LTE-V2X-based internet of vehicle road traffic signal control system

Abstract

The invention provides an LTE-V2X-based internet of vehicle road traffic signal control system. The internet of vehicle road traffic signal control system comprises a road traffic signal machine, a road traffic center signal control platform, a vehicle-mounted OBU, a traffic state detector and a V2X internet of vehicle service platform, wherein the vehicle-mounted OBU is installed on an intelligent networking automobile; the vehicle-mounted OBU, the V2X internet of vehicle service platform and the road traffic signal machine communicate through a wireless mobile communication network and forman LTE-V2X network; the traffic state detector is connected with the road traffic signal machine; the road traffic center signal control platform is connected with the road traffic signal machine; andthe road traffic signal machine is connected with a signal lamp. The internet of vehicle road traffic signal control system can provide the real-time traffic signal state, the real-time road condition of an intersection, the surrounding traffic control, the traffic accident and other event information to social vehicles, has remarkable beneficial effects and is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of road traffic signals, in particular to an LTE-V2X-based vehicle networking road traffic signal control system. Background technique [0002] The traditional traffic signal control system, through the closed loop of sensing traffic flow, data circulation, and application, serves people, vehicles, and roads, and solves human safety, vehicle energy consumption, and road efficiency. Generally speaking, the traffic control system is relatively closed, with self-built detection equipment, using traditional sensing technology, generally coil detection, microwave, geomagnetism, video images and other vehicle-specific information. With the increase of vehicle ownership rate, the pressure on urban road traffic is increasing, and the traditional traffic signal control system can no longer meet the needs of the people for traffic safety and traffic efficiency under the increasingly saturated traffic flow conditions.
