Speed Detection of Moving Vehicles Using Doppler Effect

INTRODUCTION
Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering, education and enforcement and recognizes that there are many different factors that lead to traffic collisions and casualties. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduce the speed. One among them is speed cameras.
Speed cameras on the side of urban and rural roads, usually placed to catch transgressors of the stipulated speed limit for that road. The speed cameras are there solely to identify and prosecute those drivers that pass by the them who exceed the stipulated speed limit.
So speed limits are good idea. To enforce these speed limit, laws have been passed making speed an offence and signs have been erected so as to indicate the maximum permissible speed. The police can't be every where to enforce the speed limit and so enforcement cameras are there to do this work.
Nearly everyone slows down infront of the speed Camera. We finally have a solution to the speeding problem. Now if we are to assume that speed cameras are the only way to make driver's slowdown, and they work efficiently, then we would expect there to be a great number of these every were and that day would be highly visible and identifiable to make drivers slow down.
Speed cameras are invariably hidden behind trees, road signs and often the first indication that one is passing through a speed camera point are the ruler marks painted on the carriageway or flash of the camera when it goes off.
Speed cameras were introduced in west London in 1992 and following their success in reducing speed related crashes and injuries their use
