System and method for bus left-turn regulation and control of left-turn and straight common signal lamp crossroad

Abstract

The present invention provides a system for bus left-turn regulation and control of a left-turn and straight common signal lamp crossroad. The system comprises: a vehicle signal sender arranged on the bus which turns the left at the crossroad; and signal receivers arranged at four corners of the crossroad. The vehicle signal sender is configured to emit left-turn signals when the bus turns left; the signal receivers are connected with a traffic light controller of the crossroad and configured to receive the left-turn signals and send the left-turn signals to the traffic light controller, and the traffic light controller controls the state of the traffic light according to the current state of the traffic light. The system and method for bus left-turn regulation and control of the left-turn and straight common signal lamp crossroad can improve the left-turn efficiency of the bus at the crossroad to the utmost extent so as to reduce the influence on the straight vehicles to a minimum.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a left-turn control system and method for buses at a left-turn and straight-going shared signal light intersection. Background technique [0002] Traffic congestion has always been one of the urban problems. On this basis, the society is increasingly advocating the priority of public transportation and the efficient passage of motor vehicles. Therefore, most cities have set up bus lanes. The bus lane is generally located on the far right side of the road, and is separated from other motor vehicle lanes in the same direction by road curbs or railings. However, because some road infrastructure constructions have not kept pace with social development, many intersections in cities, especially two-way four-lane intersections, still use the same status signal lights for left-turn vehicles and straight vehicles. figure 1 , when you are about to enter the ...
