In DC, the absolute speed limit is 55 miles per hour on interstate highways and 25 miles per hour on all other roads unless otherwise designated. In alleys, it is 15 miles per hour. On roads in school zones, the speed limit is 15 miles per hour when the school zone sign is flashing. Here you can find all relevant information about Road Speed Limiter. Radar equipment detects vehicles that are exceeding a threshold speed above the speed limit, then triggers a camera which is linked to the radar equipment.. The law authorizing automated traffic enforcement in the District of Columbia can be found in the DC Official Code (Division VIII, Title 50, Subtitle VII, Chapter 22,. Another distinctive feature of limiters is that they do not stop the motor and let the controller enter Alarm state; they merely limit voltage, current and motor revolution speed. For DC motors: Max voltage is the nominal motor voltage. It defines maximum motor winding woltage. It is usually used to limit voltage growth when the. A proposal by the D.C. Department of Transportation would lower the default 25 mph speed limit to 20 mph on some neighborhood streets and create 15 mph zones 7 a.m. to 11 p.m. on roadways around schools, parks, senior and youth centers. It even allows you total control of the speed of individual users downloading from you. www.netlimiter.com [edit] p.s if you are on a 512/128 connection such as myself, you can limit your upload to 11kB/s without affecting your down speed. A higher upload limit would hamper your down speed. DC's appetite for camera tickets isn't on the mind of many visitors--especially if they don't have the cameras back home. Or they don't know the local speed limit, blinked when going by a 25 mph sign and are used to driving in a city with a 30 mph limit (say, NYC). A perfect storm for a camera ticket IMHO.

I think your basic idea is OK, but the pot idea is not very good. The problem is that you have to take the position signal and differentiate it to get speed, and noise will be a big problem. What you need is a rotary rate sensor, and there are a variety of these. An obvious choice would be a tachometer. DC. 1200 New Jersey Ave., SE. Washington, DC 20590. Abstract.
