Guide elements along paths and turns of a network emit guide signals for guiding vehicles along the paths and through the turns. Control elements, located at points in the network at which the locomotion of approaching vehicles may need to be controlled, emit control signals, such as "stop" and "start" signals. The signals are preferably various modulated and unmodulated sine waves having frequencies programmable by a system supervisor that sends itineraries to vehicles prescribing their respective travel routes, each itinerary containing at least a set of identifiers uniquely corresponding to the signals emitted along the paths and turns in a travel route. The order of the set indicates the order of paths and turns to be taken while travelling a route. A system interface, hosted by each vehicle, acquires itineraries pertaining to its host vehicle and provides path/turn information to a vehicle driver-a person or an apparatus. The interface also determines magnitude and direction of any vehicle deviation from a guide element the interface is monitoring and reports same to the driver; recognizes and reports control signals to the driver; and detects transition points at which its host vehicle should go from one path/turn to another path/turn and indicates any needed course corrections to the driver. Sensors along paths and turns detect the proximity of a vehicle or such to it and report same to the supervisor. Optionally vehicles send their respective identification codes to the supervisor via each sensor they encounter. |
