Abstract	In the US, the number of traffic fatalities has had a long term downward trend as a result of advances in the crash worthiness of vehicles. However, these improvements in crash worthiness do little to help protect non-motorists. Over the last few years, this has been reflected in the number of pedestrian fatalities increasing in both absolute and relative terms (up over 15% since 2009). In 2011 there were 4,432 pedestrians killed and an estimated 69,000 pedestrian injuries. This increased to 4,735 pedestrian fatalities in 2013 [1,2,3]. Recently, manufacturers have begun developing a second generation of crash avoidance systems that recognize and mitigate non-motorist collisions. This paper evaluates the performance of one implementation of this type of systems that is currently available for consumer purchase. System performance is assessed using a broad range of crash scenarios that were developed based on US crash data as found in GES and FARS for the harmonized years of 2010 and 2011. Test track simulations under these scenarios realistic settings based on the analysis of crash reports after eliminating pedestrian crash geometries that are not relevant for these "forward looking" systems. This generated a sample size 689 crash tests for one vehicle type where various measures of crash mitigation are constructed. Our analysis here focuses on the ability of these systems to prevent fatalities, serious injuries and prevent crashes altogether. We find that the evaluated system is about 30% effective in mitigating crashes, fatalities and social cost, those these mitigations occur for different types of crashes. For example, complete mitigation occurs for primarily low speed crashes which fatality prevention occurs for much higher speed crashes where impact occurs though at a lower speed. There are some crash geometries where no mitigation occurs, specifically those where the driver is in active control of the vehicle during turning maneuvers. Finally, we offer some suggestions about the appropriateness of future regulatory policy.
