Abstract
An automated vehicle protection system is provided comprising a guideway (20), a vehicle (10), a guideway loop antenna (21), and transponders (41a, 41b), mounted on the vehicle (10). Means (24, 25) are provided, couple to the guideway loop antenna (21), for receiving a signal from the vehicle (10) and generating an inhibit signal in order to inhibit vehicle movement in a section of the guideway (20). The inhibit signal may be passed to a circuit associated with another guideway loop antenna (22, 23) to control transmission of a signal from this other guideway loop antenna (22, 23).
