  • Abstract
    Discusses equipment which can optically sense moving vehicles, and discriminate their sizes. Based on a conceptual consideration on size discrimination, a hardware implementation using a SnO2-Si photocell array and simple electronic circuits is made. The developed equipment can separately count three sizes of moving vehicles along a road.
