INFRAMIX main target is to design, upgrade, adapt and test (in simulation and in real-world) both physical and digital elements of the road infrastructure, to enable the coexistence of automated and conventional vehicles, in specific scenarios, ensuring an uninterrupted, predictable, safe and efficient traffic; the key outcome will be a “hybrid” road infrastructure able to handle the transition period and become the basis for future automated transport systems. To achieve its objectives INFRAMIX selects a bottom-up approach. Instead of working in generic solutions with questionable impact, it builds on three specific high value (in terms of importance for traffic efficiency and safety) traffic scenarios, namely “dynamic lane assignment”, “roadworks zones” and “bottlenecks”. Although INFRAMIX is targeting mainly highways (expected to be the initial hosts of such mixed traffic) its key results can be easily transferred to urban roads.
