Abstract：This study aimed to investigate the lower extremity injury risk using the real world accident data. For this purpose, a subsample of 354 cases with pedestrian lower extremity injuries from German In-Depth Accident Study(GIDAS) database, were used to conductvariance testanalysis to check whetherimpact speed, pedestrian age, height and weight are statistically significance for pedestrian with or without serious lower extremity injuries. Then, serious lower extremity injury risk model was developed. The results revealed that impact speed and age are statistically significantpredictors for pedestrians sustaining serious lower extremity injuries. Risk of injuryincreases with increasing of impactspeed as well as does age was also found according to the data analysis. In the selected sample, the serious lower extremity injury risk is 50% probability at impact speed of 43km/h.
