Research on Deceleration Early Warning Model Based on V2X

In order to reduce the incidence of forward collision in traffic accidents, this paper analyzes the dynamics and kinematics of vehicle braking process and car following process, and studies the application of V2X technology in the vehicle networking system, and proposes a research method of multi road adaptive early warning model based on V2X technology. Based on the vehicle road cooperation technology, this method establishes a vehicle anti-collision early warning model with time, position, speed, vehicle spacing and braking distance as parameters. Combined with the actual situation, several application scenarios are designed, including vehicle forward collision warning, intersection approaching light changing warning, intersection blind spot warning, curve deceleration warning and vulnerable traffic participants warning, and detailed technical reference routes are given.
