> One very interesting approach I have seen overseas is a traffic light that turns red if you are speeding as you approach it. It's incredibly effective; instant feedback on your behavior, and immediate loss of any time you gained by speeding. No ticket, unless you run the light. Drivers quickly conclude they're better off by not speeding.
I think an even better application of this technology would be to catch people who aren't stopping at signs/lights, or not yielding at merges. Radar-equipped signs can handle the speeding case fairly well, but are useless in these other - and often more dangerous - cases.
A pretty common sight around here (western europe) which seems to work pretty well are dynamic reminder signs: electronic signposts with a speed radar, which simply displays your speed in green if you're under the limit, orange if you're a bit over and blinking red if you're way over (using fairly bright led arrays so it's visible in most conditions) Anecdotally, it seems to work pretty well, drivers do slow down whe…
I wonder how the HN commentariat would feel about this if it was a government agency behind this rather than a fellow hacker...
Saving the data for later mining, OCRing license plates to build a record of cars traveling around town, etc. would be a different story because that affects everyone whether or not they're choosing to break the law and spans more than a single incident in time.
Is it allowed in the USA for an individual to film public space?

This is gross, and reminds me of the nosy old ladies that 'patrol' the neighbourhood around here, only this guy knows C.
> At 4:27 p.m. last Wednesday, the system caught a Route 11 city bus doing 34 mph. Which isn't even fast enough to get a ticket from local police. In my state (which is not Virginia, and it will vary everywhere), local police are prohibited from using radar and need to use an actual stopwatch to track your speed. Obviously very error prone, and they're supposed to basically give you 10 mph leeway - meaning on that ro…
I live in Va, just not that part, and the rule of thumb is anything less then 10mph over and you generally won't get a ticket. The only exception to this is places like school zones.

That's ridiculous. A 35mph collision with a pedestrian would almost certainly result in a dead pedestrian. 25mph is usually survivable.[1] A 20mph speed limit, strictly enforced would drop pedestrian fatality rates to essentially 0.[2] 1: http://humantransport.org/sidewalks/SpeedKills.htm 2: http://www.visionzeroinitiative.com/
