Abstract

Accurate knowledge of vehicle speeds and headways on traffic networks is a fundamental part of transport systems modelling. Video and recently developed automatic data-extraction (image processing) techniques have the potential to provide a cheap, quick, easy, and accurate method of investigating traffic systems. This paper presents two studies that use video-based equipment to investigate the character of vehicle speeds and headways. Investigation of headways on freeway traffic allows the potential of this technology in a high-speed environment to be determined. Its application to the study of speeds in parking lots enabled its usefulness in low-speed environments to be studied. The data obtained from the video was compared to traditional methods of collecting headway and speed data.
