CMC work is supported now by seven world leading motorcycle manufacturers. The Italian make Ducati has joined the consortium recently, following KTM from Austria, next to Japanese makers Kawasaki and Suzuki. BMW Motorrad, Honda and Yamaha remain the core members and have been the driving force to establish CMC. CMC can now also welcome a major player in automotive connectivity. Autotalks is known for its top end developments in vehicle communication systems and will actively support CMC as Development Member. Under its WG Unification & Interoperability, CMC has established a special task group dedicated to evaluation of HMI criteria in the context of C-ITS messages. Together with CMC member WIVW (Würzburg Institute for Traffic Science) 2 riding simulators are used to investigate the optimal information strategy and evaluate warning timing for various C-ITS functions.
