3.  Automatic Speed Governing automatically controls
the speed of the vehicles at school and hospital zone
etc.
 To avoid accident of vehicles at speed limit zones.
 To help the passengers to cross the road safely
without facing any danger from high speed vehicles.
 This project can be used to avoid the rash driving of
the drivers.

4.  Every year, we find more and more road accidents due to
increased traffic on the roads.
 Nowadays people are driving very fast; accidents are
occurring frequently, we lost our valuable life by making small
mistake while driving (school zone, hills area, and highways).
 So this system can be used to avoid such kind of accidents
and to alert the drivers and to control their vehicle speed.
 The project is composed of two separate units: zone
transmitter unit and receiver unit.
 Once the information is received from the zones, the
vehicle’s embedded unit automatically reduce the speed
according to the zone.

6.  AT89C51 is the 40 pins, 8 bit Microcontroller
manufactured by Atmel group.
 The AT89C51 is a low-power, high-performance CMOS
8-bit microcontroller.
 It has 4kb on chip ROM and 128 bytes internal RAM
and 32 I/O pin as arranged as port 0 to port 3 each.
 All four ports in the AT89C51 are bidirectional.

8.  16x2 LCD(Liquid Crystal Display) electronic display
module is used here as display device.
 A 16x2 LCD means it can display 16 characters per line
and there are 2 such lines.
 This LCD has two registers , namely , Command and
Data registers.
 Economical, easily programmable, have no limitation of
displaying special &even custom characters.

9.  LCDs are used in a wide range of applications including
computer monitors, televisions.
 The LCD screen is more energy efficient than others.

10.  To provide power to the entire system.
 5v power supply is used for microcontroller and other
devices.

11.  GSM is a mobile communication modem; it is stands for
global system for mobile communication (GSM).
 GSM modem duly interfaced to the MC through the level
shifter IC Max232. The SIM card mounted GSM modem upon
receiving digit command by SMS from any cell phone send
that data to the MC through serial communication.

12.  Infrared technology addresses a wide variety of wireless
applications.
 The main areas are sensing and remote controls
 When the IR transmitter emits radiation, it reaches the
object and some of the radiation reflects back to the IR
receiver. Based on the intensity of the reception by the
IR receiver, the output of the sensor is defined.

13.  The term "DB9" refers to a common connector type, one
of the D-Subminiature or D-Sub types of connectors.
 DB9 has the smallest "footprint" of the D-Subminiature
connectors, and houses 9 pins (for the male connector)
or 9 holes (for the female connector).
 DB9 connectors were commonly used for serial
peripheral devices like keyboards, mice, joysticks, etc.
Also they are used on DB9 cable assemblies for data
connectivity.

14.  In our project to interface DC motor with microcontroller
we use L293D driver.
14

15.  The speed of the vehicle decreases automatically when
it reaches to the ZigBee range.
 We can control the over speed and rash driving of the
drivers.
 We can reduce the accidents and thus we can save
many lives and valuable properties.
15

16.  The cost of the system will be very less compared with
its application.
 To help the passengers to cross the road safely without
facing any danger from high speed vehicles.
 This system helps to avoiding the rash driving of the
drivers.
 The vehicle will move only with the designed speeds
corresponding to the zones
 The range of the IR transmitter is less which is 10m.
 This project consists of mechanical section, which is
difficult to implement
 It is difficult to control the airflow to the carburetor of the
vehicle.
16

17.  We can modify the system with the help of GPS to
identify the zones.
 We can also modify the system with efficient braking
system in association with air flow control to the
carburetor.
 This system can be more effectively used for any kind of
automobiles such as lorries, buses, cars, bikes etc.
17

18.  By using this system we can effectively control the speed
of the vehicle according to different zones.
 This system can be implemented in any kind of vehicles.
 By using this system we can control the over speed and
the rash driving of the drivers.
 We can use this system in highly populated regions and
thus we can decrease the effects of accidents.
