Being able to check traffic density before you head out is really useful. Every first world country should have it.


Cameras do a pretty poor job of monitoring overall traffic. They can help focus in on what might be causing it (unreported accident, mass of animals in the highway, whatever)

The cameras on the major highway in Colorado Springs were pretty worthless, since you had to look at tons of images, and still not have a good picture of your entire commute.


To me it doesn't matter what it causing it, if it's gridlocked then I know to avoid it and use another route. I rarely need to see the whole route, just the hotspots.

From what I understand, the use of CCTV was started by the Brittish government in the 70s, due to the IRA attacks of the time. And while the system didn't stop the 7/7/05 bombings, it did help to find those that attempted the 21/7/05 bombings. I do have to question why so much surveillance is needed though. One of the many differences between US and UK culture I suppose.


Of the cities I know, CCTV of that complexity has only really been round in the last 10 or so years. I feel safer walking through the city center late at night as a result.

Why anyone would have a problem with it is beyond me.... unless they've got something to hide. I highly doubt Big Brother gives a toss that I went to WH Smiths this afternoon.
