Table 1: _Cont._In the realm of operating and managing electromechanical facilities on highways, a robust industry standard system is yet to be established. Drawing on comparable industry standards and empirical engineering studies, this study has enhanced and broadened the functional classification, naming conventions, and facility details of electromechanical facilities to more accurately depict the attributes of intelligent expressway electromechanical configurations. The electromechanical facilities are categorized into five subsystems: monitoring system, charging system, communication system, power supply and lighting system, and information release system. Each subsystem may be subdivided into several subunits, each comprising multiple electromechanical devices.
