Nowon-gu Smart Crosswalk Service is LIDAR. The purpose of this study is to provide a real-time safety environment for school zone crosswalks by using sensors
to provide notification services by mixing digital twin and message to DIDs with good visibility. The technology introduced for this purpose is to count vehicles
approaching remotely and to count pedestrians in the school zone and deliver them to the LIDAR server, and to the LIDAR server. The server delivers the processed
information to the sign operation server and displays it in real time through the 3D screen and message screen using digital twin technology through the DID
installed on the crosswalk. If there is no vehicle approaching, a message delivered from the Nowon-gu operation server is displayed through DID.
