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
