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.
