Prototypes of the latest version of a biofidelic flexible pedestrian legform impactor (Flex-GTR-proto) were developed in November 2008. In this research several technical evaluations on the Flex-GTR-proto were conducted. As a result, fairly good repeatability and reproducibility of the Flex-GTR-proto, and comparability of the Flex-GTR-proto output under the symmetricright and left bumper corner impacts were observed (majorities of CV values are less than 3%). As for the comparability between the Flex-GT and Flex-GTR proto, some differences were observed between them. Most of the maximum value ratios of Flex-GTR-proto relative to the Flex-GT are less than 1.1. The difference between the Flex-GT and Flex-GTR-proto has a chance to affect the injury threshold values; therefore, a following research has been investigating the threshold values for the Flex-GTR-proto using the ratios of the Flex-GT and Flex-GTR outputs and/or using the correlations between the Flex-GTR-proto and human lower extremities outputs which can be obtained from a computer simulation analysis.
