The Illinois Dept. of Transportation recently presented the Daily Herald with the list of the ten intersections in DuPage County where the most accidents took place. Topping the list was Route 83 and North Avenue in Elmhurst, with 79 accidents in 2005.
The list is not a ranking of the most dangerous intersections per se because the list does not take into account fatalities and serious injuries.
The common thread for all of the intersections listed there is that they are all intersections of major roads with traffic lights. All have relatively high speed limits which are ferquently ignored, as any regular driver on those roads can attest. The conclusion to draw: speed is the most important factor in producing accidents at these intersections.
