City road traffic crossing in-vehicle traffic information lamp early warning method and system based on Internet of vehicles

Abstract

The invention discloses a city road traffic crossing in-vehicle traffic information lamp early warning method and system based on Internet of vehicles. The method is based on the wide application of a wireless transmitting terminal, and employs a wireless transmit-receive module for range finding; a wireless receiving terminal is provided with a directive antenna so as to limit a reading scope. Meanwhile, based on the installation position of a wireless transmitting terminal, range finding is more accurate. Comprehensively considering whether a current state is red light or green light, and whether vehicles exist in front, the method provides early warning information for current vehicles, allowing the current vehicles to safely and rapidly pass through a crossing. The system comprises a traffic information collecting and transmitting module, a vehicle wireless transmit-receive module, a self vehicle information collection module, a lane detection module, a vehicle display module, an acousto-optic alarm module, a power supply module and a data processing module. A whole system has a simple structure, is convenient to use, and provides accurate determination and early warning information for vehicle owners based on a provided algorithm.

Description

technical field [0001] The invention belongs to the field of traffic control, in particular to an early warning method and system for traffic information lights in vehicles at urban road traffic intersections based on Internet of Vehicles. Background technique [0002] Nowadays, the number of automobiles in my country is increasing rapidly, followed by traffic congestion and frequent traffic accidents, which not only affect the urban air quality, but also cause waste of time and resources. Due to strong sunlight or foggy weather, it is impossible to directly observe traffic lights at intersections. If a vehicle-mounted traffic light display device can be designed to effectively help drivers understand the status of traffic lights at intersections ahead, the incidence of vehicle accidents will be greatly reduced. [0003] After searching the literature of the prior art, it is found that Chinese patent application number CN105035090A provides a trajectory prediction control me...
