Reliable Information Aggregation and Exchange for Autonomous Vehicles

The Stadtpilot project develops a vehicular technology targeting autonomous driving in metropolitan areas. Currently, demonstrations focus on the German city of Braunschweig. These activities are further supported by the AIM test bed, which provides communication infrastructure along Braunschweig's inner ring road. Besides communication capabilities, an autonomous vehicle needs to have a complete, consistent and correct understanding about its surroundings to enable safe driving. For this purpose, this paper presents a novel approach for information aggregation and exchange through a context model tailored for urban environments. Furthermore, integration of C2X hardware into the existing traffic infrastructure is shown.
