This document proposes a traffic guide system using wireless radio to help reduce traffic jams. It would work by transmitting guidance signals from access points using FM radio frequencies. Drivers' car radios would receive the signals on a reserved channel to guide them away from traffic jams. The system uses an FM microphone to transmit signals, a mini radio and PIC microcontroller to receive signals and control drivers' car radios to tune to the reserved channel. The PIC would switch the car radio on if off, change to the radio mode if on tape/CD, and tune to the police channel if on another station, guiding drivers away from jams.

IntroductionIntroduction
๏ฑ The aim of this project is to find a solution for traffic jam
problem
๏ฑ traffic jam can be reduced by guiding drivers where the
traffic jam is found. As a result driver could avoid going
through the traffic jam and use another way if it is
applicable.

๏ฑ This idea should be applied as collaboration with the
traffic police.
๏ฑ The information will be Transmit from access points
using FM in MHz.
๏ฑ The guiding process tool will be the car radio which will
be used as a receiver for the information that should
guide the drivers.

๏ฑ It is a form of modulation that represents
information as variations in the frequency of a
carrier wave.

๏ฑ Mini radio: It is tuned on (90) MHz to receive the transmitted signal, it
is used to give an indication to the PIC that there is a transmitted
signal from FM MIC.

PICPIC (Programmable Interface Circuit)(Programmable Interface Circuit)
๏ฑ The PIC is Programmed to do the following if there is a
guiding signal:
๏ If the radio is OFF, the radio status will be changed to be
ON.
๏ If tape, the PIC will change its mode to the radio mode.
๏ If the radio is tuned on any other channel, the PIC will
change the channel to the police guiding channel.

ConclusionsConclusions
๏ฑ The system reduces the traffic jam by guiding the drivers
to places away from jams.
๏ฑ The system is cheap and easy to be implemented in any
car
๏ฑ The use of the Microchip PIC microcontroller was
appropriate because it provides a good control basis
besides the ease of programming and using it.
