摘要

A traffic monitoring system comprises at least one sensor station ( 2 ) and an interferometric interrogation system ( 9 ); wherein the at least one sensor station ( 2 ) comprises at least one optical fiber sensor ( 5 ) deployed in a highway ( 1 ); and wherein the interferometric interrogation system ( 9 ) is adapted to respond to an optical phase shift produced in the at least one optical fiber sensor ( 5 ) due to a force applied by a vehicle passing the at least one sensor station ( 2 ).
