Research on the Surveillance Technology and the Comprehensive Management Network System Using the Optical Fiber About a Road Management System

In recent years, IT (Information Technology) has been utilized in various fields of civil engineering. Especially, trials have been made to utilize optical fibers as sensors to measure strain of civil engineering structures, ground deformation, temperature, etc., and they have been installed for measuring in road structures and civil engineering structures including tunnel, river, and cut-slope structures. In order to make such optical monitoring systems of civil engineering structures more general and organic systems, it would be effective to combine them with such comprehensive systems as ITS. We investigate checking systems utilizing GIS technology, etc. that can process and analyze an enormous amount of data in real time and also investigate the construction of general monitoring systems of road facilities which can perform thorough management from monitoring to maintenance utilizing information technology networks.
