Abstract
A cost-effective system provides reliable location information for locating a vehicle tied to a guideway. Reference markers are mounted to the guideway and scanning devices are disposed in the vehicle and generate at least one output signal when they pass a reference marker. The scanning devices are formed from several individual sensors which are extended in the driving direction with an average scanning length equal to or greater than a distance between neighboring reference markers.
