1. A method, comprising: receiving, by an on-board computer in a selected maintenance vehicle, at least one of weather information from a weather service provider (“WSP”) server, automatic vehicle locating system (“AVL”)-collected information from an AVL server, and information collected locally by the on-board computer; accessing, by the on-board computer, a material performance specification for at least one treatment material on-board the selected maintenance vehicle; and determining, based on the at least one of weather information, AVL-collected information, and locally-collected information and the material performance specification, a treatment recommendation to be followed by the selected maintenance vehicle for a selected roadway segment and/or route; and wherein the treatment material is at least one of an anti-icing agent and a de-icing agent, wherein the treatment recommendation comprises at least one of treatment material type, composition, amount, concentration, and application rate, wherein the at least one of weather information, AVL-collected information, and locally-collected information is AVL-collected information, and wherein the AVL-collected information comprises historic maintenance vehicle parameters, wherein said historic maintenance vehicle parameters are taken from a historic maintenance vehicle different from the selected maintenance vehicle and for the selected roadway segment and/or route, and wherein said historic maintenance vehicle parameters include at least one of traffic level, road condition, roadway surface temperature, historic maintenance vehicle speed, historic maintenance vehicle engine revolutions-per-minute, weather condition, historic maintenance vehicle snow plow setting, treatment material type applied, treatment material mixture applied, treatment material application rate, treatment material amount applied, time of treatment application, a video image of the selected roadway segment and/or route, roadway friction measure, thermal imaging information, infrared imaging information, solar energy level, and an earliest dispatch time for a next available maintenance vehicle (other than the selected maintenance vehicle or the historic maintenance vehicle) to treat the selected roadway segment and/or route.
