Application of inductive loops as wheel detectors

This article presents the findings of model and field research into narrow inductive loop used as vehicle wheels detector in normal traffic conditions. The efficiency of the solution was compared with that of strip, polymeric piezoelectric detectors. The findings confirmed that narrow inductive loops can be successfully applied as wheel detectors.

► The inductive loop was applied as the wheels detector.
► Solution allows counting the wheels and measuring distances between axles.
► The uncertainty is comparable with that obtained from piezoelectric detectors.
► The vital advantage of presented solution is its ability to detect lifted axles.
