Traffic monitoring using fiber optic grating sensors on the I-84 freeway and future uses in WIM

Abstract

Blue Road Research has demonstrated the use of fiber optic Bragg grating sensors in roads and highways to develop traffic sensors that could count and classify traffic usage on roadways, providing statistical information for maintenance, safety, and growth. This paper reviews the progress by Blue Road Research that led to installation of traffic sensors on the I-84 freeway and outlines the benefits of developing a fiber optic weigh-in-motion sensor.
