REAKT ISA is a joint project with HAW Kiel and the Northern Institute for Tourism in Kiel, funded by BMBFTR. In the ISA project, we jointly develop and test a highly automated, intelligent monitoring and communication system to support, secure, and inform passengers in autonomous local transport trains. The goal is the early detection of safety-critical situations and to provide trustworthy, user-oriented assistance during regular operation, for example, in cases of uncertainty or questions.
