Abstract

The invention discloses a reversible lane changing system and method by virtue of compass angle measurement and ultrasonic distance measurement. The reversible lane changing system comprises a remotecontrol center, a traffic light background data server, a road section control base station and lane changing robots. When the change of a reversible lane is required, the remote control center sendsa reversible lane changing signal to the road section control base station in real time; the road section control base station sends walking command control signals to the corresponding lane changingrobots by means of wireless data transmission; and the lane changing robots perform corresponding movements when receiving respective walking commands and feed position information back to the road section control base station in real time. The reversible lane changing system and method by virtue of compass angle measurement and ultrasonic distance measurement is capable of realizing the automaticchange of the reversible lane according to requirements, realizing the real-time change of the urban traffic road network through the combination with the traffic light background data server and theuse of big data, coping with the change of road requirements due to traffic accidents, variation of traffic flows, bad weather and other factors at any time, and realizing the automatic control of the reversible lane.

Description

technical field [0001] The present invention relates to the technical field of tidal lanes, and more specifically, relates to a system and method for changing tidal lanes by using compass angle measurement and ultrasonic distance measurement. Background technique [0002] Cars have brought great convenience to human travel, but with the rapid increase in the number of cars, traffic congestion is becoming more and more serious. Although the government continues to build roads and urban expressways, the growth rate of roads is far lower than the growth of the number of cars. In order to solve this problem, the government has invested more and more funds and energy in the development of intelligent transportation systems in recent years to improve the efficiency of road traffic and alleviate traffic congestion. [0003] The "tidal phenomenon" of traffic is one of the important reasons for urban traffic congestion. Every morning, the traffic flow in the direction of the city is...
