1. A computer-implemented method, comprising:
receiving, by a server from a vehicle, navigation information associated with the vehicle;
determining, by the server, one or more predicted positions associated with the vehicle based on the navigation information, wherein the one or more predicted positions corresponds to a plurality of road segments;
acquiring, by the server from a data store storing map data, speed limit information for one or more groups of road segments included in the plurality of road segments;
determining, for each group of the one or more groups of road segments, that the group of road segments share a common speed limit;
generating, by the server, one or more candidate map regions associated with the vehicle from the one or more groups of road segments; and
transmitting, by the server to the vehicle, the one or more candidate map regions;
wherein the one or more candidate map regions are usable by the vehicle to provide speed limit information to a driver of the vehicle.
