Abstract
Apparatus for transmitting location based messages from vehicles (10) to a stationary infrastructure (14, 16), including at least one transponder (20) installed on a vehicle (10), at least one stationary base (18) in the form of a transceiver for exchanging signals with the transponder (20), a device (22) for measuring run times of the signals and for calculating the distance between the base (18) and the transponder (20), and an evaluation system (24) for evaluating the messages contained in the signals from the transponder (20) on the basis of the measured distance.
