Traffic Accident Analysis

The DuPage County Division of Transportation is responsible for collecting and analyzing traffic crash data on DuPage County highways.  Records are kept for over 5 years and many are also entered into a County database.

The County has also initiated a program called the Web-based Traffic Accident System that will allow the Sheriff and the various municipalities in the county to enter data directly into a central accident database and then to query that data and generate reports.  That database may be accessed by clicking on the following link:  www.dupageco.org/accidents.

For information about who to call to participate in the program and how to use the system, please refer to our Web-Based Traffic Accident System Guidance Document.
