We are developing a system for influencing traffic signalling systems to enable emergency vehicles to pass through road traffic more quickly. The system is integrated into traffic lights and changes their switching in favour of emergency vehicles in the event of an emergency. This makes them faster than with light and sound signalling devices, such as sirens. The system is undergoing long-term testing with great success in co-operation with the Technical University of Karlsruhe in Winnenden and the Technical University of Berlin in West Berlin.
