Modeling of safe driving distances is one of the most important topics in collision prevention analysis. This paper presents an improved safe distance model (SDM) that is based on vehicle-to-vehicle communication technology. The technology enables on-time data collection as well as real-time intervehicle communication. A tube-like highway scenario in which vehicles enter at one end and exit at the other is presented to demonstrate the application of the SDM. By incorporation of both braking theory and a driver behavior prediction model, absolute and relative SDMs are developed to provide decision-making information to drivers in response to changing traffic conditions. The comparative analysis with four traditional SDMs confirmed that the proposed model describing the characteristics of vehicle-to-vehicle communication was able to improve the efficiency of vehicle collision prevention systems and increase road use, as well as ensure safe driving.
