Distance-time detection for road users involves using cellular radio network, whereby central station knows instantly in which radio cell active terminal is located and indicates each handover between cells

摘要

The method involves using a cellular radio network, whereby a central station for the distance-time determination knows instantly in which radio cell an active terminal is located and indicates each handover between cells. The terminal must be continuously carried on board, the central station indicates time/date and the handover together for each terminal.
