Police Using GIS for Vehicle Accident Reporting

When a major traffic accident occurs within DuPage County, an
accident task force called MCRT (Major Accident Reconstruction Team)
comprised of officers from many different departments throughout the
area is sent to the scene of the accident to do an investigation and
write an accident report. The final report consists of different
criteria including a written portion which describes the events that
took place during the accident. And a visual portion which is a drawing
at a scale of 1 to 10 feet that displays things such as: distance
traveled, impact zones, and the final resting spot, among other things.

Given the odd nature of this accident, which involved a vehicle
traveling off the road at high rate of speed, and going thru a creek and
into a tree. A detective from the Oak Brook Police Department
requested the assistance of GIS in displaying the vehicles final resting
position. His goal was to take the image drawn by the MCRT team and
lay it over high resolution aerial imagery in an effort to display the
actual location of the final resting spot. Using GIS was a perfect
solution for the final product they were seeking because of GIS’ ability
to georeference images to a chosen scale. By taking known geographic
points within their initial accident sketch, the GIS specialist was able
to match the sketch to real locations found in the imagery. The image
shown displays the final resting position of the vehicle, drawn by MCRT
staff, laid over aerial imagery while maintaining the scale of 1 inch
equals 10 feet. This new image can now be used in court while
describing the events that took place during the accident.
