TRAVEL TIME MEASUREMENT USING INFRARED VEHICLE DETECTORS

Japan's Universal Traffic Management System (UTMS) project aims to transmit detailed traffic information to individual drivers using infrared vehicle detectors. This paper describes an experiment to verify the validity of calculated travel times by matching vehicle identification numbers which are recieved as up-link information from infrared vehicle detectors. In particular two aspects were considered: a) the effects of the composition of the experimental course section and passage of time in calculating travel time and b) the effect of the ratio of vehicles equipped with in-vehicle units. For the covering abstract see IRRD 880251.
