Abstract

The aim of this study was to demonstrate the effect of the types of leading and following vehicles on the inter-vehicle gap between the front of a driver’s vehicle and the rear of the leading vehicle. Data (n = 7,370) were obtained from naturalistic observations of vehicles on a motorway. Although we anticipated that the following vehicle drivers would leave a larger gap when the leading vehicle was large, this hypothesis was not supported. In fact, heavy vehicle drivers tended to keep a greater inter-vehicle gap than passenger car drivers. These results were discussed by comparing the observed data with actual data in motorway accidents.
