In a control apparatus for a moving path, directional indicators comprise indication placed on moving handholding support permit discernment of the type of walk/stand traffic from a distance, passenger detecting devices monitor the absence/presence of a passenger within walking zones on an entry gate side and an departure gate side including floor boards of the entry gate side and the departure gate side, and the absence/presence of a passenger within walking zones on the entry gate side and the departure gate side adjacent to and beyond the walking zones. When a passenger is detected in the walking zone on the entry gate side in a conveying mode, a mode switching circuit switches the operating mode to an entrance alert mode, and when a passenger is detected in the walking zone on the departure gate side in the conveying mode, the mode switching circuit switches the operating mode to an exit alert mode.

A monitoring system for an escalator including: a local gateway device; an analytic engine in communication with the local gateway device through a cloud computing network; a sensing apparatus in wireless communication with the local gateway device through a short-range wireless protocol, the sensing apparatus including: an inertial measurement unit sensor configured to detect acceleration data of the escalator, wherein at least one of the sensing apparatus and the local gateway device is configured to determine a condition based monitoring (CBM) health score of the escalator in response to at least the acceleration data, and wherein the local gateway is configured wirelessly transmit the CBM health score of the escalator to the cloud computing network in a data package via a long-range wireless communication protocols.
