MEASUREMENT OF JOURNEY TIME LOST AT TRAFFIC SIGNALS. TWO METHODS TO MEASURE THE JOURNEY TIME LOST BY VEHICLES AT TRAFFIC SIGNALS

VERLIESTIJDMELDING BIJ VERKEERSLICHTEN. TWEE METHODEN OM DE VERLIESTIJD DIE VOERTUIGEN OPLOPEN BIJ VERKEERSREGELINGEN TE METEN

In the evaluation of traffic control by traffic signals the average journey time lost is important. The journey time lost is caused by the slowing down, waiting and accelerating of a vehicle before a bottleneck. Existing methods to measure this lost journey time are often difficult to use and not cheap. In this report a study is presented to develop measuring methods which can fulfill requirements. The working of these measuring methods is discussed and after simulation (by the flexsyt program) their reliability is tested. The first method works with a counting detector just before the stop line. Testing on the street shows that the average journey time lost is reproduced in a reliable way. The second method works with the red and green times as input data. This method was not tested on the street but compared with the first method. The second method did not provide reliable figures for journey time lost, but does give an accurate enough impression of it. (TRRL)
