A method of communicating road treatment data to a plurality of control devices (200-1, 200-2, 200-n) each associated with a road treatment vehicle (300-1, 300-2, 300-n), comprising: determining, at a first computer, road treatment data comprising route information indicative of a route around a road network to be followed by one of the road treatment vehicles (300-1, 300-2, 300-n), and treatment level data (608-a, 608-b) indicative of an amount of treatment material to be applied to one or more portions of the route by the road treatment vehicle (300-1, 300-2, 300-n), wherein the route information comprises map data and route data, the route data indicating the route around the road network to be followed by the road treatment vehicle and the map data indicating a road network in a geographical region corresponding to the route data and comprising at least one topographic identifier indicating a feature of the map data, wherein the control device is configured to automatically select the road treatment data; communicating wirelessly the road treatment data to each of the plurality of control devices (200-1, 200-2, 200-n); configuring the received road treatment data at each of the plurality of control devices (200-1, 200-2, 200-n) for selection by a user; receiving, at a control device amongst the plurality of control devices (200-1, 200-2, 200-n), a user input indicative of selected road treatment data, and outputting an indication of the route around the road network comprised within the selected road treatment data, through an interface unit of the control device, receiving, by a control device amongst the plurality of control devices (200-1, 200-2, 200-n), a current location of a respective road treatment vehicle; identifying, by the control device, at least one topographic identifier corresponding to the current location of the respective road treatment vehicle; determining, by the control device, whether the at least one topographic identifier encountered by the respective road treatment vehicle, is comprised within the route data; and, if a number of consecutively encountered topographic identifiers comprised within the route data is greater than a predetermined threshold, automatically selecting, by the control device, road treatment data to be followed by the respective road treatment vehicle, based on the at least one topographic identifiers. determining, at a first computer, road treatment data comprising route information indicative of a route around a road network to be followed by one of the road treatment vehicles (300-1, 300-2, 300-n), and treatment level data (608-a, 608-b) indicative of an amount of treatment material to be applied to one or more portions of the route by the road treatment vehicle (300-1, 300-2, 300-n), wherein the route information comprises map data and route data, the route data indicating the route around the road network to be followed by the road treatment vehicle and the map data indicating a road network in a geographical region corresponding to the route data and comprising at least one topographic identifier indicating a feature of the map data, wherein the control device is configured to automatically select the road treatment data; communicating wirelessly the road treatment data to each of the plurality of control devices (200-1, 200-2, 200-n); configuring the received road treatment data at each of the plurality of control devices (200-1, 200-2, 200-n) for selection by a user; receiving, at a control device amongst the plurality of control devices (200-1, 200-2, 200-n), a user input indicative of selected road treatment data, and outputting an indication of the route around the road network comprised within the selected road treatment data, through an interface unit of the control device, receiving, by a control device amongst the plurality of control devices (200-1, 200-2, 200-n), a current location of a respective road treatment vehicle; identifying, by the control device, at least one topographic identifier corresponding to the current location of the respective road treatment vehicle; determining, by the control device, whether the at least one topographic identifier encountered by the respective road treatment vehicle, is comprised within the route data; and, if a number of consecutively encountered topographic identifiers comprised within the route data is greater than a predetermined threshold, automatically selecting, by the control device, road treatment data to be followed by the respective road treatment vehicle, based on the at least one topographic identifiers.
