Abstract (en)
[origin: EP0902405A2] 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 standardized to a defined data format, aggregated and wirelessly passed to a superior data processing system. The transferred data are processed using at least two redundant, mutually different and independent computation methods to determine route-related traffic information.
