Currently I work for Purdue, doing a post-doc here. I do research in the area of traffic signals,traffic flow, and lots of vehicle detection. We have done a ton of research in the last year regarding video detection, the use of cameras as opposed to loops in the pavement. The majority of cameras are either PTZs for surveillance (Traffic Ops Center) or detection units.

The linkis a picture of me and my boss (I am not wearing the tie) at one of our data collection test sites. There are lots of camera in the background.

Do you happen to know ifintersections with these cameras show an increase in rear-end collisions?
Ata particular intersection, froma pure vehicle-damage cost stand point,does the total cost of collisions(including the total cost of monitoring) go up or down with the addition of red light cameras?
The same question for injuries.
Thanks!

RE: red light camera
Some new stoplights use what looks like a camera to detect if a car is waiting at the read light. It may not have been a camered (sp?) intersection just a different type of traffic detection.... Most of these items are shapped kind of like the white camera but smaller and typically black....

This is off topic, but what the heck.

I did a quick search
http://ntlsearch.bts.gov/tris/search...;o=1&new=n
and this one relevant document shows that accident rates decrease. However, the abstract doesnt specify what type of collisions they were. I would guess it involves the entire intersection.
In all honesty, if you are following so close to the car in front of you that you cant stop in the event that they stop, well, there isnt much any traffic engineering can do to help you.
