METHOD AND DEVICE FOR THE DISTINCTION OF VEHICLES OF DIFFERENT CONSTRUCTIONS IN ROAD TRAFFIC

摘要

1. A method of distinguishing between vehicles of different types in traffic by means of a single induction loop (1) let into the carriageway, by evaluating the loop detuning (DELTA L) exceeding a preset response value, characterized in that the relative positions (tx ; tp -x ) in time, relative to the beginning and end of the total period (tp ) during which the preset response value is exceeded, of the first maximum of the loop detuning reached during the passage of a vehicle are measured quantitatively and are used as a distinguishing criterion.
