Exploring heavy vehicles car-following behaviour

This work investigates the car-following behaviors of heavy vehicles and. Furthermore, a comprehensive comparison between heavy vehicles and passenger cars is presented. Freeways are designed to facilitate the flow of traffic including passenger cars and trucks. The impact of these different vehicle types is not uniform, creating problems in freeway operations and safety particularly under heavy demand with a high proportion of heavy vehicles. There have been very few studies concerned with the traffic behavior and characteristics of heavy vehicles in these situations. This study draws on extensive data collected over a long stretch of freeway using videotaping and surveys at several sites. The collected data were firstly used to study the interaction between heavy vehicles and passenger cars. The results showed a significant difference in the following behavior of heavy vehicles compared to other vehicles.
