crash report

Crash data, more so than any other regularly collected and readily reported public data sets, shine a bright light upon the most dangerous parts of our city's streets. Crash reports tell authorities who was injured, where, and under what circumstances, and the Illinois Department of Transportation collects the same information from all police departments statewide. IDOT uses these reports "for a number of vital purposes, including crash analysis, roadway engineering improvements, safety program design, and ultimately, preventing death/injury on Illinois roadways."
