AIMES ecosystem provides a real-world platform for collaborative trials based on the streets of Melbourne to test integrated transport technology to deliver safer, cleaner and more sustainable urban transport outcomes. Lexus Australia conducted Cooperative Intelligent Transport Systems (C-ITS) research within the AIMES ecosystem, including the development and demonstration of vehicle-to-infrastructure (V2I), vehicle-to-network (V2N) and vehicle-to-vehicle (V2V) safety applications (also called use cases). V2I safety applications involve direct communication between C-ITS vehicles and roadside units that broadcast live signal status and road geometry information of the intersections to alert drivers to the risk of violating red-light signal and running into pedestrians/cyclists crossing during the permitted phase. V2N safety applications include long-range communications with a cloud-based central facility to alert drivers to road hazards, traffic jams, and roadworks and provide drivers with information about static or variable speed limits. The extension of V2V on communication with emergency service vehicles and public transport vehicles allows sharing of awareness messages between different vehicle types. Notifying drivers of the stationary and approaching emergency service vehicles can assist in avoiding collisions and shorten travel time for ambulances. Tram awareness alerts and tram passenger warnings can potentially mitigate vehicle collisions with trams and passengers, enhancing public transportation's efficiency and safety. This paper discusses the importance, design and evaluation of C-ITS use cases in AIMES and highlights key findings and next steps for C-ITS deployment in Australia.
