Abstract: A route management system comprising dispatch operations; fleet management software; at least one onboard computing device; weather data; and a weather-fleet comparison method. More specifically, the system collects information about a place of departure, a place of arrival, a scheduled route, scheduled stops, and a weather forecast; compares the predicted weather forecast to the scheduled route; displays the weather forecast information to a driver and/or a dispatcher; determines if a new route or departure time should be scheduled; and, if a new route should be scheduled, displays the new route or departure time to the driver and/or the dispatcher.
