5.2Recommendations
In case of the system being rolled out in a country, mapping polygons may be replaced with
wireless antennas placed in different speed zones. Such that the critical speed adjusts according
to the signal received. Also other of the capabilities of the GPS receiver like vehicle tracking
could also be incorporated.
5.3 conclusion
The GPS receiver obtained the speed of the vehicle and assigned the speed limits according to
the mapped areas. The LCD displayed the speed limits and the current speed of the vehicle. If
the speed limit was exceeded, the LCD would print a message warning the driver to slow down
and if the vehicle did not slow down, a text message with the details of the vehicle would be
sent via the GSM shield to a database. Also an SMS containing the fine charged was sent to the
owner of the vehicle.
