Intelligent intersection intelligent traffic signal lamp system and vehicle-road cooperation intelligent traffic signal lamp

Abstract

The invention provides an intelligent intersection intelligent traffic signal lamp system and a vehicle-road cooperation intelligent traffic signal lamp. A C-V2X module in the signal lamp is in communication connection with a signal lamp control module and a communication module through serial ports; the C-V2X module is used for outputting a control instruction to the signal lamp control module and controlling the signal lamp control module to execute a lamp control command according to the control instruction, and used for acquiring a real-time traffic event of a local intersection from the cloud control platform through the communication module, and pushing the real-time traffic event and the current phase timing information. According to the vehicle-road cooperation intelligent traffic signal lamp, a traditional signal machine and a signal lamp on a lamp pole can be combined, the function of vehicle-road cooperation can be fused through a C-V2X module, normal output of a phase scheme can be ensured, real-time traffic events of a local intersection and current phase timing information can be pushed, dynamic information interaction with vehicles on the front road is realized, and the traffic operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination information transmission, in particular to an intelligent intersection intelligent traffic signal light system and a vehicle-road coordination intelligent traffic signal light. Background technique [0002] With the development and progress of science and technology, safer, more efficient and more convenient travel will be the requirements of the future, while traffic safety, traffic congestion and environmental pollution are the three major problems facing the current transportation field, and they must be solved for future smart travel question. As the development trend and direction of the future automobile industry, intelligent networked vehicles have received great attention from the state in recent years. The roadmap for China's intelligent networked vehicles also clearly states that vehicles and infrastructure are the two verticals of intelligent networked vehicles. At pr...
