Abstract
Each vehicle of a transport system is provided with a short range transmitter which continuously transmits the vehicles route designation in digitally encoded form, preferably by short wave radio. Some or all stops are each provided with a short range receiver decoder and display means. All transmitters and receivers operate on the same frequency. The receiver stores codes for all routes with stops at the receiver location, matches encoded signals it receives with the stored codes and displays the matched designation.
