III. DESIGN PROCESS:

On providing power supply to the arduino, the
system initially checks for alcohol using the alcohol
sensor MQ3 and on detecting the presence it doesn’t
allow the vehicle to start. Similarly we place a Light
sensor in the seat belt socket which detects the presence
or absence of seat belt and displays a message on LCD
screen. The LCD is interfaced with arduino. These are the
accident prevention modules.
Speed control module includes a speed controller

can also be extended by inducing automation concepts
like automatic driverless vehicle system, inter vehicular
communication etc.

IV. PREVIOUS SYSTEMS:

A New Algorithm for Pedestrian-Vehicular Collision
Avoidance Support System [1] (P-VCASS).It was based on
Inter –Vehicle Communications (IVC).But VCASS cannot
avoid collisions between vehicles and pedestrians, but
avoid just between vehicles.
Vehicular Ad-Hoc Networks (VANETs).They is
vehicle to vehicle and vehicle to road side infrastructure
networks [2].VANETs are subject to attacks due to their
vulnerabilities, one of the most compromising attacks is
called Sybil nodes attack.
Proposed collision avoidance system can prevent
traffic crashes. However it’s not feasible to change the
traffic signal setting in real-time.

V. CONCLUSION:
This study solves the issues like automatic speed
control mechanism, accident detection and information
sending.. From this we conclude that this system will
reduce the accidents and save the human lives. On the
whole this system proves to be very cost effective and
efficient The experimentations and results prove that the
