RESEARCH ON THE SAFETY DISTANCE MODEL BASED ON CAR-CAR COMMUNICATION

摘要

The Safety Distance Model (SDM) is one key research of the collision prevention system.The paper presents the improved SDMs based on the development of car-car communicationtechnology characterized of its on-time measurement and communication. The research isfocus on analyzing SDMs of the vehicle fleet driving in single lane under car-following status.By considering both the braking theory and driver prediction model, the absolute and relativeSDMs are achieved to support decision-making information in corresponding drivingconditions. The comparative analysis with tradition four SDMs confirms that the proposedmodels are able to increase the efficiencies of the vehicle collision prevention system,increase the utilization rate of the road on promise of ensuring the driving safety.
