The main objective of INFRAMIX is to prepare the road infrastructure with specific affordable adaptations and
to support it with new models and tools, to accommodate for the step-wise introduction of automated vehicles.

Design and develop elements for the new digital road infrastructure, integrating also information received by automated vehicles; in turn, this digital infrastructure will become the basis for an enhanced electronic horizon for automated vehicles.

Adapt and upgrade elements of the existing physical infrastructure to enable the stepwise insertion of automated vehicles.

Develop new traffic flow models (sub-micro and microscopic) combined with mature simulation tools (e.g. VSimRTI, ICOS) integrating real vehicle algorithms for automated driving and human driver behaviour to examine mixed traffic scenarios under various penetration rates of different levels of automated vehicles.

Design and implement traffic estimation, monitoring and control strategies dynamically adapted to the different penetration levels of automated vehicles, the infrastructure equipment and the overall traffic status.

Develop a hybrid testing system by coupling infrastructure elements and vehicles on real roads (or test tracks) with virtual traffic environment including representative mixed traffic situations within the three predefined scenarios.

Design new forms of visual and electronic signals to be integrated into the “hybrid” infrastructure, making them readable and “understandable” by both automated and conventional vehicles.

Evaluate users’ appreciation and acceptance in terms of visual signals, messages and relevant TMC control actions developed for mixed traffic scenarios.

Evaluate safety performance in the three selected scenarios, for mixed traffic situations; collect /monitor critical situations mixed traffic data to identify new safety performance criteria for road infrastructure.

Design and create consensus for a scheme of classifying road infrastructure into “automation- appropriate” levels.
