Autonomous vehicles will only bring the hoped-for increase in convenience and safety if they reliably know their own position – and can reliably recognize their static and dynamic environment, i.e. other vehicles and road users, as well as buildings and infrastructure. The vehicle sensors themselves and the algorithms which enable reliable real-time evaluation of the recorded data all play an important role here. However, these sensors and algorithms can also be used to analyze and optimize the flow of traffic. No less important: infrastructure components such as car parks can collect data on utilization and availability and make it available to vehicles (both autonomous and those driven by people).
