Abstract
A system and a method for monitoring route devices in a transportation network includes one or more processors to receive sensed traffic control device information from first vehicle systems in a transportation network formed from interconnected routes. The sensed traffic control device information indicates states of traffic control devised at intersections between the routes in the transportation network. The one or more processors determine whether the sensed traffic control device information conflicts with stored traffic control device information stored in a database accessible by the one or more processors. The one or more processors send one or more bulletins to one or more second vehicle systems to change movement of the one or more second vehicle systems responsive to determining that the sensed traffic control device information conflicts with the stored traffic control device information.
