Novel Traffic Light Control Concept for Cooperative, Connected and Automated Mobility (CCAM) Testing

Abstract

Automated vehicle testing and proving processes impose special requirements for traffic light control. Connected and Automated Vehicle (CAV) functions and related traffic control mechanisms must be tested and validated in a fully flexible and controlled test environment requiring specific technical features compared to the classical traffic management systems. In the paper, a novel concept for traffic light control is introduced together with its technical realization aspects on both intersection and central management levels, i.e., a networked control system has been designed. The control scheme realizes a fully adaptable automotive industry application to support not only the CAV but the Cooperative, Connected and Automated Mobility (CCAM) testing in general. The real-time performance has been demonstrated and evaluated by various test use cases, where the network latency as well as the computation performance have been investigated via real-world-like scenarios. Finally, as a proof of concept, the developed traffic light control system has been tested successfully as a part of a digital twin framework at the ZalaZONE Automotive Proving Ground.
