INTRODUCTION
Nowadays the number of people killed and injured on our roads remain unacceptably high.The main reason is speed of vehicle.
Speed Detection Using Speed cameras on the side of urban and rural roads, usually placed to catch transgressors of the stipulated speed limit for that road.
HISTORY
Speed cameras were introduced in west London in 1992 and following their success in reducing speed related crashes.
Speed cameras are recommended under use to reduce road casualties. The speed camera is also known as" safety cameras".
Speed camera uses the basic principle of Doppler Effect and RADAR technologies
The basic of every speed camera is a SHF generator, which can transmit the beams in specific directions.
The exact frequency is between 2 GHz and 15 GHz.
The power of oscillators is not very high (usually less than 10 mw), but the effect a power output is increased through the use of the directional aerials.
How Well Does it Works?
Operating during the rain or mist:
The RADAR works perfectly well during a rain or mist.
For ex:- RADAR is used extensively to help the landing of airplanes in bad weather.
mist doesn't move with respect to RADAR beams it will be practically invisible to the receiver and the measurements are completely unaffected.
Measurement Range:
The distance from which the RADAR can measure the speed of a vehicle depends on two factors:power of SHF oscillator andsensitivity of detector
Continuous transmission:
RADAR does not need to functioning continuously.
Actual RADAR equipment works on the random basis or is activated only when a vehicle comes near by.
When several vehicles traveling at different speeds encounter at the RADAR beams the resulting Doppler signal contains a mixture of signals at different frequency
Discimination
The majority of current devices can't separate these components and reject the measurement as faulty.
Types Of Speed Cameras :
Gastrometer speed cameras.
Peak traffic speed camera.
Speed spike camera truvelo speed camera.
Need for public Communications
We should make people aware of the speeding and benefits of speed cameras. We should make awareness in the local level, national level and also in government level.
Advantages:
Economic benfits.
Speed camera’s are tax on the rich.
Good for environment.
Reduce accidents & protects the innocent roads.
Conclusion
Speed is not the main couse of death.
Countries without speed cameras have lower death rates.
Aspeed camera designed to catch the speeding motorists.
Can also note number plates & insurense.
It can reduce 40% of accidents by the year of 2010.
