Our project describes the implementation of a real
time passenger information system for a public
transport system.

RTPIS technology can be applied to public transport
systems.
A RTPIS uses a variety of technologies to track the
locations of buses in real time.
This information generates the predictions of bus
arrivals at stops along the route.
The vehicle unit reports the current position to a
central server periodically via GPRS.

The information is displayed to passengers at stops usingstation units.

MSP430
Ultra-low-power microcontroller.
Achieve extended battery life.
GPS
Provides location and time information.
ENCODER
It converts information from one format or code to
another.
saves space by shrinking size.

DECODER
Reverse operation of an encoder.
It is a combinational circuit.
LCD
A liquid crystal display is a thin,flat display device.
RF TRANSMITTER
Generation of a carrier signal.
Contain only a continuously running
oscillator coupled to some antenna system.

RF RECEIVER
It operates at a frequency of 434 MHz.
MONITOR
The command for the control will be
given to the microcontroller using PC.

Automated operation.
Low power consumption.
No need to remember all public, private
transportation contact numbers.
Highly reliable.
DisadvantagesInitial implementation requires high cost.
Lack of availability of detailed map of allregions.

We have developed a RTPIS that tracks the current
location of all the buses and estimates their arrival time
at different stops in their respective routes.
Estimates are updated every time the bus sends an
update.
It distributes this information to passengers using
display terminals at bus stops, web based GUI and
SMS.
