ACCIDENT DETECTION AND NOTIFICATION SYSTEM

1. PRESENTED BY SOLOMON MUTWIRI
WILLIAM ATEKA
SUPERVISOR: Mr. HENRY KIRAGU

2. INTRODUCTION
 The aim of this project is to
detect accident and report the
accident spot to emergency
responders
 traffic accidents are one of the
leading causes of fatalities in the
Kenya.
 An important indicator of
survival rates after an accident is
the time between the accident
and when emergency medical
personnel are dispatched to the
scene.

3. OBJECTIVES
General Objective
 To design system that minimize the accidents’ response time
when an accident occurs and the time emergency responders
reach the accident scene in reducing human deaths due to
road accidents.
 Specific Objective
 To design a system that detect and locate location
accident spot ;helping vehicle occupants even when they
are incapacitated and subconscious.
 Increase safety of road users and comfort of passengers.

4. JUSTIFICATION

5. PROJECT LIMITATION
 SCOPE /LIMITATATION OF
THE PROJECT
 The following limitations
were note during our
research;
 Difficult for communication
in areas with poor coverage of
GSM network and GPS
communication
 Change of car ownership
would result in need to
reprogram the system details.
 Traffic jams can slow down
the emergency responders.

6. EARLY WORKS
911 Emergency system
 When an accident occurs only GSM information is
sent to emergency responders
 Not possible to locate the spot
ECALL
Its expensive
Not accepted widely

7. SIMMILAR WORK
Help-net japan
 Heavy investment from government to make it
successful
OnStar
 Monthly subscription

8. SYSTEM COMPONENTS
 Power supply
 Arduino uno microcontroller
 GSP module
 GSM Module
 Vibration sensor(impact detector)
 LCD display
 Limiting switch(reset button)

9. POWER REGULATION
 We used LM7805 and LM317 voltage regulator.
 To supply the system with the required power by
different components
Voltage requirement Gadget
9v Arduino uno R3
5V Vibration sensor & LCD
4,2 v Gps & GSM module
Supply voltage 12v from the car battery or
separate source

17. PROPOSED SYSTEM LOCATION
 We provide automotive
location system using GPS
and GPS technologies.

18. SYSTEM WORKING ……….
 STEPS
 System is powered and the operation starts.
 The Vibration sensor (impact detector )
readings monitored and any slight
acceleration analysed.
 The microcontroller in turn processes a
combination of the detected parameters and
executes.
 If the execution is a YES it excites a GPS
receiver to receive and convey the location of
the vehicle to the GSM module. Otherwise, a
NO returns control to the read Vibration
sensor (impact detector ) parameter to be
processed again.
 The GSM module is excited by the
microcontroller to send the location
coordinates to the information and vehicle
identification and alert emergency responders
,a follow up call is also initiated.

19. COMPARISON
 ADVANTAGES
 The vehicle involved in
accident can be
indentified without
delay
 Immediate emergency
medical assistance can
be provided to the
accident victims in
remote areas and at
night.
 DISADVANTAGES
though a rare
Some areas in the country
lack GSM coverage hence
difficult t for
communication of the
information

20. CONCLUSION
We designed a system at reduced cost compared to
existing systems.
The Gps coordinates we obtained with an accuracy of
+40 metres.
Project was successful and objectives achieved.

21. FUTURE SCOPE AND
ENHANCEMENT
wireless webcam can be added in this for capturing the images
 We propose research on how to better the system by locking all the brakes
automatically in case of accident. Mostly in accidents, it becomes serious as the drivers
lose control and fail to stop the vehicle. we can stop the vehicle and can weaken the
impact of the accident.
Our system can also be used in tracking stolen vehicles as well as fleet management in
big organizations hence helping reduce the in financial and time loss incurred by the
organisation.
 The accident alert system can be interfaced with the air bag system, which provides
security to the driver in case of an accident. track the vehicle in case of theft.
A warning light or a loud horn can be interfaced with the circuit which is turned on in
case of an accident, which draws the attention of the people nearby to the site of the
accident.
