william berry on 22 Oct 13"Since demolishing 78 traffic signals and installing 80 roundabouts, the northern Indiana city of Carmel has reduced the number of accidents by 40 percent and the number of accidents with injuries by 78 percent." There's a great lesson in here somewhere. I'm not sure of the exact structure for it, but here are some of my random thoughts. Let me know if you have others: Use Googlemaps and GoogleEarth in order to determine how many traffic lights are in a specific location in a county/city. Using the calculations in this article/video, how much could the county/city that you researched in Google maps have saved if they installed traffic circles rather than traffic lights. Extension - Research the number of accidents and injury/fatality stats for the area that you've researched. Using the calculations in this video/article, how many lives would traffic circles save in this area?
