VEHICLE MANAGEMENT SYSTEM

Abstract:

A vehicle management system communicates with monitor devices coupled with a path control device at an intersection between route segments. The path control device switches positions to connect different combinations of the route segments. The system receives signals from the monitor devices to determine which of the route segments are coupled with each other and receives an authority signal from a travel authority system that indicates which of the route segments that the vehicle is authorized to travel. The system directs the vehicle through the path control device responsive to a combination of: (a) receipt of the authority signal and (b) receipt of at least one of the monitor signals or failure to receive one or more of the monitor signals.
