The growing interest in light categories of vehicles, such as e-bikes, e-scooters and L7e vehicles, combined with a notable increase in road accidents in Europe for these categories, has underscored the urgent need to improve their safety. Currently, the legislative framework is outdated to ensure proper safety, especially if compared with conventional passenger cars. The definition of analytical tools that can accurately predict injury outcomes to analyze real accidents scenarios is essential to understand, in the design phase, whether a vehicle can be considered as safe and reliable by road users/consumers. The proposed work focuses on the development and application of numerical methodologies, specifically finite element methods (FEM) and multibody (MB) analysis, to evaluate injury criteria in road accidents involving micro-mobility vehicles, with emphasis on two wheelers .
