This precision map-based system collects, process, transmit, store, and maintain real-time dynamic information (sensor data, weather, roadside unit data). Essential technology for cooperative automated driving level 4 or higher, the system analyzes vehicle, pedestrian, and structure data for safe driving.
C-ITS and LDM Cooperative automated Driving System Comparison
LDM cooperative automated Driving system combines and processes road information and transmits it to vehicles as V2X messages without driver involvement.
LDM cooperative automated Driving system combines the dynamic information of C-ITS and the static information of HD map into LDM standard and generates accurate location information for transmission.
