Study on Safety Distance Model of Fleet based on Vehicle Communication

摘要

The Safety Distance Model (SDM) is a key component of the collision prevention system. The SDM research rarely considers vehicle fleet as the research target, as the traditional SDMs only focus on the communication between two vehicles. This paper presents the updated SDMs established on vehicle communication technology characterized by on-time measurement and communication. The research focus is on analyzing vehicle queuing in single lanes which are under car-following status. The absolute and relative SDMs accounting for both the braking theory and driver prediction model, are obtained, which could provide decision-making information to driver. The proposed SDMS are proved to be able to increase the efficiency of vehicle collision prevention.
