Abstract
This paper utilizes the traffic flow model of car-following to study the movement of two consecutive vehicles travelling in the same lane of a freeway. The car-following models defined the speed and headway of a moving vehicle but have not analyzed their relation. In the proposed block-moving approach, the following vehicle is considered as a moving object obstructed by another one moving in the same direction. In that, the correlation between the speed and headway of the following vehicle, which are recorded discretely in real time by instruments installed on the following vehicle, is analyzed and processed to avoid collisions caused by the following vehicle. Additionally, the following vehicle must react accordingly to the behaviors of the leading vehicle by increasing or decreasing speed to a desired speed. This study proposed a methodology to effectively determine how much engine or brake force should be made to achieve the desired speed.
