This crash map depicts pedestrian-involved accidents on Philadelphia's roadways, including state routes, from 2007 through 2017. In that 11-year period there were over 18,000 reported incidents, including 373 fatalities. Those figures for 2017 were 1,542 and 37, respectively.
These figures are limited to reports made by city, county, and state officers, and thus reflect only a subset of incidents deemed severe enough to report.
