The aim of this study was the evaluation of the new Euro NCAP (New Car Assessment Programme) pedestrian rating system on the basis of real world pedestrian accidents. Therefore a method for the evaluation of secondary safety ratings based on the influence on road safety has to be developed. Within the present study, a methodology for the benefit estimation of secondary safety systems based on the GIDAS (German In-Depth Accident Study) database was developed. The method was explained on the basis of a real-world accident. The results of the case-by-case analysis give an overview on the impact distribution of pedestrians in frontal accidents with passenger cars and show the proportion of vehicle impacts and ground impacts. Furthermore, the effects of optimised Euro NCAP test zones on the real-world accident scenario can be evaluated. The evaluation of 35 real test results show a correlation between the Euro NCAP point score and the expected real-world benefit. It can be seen that there is a rather good correlation between the number of achieved Euro NCAP points and the calculated benefit for the real-world pedestrian accident scenario Of course, the benefit within one Euro NCAP point level differs slightly between the tested vehicles which results from the distribution of green, yellow and red test zones across the vehicle front. Furthermore, it can be seen that an optimised lower leg test zone already leads to a considerable benefit (compared to the original GIDAS vehicle fleet and assuming that the vehicles in GIDAS achieve zero points, which is an underestimation!). Except for one vehicle (achieving nine points) all other vehicles have a benefit of at least 60 reduced MAIS2+ injured pedestrians which is the result of an optimised lower leg zone.
