INTRODUCTION
1.1 Background
In the
developing countries like NEPAL, only small no of people have their private
vehicles. So, mostly people depend on local vehicles which charge their
customer as per the rate specified and distance travelled. These vehicles use a
specified device to display the distance travelled and the fare accordingly.
The device mainly used to measure in these vehicles is called taximeter. It
simply calculates the distance by calculating the number of rotation of wheel
and multiplying it with its circumference.
These vehicles
are owned by a specified person (owner) and they give it to someone they trust
to drive it who in return should submit the rent specified. The whole system
runs on the basis of trust. No exact data is available for any party to
evaluate each other. Local vehicles here are like the private vehicle of the
driver. Vehicle like taxies have a specified taxi fare assigned initially in
the device but they are never updated as the device has no connection with the
authority once they are installed. This creates problem in case of any need in
change of rate. For that the whole device has to be brought to the authorized
place and each need to be updated.
