Abstract
A vehicle control system and method wirelessly communicate from at least one wireless transmitter positioned proximate a route crossing to a wireless receiver of a vehicle via a wireless wayside transceiver. The system and method communicate an indication of whether the route crossing is clear for passage of the vehicle through the route crossing. The system and method receive the indication by the wireless transmitter and using the vehicle receiver. A vehicle controller or an operator of the vehicle can determine whether it is safe for the vehicle to travel through the route crossing based on the indication received by the vehicle receiver from the portable transmitter. The vehicle can then be operated based on the determination.
