Poster: Road Sensor Messages for V2X Scenarios

Roadside infrastructure, equipped with traffic and environmental sensing technologies and leveraged by vehicle-to-everything (V2X) communications, plays a key role in Cooperative Intelligent Transportation Systems (C-ITS). By providing additional road state information to Cooperative, Connected and Automated Vehicles (CCAVs), as well as to drivers of connected vehicles and to road operators, better decision-making outcomes can be obtained, thus improving overall traffic safety and efficiency. This work proposes a modular and scalable road-side C-ITS architecture, by including road sensors for weather, environmental, infrastructure, and traffic data collection, which communicate with roadside units (RSUs) for data processing and alert dissemination. A new message type is introduced, the Road Sensor Messages (RSMs), to aggregate data coming from sensors localized in the vicinity of the RSUs and transmit such information to remote Traffic Management Systems (TMSs) and, eventually, to the local V2X environment via short-range wireless communications.
