| Summary: | 碩士 === 國立中央大學 === 土木工程學系在職專班 === 102 === In recent years, Directorate General of Highways, MOTC actively constructs publishing platform for immediate traffic information in provincial highway, and establishes various traffic control facilities in accordance with different types and regional characteristics of provincial roads, expressway and a number of tunnels by selecting easy congestion road, easy accident of road or road to hot attractions, providing administrative unit in traffic control center with information through the images to determine many traffic strategies. Controlling operating condition of roadside equipments at any time to synchronously receive and handle images and traffic information passed back from the foregoing equipments can forthwith present the latest road traffic conditions on Changeable Message Sign (CMS) or images on “Immediate Traffic Information Network for Provincial Roads” and APP mobile communication software, and provide people with information to keep away from traffic events and accidents for selection of the most appropriate routes and increase of traffic safety as well as travelling smoothly.
In consideration of increasing types and quantities of traffic control facilities set up by Directorate General of Highways, MOTC, and increase of fault frequency resulted from these gradually aging facilities, this study therefore explores several issues to ensure immediacy, correctness and stability for information quality collected by roadside traffic control facilities, i.e. traffic control facility software and hardware in the stage of maintenance, and appropriateness of Directorate General of Highways’ routing inspection operators, frequency and items for road maintenance and traffic control facilities maintenance. Furthermore, report and fault correcting operation process for routing inspection maintenance of the existing traffic control facilities, whether any improvement needed for application of facility maintenance management information system, etc. are necessary for deeper study. This study aiming at the current situation for traffic control facilities in the stage of maintenance and characteristics of use and maintenance by the way of statistic analysis for on-line rate of each traffic control facility and expert interview proposes active and effective management countermeasure to further improve management effectiveness for traffic information collection and control system maintenance.
