Pedestrian Safety in Illinois, 1990-2000

Cook County’s fatality rate per population was only exceeded by three other counties Williamson, Kankakee and Effingham. In suburban Chicago, McHenry and DuPage had fatality rates less than one-third of the rate in Cook County. On a national scale, DuPage has the second lowest rate among counties with over half a million people. When the degree of walking is considered Cook County falls within the middle of the Chicago-area counties. The lowest rates are in DuPage and Will Counties and the highest are in Kane and Will Counties.

Pedestrian fatality data were obtained for each of the 102 counties in Illinois for an eleven-year period (1990-2000 inclusive). Fifteen of the counties did not have pedestrian fatalities; Kendall County (population of 47,000) was the largest. The study period showed an annual statewide decline from about 275 fatalities to less than 200. Each year Cook County accounted for more than half of the fatalities but it dropped from 160 in 1990 to 101 in 1999 before a slight uptick in 2000. The statewide changes tend to mirror the changes in Cook County. The objective of this study was to identify the factors that are related to pedestrian fatalities in Illinois in the 1990s. Download the "Pedestrian Safety in Illinois, 1990-2000" study.
