I2V Message Architecture of DSSS (Driving Safety Support Systems) and LDM (Local Dynamic Map)

For Infrastructure to Vehicle (I2V) communication based cooperative systems, it is indispensable to grasp accurate travel distance between intended vehicles and target objects notified from RSU (Road Side Units) so that OBU (On-Board Units) can judge the presence and severity of dangers against the target objects. Thus, Local Dynamic Map (LDM), which is the technology to put the position of intended vehicles and target objects on a map and to express the relative distances, attracts attention. On the other hand, Driving Safety Support Systems (DSSS), which has been studied by the Universal Traffic Management Society (UTMS), realizes the function corresponding to LDM by defining dedicated map data as road topology information around target intersections where services are provided, and offering it to OBE through I2V communications. In this paper, the authors introduce the architecture of I2V message sets of DSSS as well as the structure of road topology information as a practical use case with LDM.
