Abstract
Accurate and reliable vehicle positioning is a crucial enabling technology for cooperative transportation systems especially for safety-related applications. However, technologies which comply with the necessary requirements are not yet available. Thus, a new architecture for this problem hasbeen developed in the European integrated project SAFESPOT. The main components of this development will be presented in this paper, including landmark-based positioning using cameras or laser scanners, infrastructure-based UWB-positioning, and communication based relative positioning. Furthermore, the integration of these technologies as well as evaluation results will be presented and discussed.
