INTRODUCTION

“DOCTORS COME AFTER ACCIDENTBUT WE ENGINEERS CAN PREVENT

ACCIDENT”

CAUSES

• Unsafe act of people• Unsafe physical or

mechanical conditions

• Act of nature

3 E’s

• Engineering • Education and

training• Enforcement of

policies and procedure

ROAD ACCIDENT STATISTICS

BLUETOOTH• Connectivity • Tool used to communicate with other devices

within a specified range• BLUETOOTH RADIO – Short distance, low

power radio operating in the UNLICENCED SPECTRUM of 2.4 GHz

• Capable of connecting 8 devices at a time• The group of 8 devices is called as PICONETS

WHY BLUETOOTH?

• OVER RADAR:

Time - Radar can take up to 2 seconds to lock on

Radar has wide beam spread (50 ft diameter over 200 ft. range)

Cannot track if deceleration is greater than one mph/second

More interference sources

BLUETOOTH

• The road accidents can be avoided if there is a mechanism to alert the drivers

• This can be done by monitoring the distance between near by cars

• Alert the driver whenever the distance becomes too short

• Bluetooth technology serves this process

OPERATION

• To communicate with bluetooth standard the equipment must be within 100 m (at 10 db)

• Any car comes close bluetooth device sends warning signal to the car

• Based on the control signal

Reduces the speedOvertake the nearby car

AUTOMATIC BRAKE SYSTEM

• The manipulated signal is given to the braking system

• Four components of automatic braking system:

Speed sensor

Pump

Valves

Controller

MODES OF OPERATION

• Position 1 : Open• Position 2 :

Block• Position 3 :

Release

ONE TOUCH OVERTAKING SYSTEM

• Red car want to overtake the blue car

• Sends control signal via bluetooth to the blue car

• After the acknowledgement from the blue car red car can overtake without any collision

VIDEO BASED MONITORING

• Digital video camera is mounted in front part of the car

• The captured video is transmitted via bluetooth to the trailing car

• Driver of the trailing car will take wise action

EYE BLINK DETECTOR

• A new technology to prevent accident• Mostly effective in night driving• Driver’s drowsiness is recognized as an

important factor

EYE BLINK DETECTOR• Involves measure of eye blink using IR

sensor• IR transmitter – transmits the IR rays in our

eye

• IR receiver – receives the reflected IR from our eye

• Output is given to alarm circuit

BLOCK DIAGRAM

FUTURE SCOPE OF EYE BLINK DETECTOR

• Eye blink detector in combination with bluetooth technology can alert nearby cars

• Alert can be given to the driver via fake call• Instead of alarm, automatic braking system

can be used to reduce the speed of the car• Incase of transport vehicles, alert can be

directly sent to their owners

ALCOHOL DETECTOR

• Major reason for road accidents is DRUNK AND DRIVE

• For the safety of the people seating inside

OPERATION

• Install the sensor inside the car• Produces an signal if the driver is detected as

drunk• This signal output is sent to the

microcontroller through the comparator IC• Buzzer is turned on• Ignition is deactivated

FUTURE DEVELOPMENT

• We can implement GSM technology to inform the relatives or owners of the vehicle about the alcohol consumption

• We can implement GPS technology to find out the location of the vehicle

• In worst case, near by cars can alerted

CONCLUSION

“Preventable accidents, if not prevented due to our negligence, is nothing short of murder”

• Even though many technologies are there the alertness is up to the individual

• Accidents can only be prevented by not violating the rules

• Use these technologies to get benefited

• Thus we conclude that we engineers must contribute ourselves to invent new technologies in order to prevent accidents.
