Abstract
A control system includes an onboard controller, a location determination system, and a speed sensor. The controller identifies a designated area along a route that includes a downhill section, an airflow restricted area, a banked section, a section to be cleaned, an adverse environmental area, an adverse vehicular condition area, and/or a section where travel is restricted. The designated area is associated with an operating rule that requires the vehicle to travel at least as fast as a lower speed limit. The location determination system monitors actual locations of the vehicle as the vehicle travels along the route. The speed sensor obtains speed data representative of an actual velocity of the vehicle. The controller restricts control of the vehicle such that the actual velocity of the vehicle is at least as fast as the lower speed limit of the designated area when the vehicle is in the designated area.
