This paper describes the measuring procedure employed in the fully automated traffic information centers, in which the congestion degree is calculated by automatically checking the signalised intersection queue length with vehicle detectors. In this method, queues can be measured by installing one or two vehicle detectors on the incoming path of an intersection and by reading out the time of occupancy by the detectors. Since several typical values of the time of occupancy can be obtained depending on the relative distance between the position of the vehicle detector installed several hundred meters upstream from the stop line and the position of the end of the queue, a waiting queue-time of occupancy curve can be obtained.
