QUEUE DETECTION USING LOOP DETECTORS

HET OPSPOREN VAN FILES MET BEHULP VAN LUSDETECTOREN

Queues on motorways which build up quickly are not only A nuisance to the motorist, but are also a source of sometimes serious accidents. The author describes a system developed by the technical university of delft which identifies vehicles through loop detection. The identifying data which a vehicle transmits are so complete that they constitute A so-called signature. Loop nr 1 sends this message to loop nr 2 including the estimated time of arrival of the vehicle. Either the whole signature is compared in the two loops or only the length of the vehicle. A disadvantage of the latter is the fact that many vehicles are in the same length category. As soon as some subsequent irregularities in the traffic stream are detected (rather than isolated ones which would cause false alarms) the central computer may organize a range of measures to minimize the adverse effects of whatever caused the disruption.
