Abstract
A system and method of determining a vehicle location where roads have different elevations and at least partially overlap. The method carried out by the system includes: receiving a plurality of Global Navigation Satellite System (GNSS) satellite signals at a vehicle; determining a vehicle location and a vehicle velocity including an up velocity based on the received GNSS signals; identifying a plurality of roads, within a range of the vehicle location, at least one of which has a different elevation than the other road(s); and selecting at least one of the plurality of roads within the range based on the up velocity component.
