Metropolitan cities have the
largest population in our country. Many
people move out of their native places or
villages to cities owing to the numerous
benefits that cities can offer. Commutation
is one major advantage of urban life. The
number of private and public vehicles is
increasing year after year to match the
transportationneeds of the people. Every
vehicle will have emission but the problem
occurs when it is beyond the standardized
values.This emission from vehicles cannot
be completely avoided but, it definitely can
be controlled. The semi- conductor sensors
at the emission outlets of vehicles detect the
level of pollutants and a meter is used to
indicate this level. When the
pollution/emission level shoots beyond the
already set threshold level, there will be a
buzz in the vehicle to indicate that the limit
has been breached and the vehicle will stop
after a certain period of time, a cushion time
given for the driver to park his/her vehicle.
During this time period, the GPS starts
locating the nearest service stations. After
the timer runs out, the fuel supply to the
engine will be cut-off and the vehicle has to
be towed to the mechanic or to the nearest
service station. The synchronization and
execution of the entire process is monitored
and controlled by a micro controller. The
system with GPS is also used for the
security purpose. The GSM/GPRS modem
in this system receives the messages sent by
the user and replies for that message such as
locations etc. This paper, when augmented
as a real time project, will benefit the society
and help in reducing the air pollution and the
theft of vehicles.
