1. A method for determining path specific rolling resistance, comprising:
receiving, from a first source, first rolling resistance data of a first set of more than one road surface portions of a corresponding first set of times;
receiving, from a second source, second rolling resistance data of a second set of more than one road surface portions of a corresponding second set of times;
determining, using any of the first rolling resistance data and the second rolling resistance data, a path specific rolling resistance for a given path comprising more than one of the road surface portions selected from the first and second set of road surface portions;
providing at least one target vehicle with the path specific rolling resistance or a derivative of the path specific rolling resistance; and
directing route choices for the target vehicle using the rolling resistance information.
