1. A server system for providing data to at least one mobile device, the server system comprising:

  • a memory storage; and

    a processing unit coupled to the memory storage, wherein the processing unit is operative to;

    obtain data that represents the variation of a speed modification parameter as a function of location at a plurality of different times, wherein the speed modification parameter is representative of an expected modification to an average speed of travel due to weather or other environmental conditions; and

    process the data to generate at least one data set for transmission to a mobile device, the generating comprising adding, to each data set, contour data for at least one contour that represents a boundary of a respective area for which the speed modification parameter has substantially a same value, the contour data comprising coordinates of vertices and/or edges of a polygon that represents the at least one contour, and the contour data configured to be used by the mobile device to compute, for the at least one contour, the respective area in which all of a plurality of road segments are to have a corresponding average speed modified using a same speed modification parameter; and

    transmit the generated contour data to the mobile device;

    a communications channel for transmitting the at least one data set to the mobile device;

    wherein the communications channel is operable to receive time and location data from the mobile device identifying at least a time and one location and the processing unit is configured to obtain the at least one data set in dependence on the identified time and location.
