Cooperative vehicle infrastructure system-based intersection vehicle right turning guidance system and guidance method thereof

Abstract

The invention relates to a cooperative vehicle infrastructure system-based intersection vehicle right turning guidance system and a guidance method thereof. The guidance system includes a road-side device, a monitoring center and at least one vehicle-mounted device. When a vehicle entering an intersection communication range of the road-side device, a vehicle-mounted main control module performs analysis and judgment according to the static information of the vehicle, vehicle operating location information, vehicle driving direction, vehicle speed and traffic status information of an intersection where the vehicle is located; if judging that conflict between a motor vehicle and a non-motor vehicle or conflict between motor vehicles will occur in the future, the vehicle-mounted main control module analyzes safe vehicle speed required by right turning and transmits the safe vehicle speed to a prompt module and a vehicle speed control module; a driver will be prompted with the safe vehicle speed required by right turning through the prompt module; and the vehicle-mounted main control module monitors whether the vehicle drives at the safe vehicle speed; and if the vehicle-mounted main control module monitors that the vehicle does not drive at the safe vehicle speed, the vehicle speed control module will automatically control the speed of the vehicle.

Description

technical field [0001] The invention belongs to vehicle-road coordination and safety control technology in an intelligent transportation system, and relates to a right-turn guidance system for vehicles at an intersection based on vehicle-road coordination and a guidance method thereof. Background technique [0002] There is no special right-turn phase in most signalized intersections in the city, and interference and conflicts between right-turning vehicles and adjacent straight vehicles, pedestrians crossing the street, and non-motorized vehicles are very common, which seriously affects the traffic safety and traffic efficiency of the entire intersection. . Previous studies have proposed to set up special right-turn phases to solve the safety hazards caused by vehicles turning right, but for intersections with relatively small traffic flow, it will inevitably cause waste of resources. With the rapid development and application of electronic information and wireless communi...

Problems solved by technology

[0004] The currently disclosed devices for assisting vehicle driving safety at road intersections are all early warning devices, which have a single function and cannot fundamentally avoid the occurrence of traffic accidents, making it difficult to achieve real driving safety.
