Abstract (en)
[origin: EP0902404A2] The method involves using fixed detectors to form local detection cross-sections for the detection of traffic-related measurement values. The values are pre-processed by local computers and standardised to a defined data format, aggregated and wirelessly passed to a superior data processing system. The fixed detectors are positioned at junctions, nodes and similar road points. The density of the fixed detectors in each area depends on the estimated traffic density.
