Abstract
Heavy vehicles are significantly longer and heavier than passenger cars and consequently have quite different acceleration and braking capabilities. Heavy vehicle manoeuvres are therefore likely to influence drivers' vehicle-following behaviour differently to cars. Heavy vehicles can also influence the behaviour of drivers of other vehicles while following a heavy vehicle. This paper used data obtained from the Interstate-80 in California to show the impacts of the presence of heavy vehicles in a traffic stream on the vehicle-following behaviour of car and heavy vehicle drivers. Four vehicle-following combinations, based on the vehicle classes of the leader and subject vehicle, are considered in this study. These combinations are car-car, car-heavy vehicle, heavy vehicle-car and heavy vehicle-heavy vehicle. The study analyses the space and time headways, driver's reaction time and vehicle acceleration for the four vehicle-following combinations. The results highlight the different behaviour of the vehicles in the four combinations. In summary, the presence of heavy vehicles results in a larger headways, longer reaction time and smaller variation in acceleration variation during vehicle-following behaviour. Further research is required to determine the underlying reasons for these differences.
