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.

Systems and methods for improved operations of ski lifts increase skier safety at on-boarding and off-boarding locations by providing an always-on, always-alert system that “watches” these locations, identifies developing problem situations, and initiates mitigation actions. One or more video cameras feed live video to a video processing module. The video processing module feeds resulting sequences of images to an artificial intelligence (AI) engine. The AI engine makes an inference regarding existence of a potential problem situation based on the sequence of images. This inference is fed to an inference processing module, which determines if the inference processing module should send an alert or interact with the lift motor controller to slow or stop the lift.

A vehicle control system is provided for controlling adhesion of wheels to a route surface. The control system includes one or more processors configured to determine adhesion values representative of adhesion between the wheels of a vehicle and the route surface based on angular speeds of the wheels. The one or more processors are configured to generate a target slip value for the wheels that are coupled with at least two different axles of the vehicle by processing the adhesion values and modifying the target slip value continuously in time to maximize an average value of the adhesion values of the wheels. The one or more processors also are configured to control a torque applied to at least one of the axles based on the target slip value.
