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 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, the solely to identify and prosecute those drivers that pass by them when exceed the stipulated speed limit. At first glance this seemed to be reasonable that the road users do not exceed the speed limit must be a good thing because it increases road safety, reduces accidents and protect other road users and pedestrians. So speed limits are good idea. To enforce these speed limit; laws are passed making speed an offence and signs are erected were of to indicate the maximum permissible speeds. The police can't be everywhere to enforce the speed limit and so enforcement cameras art director to do this work; on one who's got an ounce of Commons sense, the deliberately drive through speed camera in order fined and penalized. So nearly everyone slowdown for 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 everywhere and that day would be highly visible and identifiable to make a 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 is the ruler marks painted on the carriageway or flash of the camera that it goes off. you can download this ppt from here https://adf.ly/NKGqe

1. “speed detection of moving vehicle using
speed cameras”

2. Introduction
What is speed camera?
A speed camera 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 both car extraction and
speed detection

3. SPEED CAMERAS

4. HISTORY
• The Dutch Company Gatsometer BV,which was
founded 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 Britian

5. BASIC PRINCIPLE INVOLVED IN SPEED
CAMERAS
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

6. INTRODUCTION TO DOPPLER
EFFECT
The apparent change in pitch due to relative
motion between source and observer
The apparent pitch produced by sounding
body appears to be higher than actual pitch
The principle of this effect is is well known in
the study of sound known as Doppler effect

7. DOPPLER EFFECT
The principle of speed
camera that is Doppler
effect can be described by
the formula
 fM = 2vfEcos(α/c)

8. FROM THEORY TO PRACTICE
The basic of every speed
camera is SHF generator
It can transmit the beam in
specific directions
Power of oscillator is
usually less than 10mw
It checks whether the
measured speed exceeds
the present value

9. VEHICLE SPEED DETECTION BY
LIDAR
It does not makes 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 here are higher and trickier to
jam

10. TYPES OF SPEED CAMERAS
Gastrometer speed cameras
Peak traffic speed cameras
Speed spike cameras
Truvelo speed cameras
Specs system speed cameras

11. Gastrometer speed
cameras
Manufacturer of the UK’s red
light camera
Red light camera was originally
used to measure red light
offecences

12. PEAK TRAFFIC SPEED CAMERAS
Founded in 1990 and based in
the Netherlands
It uses either loops within the
road surface or radar

13. SPEED SPIKE
these new type of cameras
communicate with each other via
the GPS Satellite Network
It can track a vehicle using
number plate recognition
allow two cameras to 'talk' to
each other

14. 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 an infra red flash which
produces no visible 'flash' to the
approaching driver

15. SPECS SYSTEM SPEED CAMERAS
Speed Violation Detection
Deterrent, SVDD is the digital brain
which the SPECS system is based
upon
It consist of two video cameras each
fitted with infra red illuminators.
It gives the ability to work 24hrs
7days a week

16. APPLICATIONS
Operation during the rain or mist
Measurement ranges
Reaction time
Continuous transmission
.

17. COMMUNICATIONS AND PUBLIC
AWARENESS
A key objective was to ensure that people are made
fully aware of the speed cameras
make people aware of the speeding and benefits of
speed cameras
 make awareness in the local level, national level
and also in government level about these speeding
and casualties due to speeding

18. ADVANTAGES OF SPEED CAMERA
Speed costs lives
Economic benefit
Speed camera’s are a tax on the rich
Good for environment
High speed is bad for communities and other
type of exercise

19. CRITICISMS OF SPEED CAMERAS
They cause accidents because people brake
from 40 to 30mph.
Speed is not the main cause of death.
Countries without speed cameras have lower
death rates.

20. FUTURE TECHNOLOGIES
A speed camera designed to catch speeding
motorists
 The asset camera should be able to pick out
drivers who are not wearing
 identify tailgating
 can also note number plates and recognise
cars with out-of-date tax discs and no
insurance.

21. CONCLUSION
 A new approach for vehicle extraction and speed
detection was proposed
 These cameras reduces accidents and protects the
innocent road users
 The system also provides location and velocity
information for each vehicle as long as it is visible-
 It can reduce 40 percent it of accidents by the year of
2010.
