Introduction

The major cause of motor accidents is over speeding.to avoid this goverment has In various locations in the city the speed of vehicle is limited to certain speed. But usually the drivers of vehicle tend to ignore the speed limit. The statics shown below gives us a clear picture about the mortal rate due to overspeeding of vehicles.in places like school ,hospitals and overcrowded public places speed limit is neccasry.

Working

Vehicle enters a certain

speed zone

Speed limit is sent by RF transmitter

RF reciver recives the speed limit

Driver is warned

about the speed zone

The vehicle check

whether in speed limit

The speed limiter

brings down the vehicle speed to desired speed.

APPLICATION Traffic application IN residential societies Near schools Railways crossing Highway junctions

ADVANTAGE

• The traffic police is not well equipped to handle and prevent these kind of accidents.

• VSL does the task for them without any human intervention

• VSL could bring down the accidents drastically.• VSL could help stop crime

•

Limitationo Costo Large scale implementationo Securityo Effectiveness

Conclusion

We have tried to come up with a concept that can actually be implemented in our day to day life and help to your society. We have been successfully developed a system which will save life's and make the roads saver in the near future.
