2.  Figure shows the Number of Deaths from
Unintentional Injuries in 2012 given by WHO.

3.  According to official statistics 141,526 persons were killed and
477,731 injured in road traffic crashes in India in 2014 (NCRB,
2015).
 The actual numbers of injuries requiring hospital visits may be
20,000-30,000 persons.
 The situation in India is worsening and road traffic injuries
(RTI) have been increasing over the past twenty years
 This may be partly due to the increase in number of vehicles
on the road but mainly due to the absence of coordinated
evidence-based policy to control the problem.
 These data show that the number of fatalities has continued to
increase at about seven per cent a year over the past decade
except over the last couple of years

4. Exceeding lawful speed
Intake of alcohol / drugs
Overloading/overcrowding of vehicles
Defect in condition of motor vehicle
Defect in road condition
Lack of awareness about safe driving,
traffic/ safety discipline
Low level of literacy amongst the drivers
Diversion of Attention

5. Occurrence of
Accident
Victim becomes
unconscious and is
left unattended
Health and rescue
services reach late
Thereby receives help
by fellow passengers
Hospital admittance
procedure and
clearance of legal
documents
Victim looses
Precious time and his/
her health
deteriorates
Death

7.  Each module which is connected to LCU contains
a set of load cell sensor, microcontroller and
transmitter/receiver is installed on the street light
and is placed at the starting of the road.
 Each module counts the number of vehicles to
measure the traffic density
 Several such LCUs are connected to the MCU
which reports to the Main central Police Authority
and Hospitals in the vicinity.
 Retractable robots are placed at the ends of the
road.

9.  Two selectable differential input channels
 On-chip active low noise PGA with selectable gain of 32, 64
and 128
 On-chip power supply regulator for load-cell and ADC analog
power supply
 On-chip oscillator requiring no external component with
optional external crystal
 On-chip power-on-reset
 Simultaneous 50 and 60Hz supply rejection
 Current consumption including on-chip analog power supply
regulator: normal operation < 1.5mA, power down < 1uA
 Operation supply voltage range: 2.6 ~ 5.5V
 Operation temperature range: -40 ~ +85℃
 16 pin SOP-16 package

10. These robots are placed at the ends of the
road and help in blocking the further entry
of the vehicles in the accident zone.

11. The system can be enhanced further by advanced
using certain advanced technologies such as
 RFID encryption This prevents interference with
the transmitting RFID signal to Retractable Robot
 Electromagnetic Shielding This protects the
microcontroller board from incoming EMF
 Waterproofing solutions This protects the
microcontroller board from heavy rain
 Optical Fiber This can be used to transmit signals
faster and without any loss

13. JAVA PROGRAM FOR SIMULATING THE TRAFFIC CONDITIONS
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class traffic extends Applet implements Runnable
{
Thread t;
Font f,f1;
int i=0,a=0,j=0;
public void init(){set Background(Color.lightGray);
f=new Font("TimesNewRoman",f.ITALIC,28);
f1=new Font("TimesNewRoman",Font.ITALIC+Font.BOLD,28);}
public void start()
{t=new Thread(this);
t.start();}
public void run()
{for(i=25;i>=0;i--)//countdown
{try
{Thread.sleep(1000);}
catch(Exception e)
{System.out.println(e);}
if(i<=25 && i>3)//red
{a=1;
repaint();}
else
if(i<=3 && i>0)//yellow
{a=2;
repaint();}
else
if(i==0)//green
{for(j=0;j<25;j++)
{a=3; try
{Thread.sleep(1000);}
catch(Exception e)
{System.out.println(e);}
repaint();}
if(j==25)//end of green(return to red)
{ run();}}}
repaint();}

15. In remote areas, this system can be further
modified by means of using high quality
materials for the load cells to sustain
impact of the vehicle’s load on the
tarnished asphalt.
It can be used in left hand traffic as well as
right hand traffic,
Flyovers and Underground Tunnels.

16.  The above system was designed and created
on Arduino microcontroller platform
 The system was simulated on a JAVA Traffic
simulator where the code was written for
simulating the traffic conditions.
 The Graph of Traffic density vs time in the
traffic zone was plotted.
 Functionality of the system was proved
through simulation
