    An automatic vehicle monitoring (AVM) system employing magnetic signposts imbedded in the roadway has been designed and tested. It has been augmented by a technique for detecting turns of approximately 90°. Combined in a hybrid AVM system, the two techniques provide great accuracy and high reliability with lower signpost density than a signpost system without turn detection. In this AVM syste...
