Abstract: Good public transport facility is
very essential for quality life in cities. The allied
information like proper display of time tables
of such facility is a basic need of commuters. In
this article an attempt is made to use a simple
but effective statistical tool viz. Stem and Leaf
chart for this purpose. This type of display at
every city bus stop will be very useful.

I. INTRODUCTION
Public transport of a city is like a nervous
system of human body. Hence poor public
transport leads to hurdle in the growth of the city.
Pune city is very well known as the Oxford of
East, an auto industry hub and an IT industry hub.
Thousands of people relocate to Pune for higher
education and good jobs. Consequently the
population of Pune has increased exponentially
during last few years. Housing has become very
costly so people have to stay at such places
which are far away from their work place. So
travelling is an integral and unavoidable part of
day to day life. Even school going children have
to travel long distances daily. To cater this need,
city requires a strong public transport system,
preferably city bus, local trains, metro etc.
In Pune and suburbs PMPML (Pune
Mahanagar Parivahan Mahamandal Limited)
provides bus service through 365 routes having
around 22,000 trips per day. PMPML buses run
from Manjari to Hinjwadi in east-west direction
and from Katraj to Vishrantwadi in south-north
direction. About 10 to 12 lakh people depend
on this facility for commuting. Generally these
include senior citizens, lower middle class people
and school and college students. Unfortunately,
it is the general public opinion that PMPML
service is not so efficient.
