The Surface Transportation Policy Project has been reporting on pedestrian fatalities in the United States for ten years now. Our first report, produced with Environmental Working Group and published in 1996, examined pedestrian fatalities for the period 1986 through 1995. Since that first Mean Streets was published, STPP has issued three updates, each looking at a two-year period. This year, STPP is taking the opportunity with the publication of our fifth edition of Mean Streets to reflect on the trends in pedestrian safety over the past decade.
