Abstract
A system includes a vehicle control system, a friction modification unit, and a friction management module. The vehicle control system is configured to obtain a trip plan for the vehicle. The trip plan is based on one or more characteristics of a trip of the vehicle along a route in a transportation network, characteristics of the vehicle, or characteristics of the route along which the vehicle travels. The trip plan designates one or more tractive operations or braking operations. The friction modification unit is configured to modify a friction characteristic of a surface of the route as the vehicle travels on the route. The friction management module is configured to direct the friction modification unit to modify the friction characteristic of the surface of the route based on the trip plan.
