CONTENTS

A speed cameras is an automated ticketing machine

It includes a camera mounted invariably behind road signs or trees

It can be extremely handy to monitor the vehicle

A new method develop for speed detection

INTRODUCTION what does it mean by speed camera?

PLACES OF USE

WHY SPEED CAMERAControl Vehicle SpeedTraffic ControlCrime ControlAccident Control

The Dutch Company Gatsometer B V, which was found in 1958 produced the Gatsometer

The first Radar for use with road traffic in 1971

The first mobile speed traffic camera in 1982

Speed camera was introduced in West London in 1992

Following their success in reducing speed was expanded to many other areas in Great British

HISTORY

RADAR makes use of electromagnetic waves to detect objects

It gives information about speed distance of objects

It makes use of Doppler effect to determine vehicle speed

BASIC PRINCIPLE INVOLVED IN SPEED CAMERAS

The apparent change in pitch due to relative motion between source and observer

Doppler first proposed this effect in 1842

The principle of this effect is well known in the study of sound known as Doppler effect

INTRODUCTION TO DOPPLER EFFECT

The principle of speed camera that is Doppler effect can be described by the formula

fM = 2vfEcos(α/c)

This effect measure and scale frequency variation between the radio wave sent and radio wave received.

DOPPLER EFFECT

DOPPLER EFFECT

It doesn’t make use of Doppler effect

This system calculates the distance at which the object is and from the change in distance monitored in a specific time lapse

The frequencies used by Lidar are higher and more difficult to jam

TYPES OF SPEED CAMERAS

GASTROMETER SPEED CAMERAS

Manufactured of the UK’s red light cameras

Red light cameras originally used to measure red light offecences

PEAK TRAFFIC SPEED CAMERAS

Founded in 1990, and based in Netherlands

It uses either loops within the road surfaces or radars

SPEED SPIKEThese new type of

cameras communicate with each other via the GPS satellite

NetworkIt can track a vehicle

using number plate recognition

Allow two cameras talk to each other

TRUVELO SPEED CAMERAS This system is designed

to take photographs of the front of a passing vehicle

This allows the picture taken to show the driver of the vehicle as well

It uses infrared flash which produces no visible flash to the approaching driver

SPECS SYSTEM SPEED CAMERAS SPECS cameras

were introduced in 1999

• It consist of 2 video cameras each fitted with infrared illuminators

• It gives ability to work 24/7

Operation during the rain or mistMeasurement ranges Reaction timeContinuous transmission

APLLICATIONS

A new approach of vehicle extraction and speed detection was proposed

These cameras reduces accidents and protect innocent road users

The system also provides location and information ,velocity of the each vehicle

It can reduce 40% rate of accidents by the year of 2015

CONCLUSION

Any queries ?????

Thank you
