The Horizon Europe research project IMPROVA has recently released its 4th Newsletter, focusing on enhancing road safety by addressing the complexities of long-term consequences (LTC) caused by road traffic crashes. This version of the Newsletter focuses on WP updates and advancements, as well as two IMPROVA papers presented during the IRTAD 2026 Conference in Athens. Key WP updates include the launch of the Functional Capacity Index and the integration of European crash data into a new head-injury metamodel.
