Pedestrian-vehicle traffic accidents are a globally recognized safety concern. UN/ECE/WP29 established the Global Technical Regulation (GTR) for pedestrian safety on 12 November 2008. GTR is expected to significantly reduce the injuries of pedestrians in the event of frontal impacts. Recently, a new pedestrian lower legform named Flex-PLi has been developed for the body model of the human lower leg. Flex-PLi is introduced, and the characteristics of the model are identified through a comparison study with an existing lower legform. Usability, durability and repeatability are evaluated by using real vehicle impact tests. Moreover, the model is examined by considering the possibility of its application to pedestrian safety GTR phase 2.
