This paper introduces a novel application of fiber microbending sensor to monitor the highway vehicles, i.e. overtime pull-over vehicles. Precise locations and durations of the overtime pull-over vehicles can be detected and alarms can be sent to highway administrators. Highway administrators can use these data to maintain the traffic order, secure the passengers and enforce the law. The sensor is designed based on fiber microbending effect and optical time-domain reflectometry method is utilized to generate, collect and process the optical signals. The experiment is designed to simulate the highway shoulder with vehicle parking on it. Different vehicle weight-induced fiber microbending losses are detected and measured. By the optical time domain reflectometry technique, the precise locations of pull-over vehicles have been obtained.
