Crashes Down At Western Springs RLC Intersections?
Village officials in west suburban Western Springs say crashes are down at two intersections where red light cameras were installed back in 2009 according to The Doings newspaper.
Crashes dropped at the intersection of Ogden and Wolf Road from an average of 23 in the three years before 2009, to 11 per year since May 2009.
At the village’s other RLC located at 55th and Wolf Road, crashes dropped from seven before the cameras to four in 2009 and just one in 2010, after cameras were installed.
The Illinois Department of Transportation has not released 2011 crash data.
One thing the story and village officials ignored in their analysis is that IDOT changed the way crashes are documented back in 2009–the year the cameras were installed in Western Springs.
As of January 1, 2009 accidents that resulted in less than $1,500 in damages were not reported as crashes. Before the threshold change, any crashes resulting in $500 or more were reported.
So while the superficial data from Western Springs is indeed promising as crashes seem to be declining, it is possible some, most or all of the declines could be attributed to this reporting change.
