The CARMONY project introduces an Interlinked Orchestration Framework for traffic management that integrates proven governance and business models, continuously refined using innovative simulation technologies with real-world traffic data. This approach aims to generate credible response plans, guidelines, and decision logics, fostering societal trust. Key stakeholders, including road operators, governments, and traffic managers, are involved from the project's inception, providing ongoing support. The framework is accessible via smartphone apps and online dashboards, aiding comprehensive traffic management decisions. It will be piloted in urban and highway areas in Spain and Luxembourg, focusing on enhancing traffic efficiency, safety, and sustainability, particularly in mixed traffic scenarios involving both manually driven and up to level 4 autonomous vehicles. Long-term simulations will demonstrate the system's impact, aiming to build trust among society and stakeholders. CARMONY anticipates significant improvements in traffic efficiency and sustainability, potentially reducing travel time and traffic jams by 10%, saving European society up to €10 billion and individuals 10-15 hours lifetime annually. In urban areas like Paris, it could reduce CO2 emissions by up to 280,000 tons annually. The CARMONY project aims to control traffic volumes via orchestrating individuals, based on optimizing traffic for everyone and focusing on individual requirements & needs, the orchestrator provides individual suggestions and leaves the final decision always to the human.
