SPEED DETECTION OF MOVING VEHICLE USING SPEED

CAMERAS

Introduction What is speed camera?A speed camera is an automated ticketing machineIt includes a camera mounted invariably behind road signs or trees It can be extremely handy to monitor the vehicleA new method develop for both car extraction and speed detection

SPEED CAMERAS

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

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

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

DOPPLER EFFECT

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

fM = 2vfEcos(α/c)

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

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

TYPES OF SPEED CAMERAS

Gastrometer speed cameras

Peak traffic speed cameras

Speed spike cameras

Truvelo speed cameras

Specs system speed cameras

Gastrometer speed cameras

Manufacturer of the UK’s red light camera

Red light camera was originally used to measure red light offecences

PEAK TRAFFIC SPEED CAMERAS

Founded in 1990 and based in the Netherlands

It uses either loops within the road surface or radar

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

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

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

APPLICATIONS

Operation during the rain or mist

Measurement ranges

Reaction time

Continuous transmission

.

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

ADVANTAGES OF SPEED CAMERA

Speed costs livesEconomic benefitSpeed camera’s are a tax on the richGood for environmentHigh speed is bad for communities and other

type of exercise

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.

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.

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.
