Influence of deceleration intention indicating system of forward vehicle on driver behavior

Abstract

This paper discusses a way to detect the driver's intention to decelerate the vehicle in a car-following situation. In the present study, a field observation of a car driving and an experiment were conducted. In the field observation, the data were collected for analyzing a driver's maneuvering of the accelerator and brake pedals in order to design a system that can detect the driver's intention to deceleration. The method based on the covering brake pedal found to be highly reliable. In the experiment, an investigation using an experimental vehicle and a test course was conducted to evaluate the influence of the proposed system on the driver behavior. The experimental results showed that the system was effective in improving the driver's accelerator release time (ART) and the brake onset time (BOT). © 2013 Springer-Verlag Berlin Heidelberg.
