Research on Maintenance and Management System of Expressway Electromechanical Device under Circumstances of Road Network

Electromechanical system is involved with several fields like communication technology,computer technology,power supply technology as well as management science and so on,and is difficult to manage. Meanwhile,the system devices are laid along each section of road network,so the spacial lay-out brings about more difficulties for devices management. Therefore,it is necessary to study the characteristics of maintenance and management of expressway electromechanical device under circumstances of road network and to set up maintenance and management system of expressway electromechanical device based on Intranet and GIS by advanced information technology.
