Abstract (en)
[origin: EP0908861A2] The method involves forming local detection cross-sections using fixed detectors which detect 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 inputs to the processing procedure are at least traffic speed and volume. The output data can be at least the travel time and traffic density at a detection cross-section. The data can be finally processed using an expanded complex processing technique to determine traffic information related to routes.
