Abstract

A closed-loop accident prevention system and method for long downhill highways, which can solve the technical problem that traffic accidents are easily caused when long downhill highways are long. It is installed on the long downhill section of the expressway, including the front-end subsystem that encodes the collected traffic information and then transmits it to the back-end management subsystem through the network. The back-end management subsystem realizes real-time event preview, vehicle statistics, data query, and traffic parameters. Information statistics and information release; the front subsystem includes the bayonet speed measurement system and the guidance release system set at the starting point of the downhill, the single point speed measurement system and the digital voice broadcast system set in the slope, and the event detection system set at X distance before the bottom of the slope , Set the bayonet speed measurement system at the bottom of the slope. The invention realizes the real-time automatic detection of vehicle speed and flow in the long downhill section, and feeds back to the driver, realizes vehicle-road coordination, and meets the development needs of the intelligent transportation system.

Description

technical field [0001] The invention relates to the technical field of traffic safety management and control, in particular to a closed-loop accident prevention system and method for long downhill highways. Background technique [0002] Mountainous highways, due to natural conditions such as terrain, geology, hydrology, climate and environment, and investment constraints, often have long and downhill road sections. The accident rate and death rate of this part of the road section are several times or even dozens of times that of ordinary road sections. Through the investigation of the traffic accidents on the long and downhill highways in mountainous areas, it is found that brake failure is the main cause of traffic accidents, followed by speeding, and large and medium-sized trucks are the main types of accidents. On long downhill roads, the brakes decelerate and brake continuously for a long time, resulting in thermal fading of the braking performance of the vehicle and fai...
