These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger
This can be done by monitoring the distance betweeen nearby cars and alerting the driver whenever the distance becomes too short
INTRODUCTION
Since bluetooth devices are capable of communicating with eight other devices simultaneously we can monitor and check the speeds of up to eight cars simultaneously ,thus preventing accidents

ACCIDENTS IN THE WORLD
OPERATION
Because of travelling at high speed there is a possibility of accident.
Bluetooth is a radio is a short distance ,low power radio operating in the unlicensed spectrum of 2.4Ghz and using a nominal antenna power of 20dbm.

BLUETOOTH PC CARDEvery car should have mini computer to monitor the relative position of the car
BRAKE SYSTEM COMPONENTS
AUTOMATIC BRAKE SYSTEM
*Four main components to an automatic braking system: 1)Speed sensors. 2)Pump. 3)Valves. 4)Controller.*On receiving the control signal from the travelling car the computer inside the car manipulates the signal and gives control signal to the braking system.
*In position one, the valve is open , pressure from the master cylinder is passed right through to brake.
*In position two, valve blocks the lines isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder.
*In position three, the valve releases some of the pressure from the brake.
VARIOUS FUNCTIONS OF HYDRAULIC VALVES
Within 10m
Sends warning signal Receives signal and control the speed of car
PRESENTATION OF IDEA
* when car a and b come close with in the range of 100m then both the Bluetooth devices get enabled.* If any one of the car comes too fast then Bluetooth device gives signal to another car and it process the signal and gives it to the automatic braking system .
CONCLUSION
Bluetooth communication device will thus be a small, low powered radio in a chip that will talk to other Bluetooth enabled products.
Thus, this technology helps make the electronic devices more friendly and helps address various other problems like accidents
