Objective Five:
Improve the reporting and analysis of bicycle crashes.

Strategies

5.1 Determine how to improve the level and quality of reporting of bicycle crashes. Crash reports are not usually prepared unless a motor vehicle is involved. Unfortunately, this excludes 85 percent of bicycle crashes from the recorded statistics. Furthermore, many crash reports are incomplete. Determine the best strategies to encourage police officers to submit a complete Illinois Traffic Crash Report for all reported:

• Bicycle crashes on roadways or trails
• Bicycle-motor vehicle crashes
• Bicycle-bicycle crashes on roadways or trails
• Bicycle-pedestrian crashes on roadways or trails

Bicyclists should be encouraged to report all crashes. Crash data will make it easier to identify which violations to target for enforcement and educational efforts. Determine how to design the crash report form so that a bicyclist involved in a crash is treated as a vehicle operator, with identification of what the bicyclist’s position was before and after the crash. The form should ask for the location of the bicycle (on roadway, on sidewalk, on crosswalk); whether the bicyclist was riding with or against the traffic; if the crash occurred after dark; and if the bicycle had a working front light and rear light or reflector.
5.1.1 Performance Measure: Prepare report with recommendations how to improve the reporting of bicycle crashes by 2007.
5.1.2 Best Practices: Palo Alto, CA; Corvallis, OR
   
5.2 Identify locations with a high number of bicycle crashes; determine the primary factors contributing to these crashes; and implement appropriate engineering, education, and enforcement and countermeasures. Identify the probable causes of the crashes; injury types and trends; and other relevant issues, including sidewalk bicycling, wrong-way bicycling, nighttime bicycling without required equipment, failure to obey right of way rules, and crashes in driveways, parking lots, and trails. Consider examining ambulance, emergency room, hospital discharge, and mortality data in addition to police accident data.
5.2.1 Performance Measures: Identify locations every 2 years, beginning in 2007. Implement countermeasures at 5 – 10 problem areas per year, beginning in 2007. Submit an annual report with recommendations to prevent bicycle crashes to the Mayor’s Bicycle Advisory Council, beginning in 2007.
5.2.2 Best Practices: Los Angeles, CA, Department of Transportation, Bicycle Collisions in Los Angeles; New York, NY, TrafficStat system and the Manhattan Traffic Task Force Traffic Safety Team

Possible Funding

Federal traffic safety (Section 402) funds; National Highway Traffic Safety Administration; National Center for Injury Prevention and Control; Chicago Police Department; Chicago Department of Transportation; Chicago Park District; Chicagoland Bicycle Federation; grant funding from injury prevention foundations and organizations.
