Apparatus, method, and non-transitory computer-readable medium for determining vehicle characteristics based on vibrations sensed using optical fiber

Abstract

Provided is a travelling vehicle detection apparatus including: a measurement unit that that measures a continuous physical quantity at a predetermined place using an optical fiber sensor laid along a road, a detection unit that detects a temporal change pattern of the physical quantity from a measurement result of the measurement unit, and a determination unit that determines whether there is a travelling vehicle based on the change pattern of the physical quantity. Here, the physical quantity is a vibration intensity, and the change pattern is a change in absolute value, a change in difference, a change in ratio, or a change in graph shape.
