SPEED DETECTION OF MOVING VEHICLE BY USING SPEED CAMERAS

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 and 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 CAMERA.

DESCRIPTION :  A traffic enforcement camera (Speed Camera) is an automated ticketing machine.  It may include a camera which may be mounted beside or over a road.  Other technologies that law enforcement agencies can use to measure the speed of a moving vehicle uses Doppler radar to beam a radio wave at the vehicle, and then infer the vehicle's speed by measuring the Doppler effect- moderated change in the reflected wave's frequency.  Radar guns can be hand-held, vehicle mounted or mounted on a fixed object, such as a traffic signal.

Types

mobile speed cameras:  In Mobile Speed Cameras, cameras is installed in unbound cars that transmit radar beam across the road.  When the vehicle passes through it beam change in frequency,measuring the vehicle speed. And if the driver is travelling over the speed limit the photograph of the vehicle is taken automatically by camera.

FIXED SPEED CAMERAS:  Like mobile speed cameras these cameras are installed above the flow of traffic, transmits the radar beam which bounces of the vehicle.  This provide highly accurate measure of the vehicle speed.  Most red-light cameras, and many speed cameras, are fixed- site systems mounted in boxes or on poles beside the road. They are also often attached to gantries over the road, or to overpasses or bridges.

ADVANTAGES:  Cameras and number-plate recognition equipment can be used for purposes unrelated to enforcement of traffic rules.  Cameras installed can track the movement of vehicles for any purpose.

Issues Political issues:  There are a number of legal issues which arise as a result depending on local laws and the procedures used by the enforcing bodies. There are political issues associated with camera schemes which are often unpopular with motorists and in many areas motorists have lobbied against camera schemes.

Legal issues: Various legal issues arise from such cameras and the laws involved in how cameras can be placed and what evidence is necessary to prosecute a driver varies considerably in different legal systems. In some areas the cameras themselves have been ruled illegal. Other issues surround the actual type approval of cameras.

CONCLUSION  We finally have a solution to the speeding problem.  We would expect there to be a great number of these every were and that day would be highly visible and identifiable to make a drivers slow down.  We use traffic lights and other traffic manager to reduce the speed. One among them is speed cameras.
