction can include multi-lane roads such as two-lane roads or three-lane roads; and the traffic lights at general intersections are at least Contains two-way traffic lights of roads in different directions such as east-west and north-south roads, and utilizes a turn-by-turn interactive control mode with a time...

AI Technical Summary

Problems solved by technology

[0007] , especially, when there are special vehicles such as fire trucks, ambulances, etc. appearing in the vehicles of two different directions of roads, the traffic lights currently used, except that there are traffic control personnel on the scene and they are artificially controlled, generally cannot be controlled. Change the traffic signal light mode to quickly open special vehicles to pass first, and the driver of the front vehicle on the road often does not know that there is a special vehicle behind that is waiting for him to give up the lane, especially when the road in the direction meets I don’t know how to give way when I get to a red light, which often causes delays for special vehicles or dangers at intersections, making it impossible to efficiently monitor and manage the traffic at intersections when there is no one under control, and it is impossible to achieve emergency traffic. Efficient traffic control effect

[0008] It can be seen from the above that the current traffic lights used at intersections cannot obtain the vehicle data of roads in each direction through monitoring, such as the difference between road vehicles in each direction, the proportional relationship, or the existence of special vehicles, etc., so as to automatically control and change the traffic lights. Lighting modes such as automatically increasing or decreasing the number of seconds (passing time) of green lights on roads in different directions or quickly allowing special vehicles to pass first; when the traffic conditions at intersections cannot be efficiently controlled, other traffic conditions will be generated. Problems, such as the relative waste of gasoline, the relative increase of exhaust gas and the waste of time during traffic jams, do not meet the current energy saving and environmental protection requirements

The present invention provides an intelligent automatic monitoring method for the traffic at the intersection and its traffic lights, so as to solve the problems and shortcomings that cannot be overcome by the existing traffic lights at the intersection.
