Abstract

Vehicles travel along roads and make measurements of signals from electromagnetic signal sources to either side of the road. The side of the road of each signal source and the variation in the strength of the signals from each signal source along the road, or the sides thereof can therefore be determined. Data concerning the side of the road on which each signal source falls can be used to improve or interpret pre- existing data concerning the position of signal sources.
