Since my original post, I've done some research. It turns out someone is already making a map of all of the red light intersections in Chicago (and other cities). However, their list has duplicates. But if you live in a city other than Chicago, this is a great list to start out with.
Thanks to MJ, I found that the City of Chicago website lists all of the intersections with Red Light Cameras.
I got the list and mapped all 59 locations of Chicago's Red Light Cameras. Let me know what you think.
I was happy to see that I only pass one red light intersection on my way to the train station every morning.
