Bus data study
Group 2
Shikun D., Wonyong H., Luit S.
Introduction/Motivation

The goal of our project includes study and analyzes IU bus data.

We obtained the data from professor Predrag Radivojac, IU bus (Logan as
representative) and IU bus website

In this presentation we will show:
1.
How many people using bus data in different time
2.
passenger change by month/day (in considering of semester begin,
breaks, ending, drop class etc. )
3.
How snow/rain weather affect above info
4.
Relation between how many people take certain bus(identified ID) and
how long or how many days that bus runs
5.
Which bus driver take most/least passengers (Are they over count
passenger? Or less count passenger number?)
6.
Which bus driver in average take most passenger (average means per
hours)
Data example
We have 666754 data points like this
15*(10^6) s
=173.6 days
A more visible plot to out data

According to raw data, the total operation time (include bus all travel, wait time) is
251672197 seconds (about 4194536 minutes or 69909 hours or 2913 days).

Filter data based on time difference

There are totally 26 busses.

If set limit to 900. Then each bus run about 19.41 days during 4 months

Average running time for each bus based on time filter

Snow data analyze

% The number of passengers who take bus on snow days is much
more than other days

% 3044 more than all days, in average (27.71%)

% 3463 more than only rain days, in average (32.77%)

% Hypothesis:

% Many students who have car tend to take bus in snow weather
cause their car can't run in extreme cold weather

% Low base cars (small cars) can't run in heavy snow weather.
(SUVs and buses with higher base level can run)

% It is harder for people to walk in snow than rain/sunny days
% At least one
rain in 30 days
%3

Driver data Analyze

% Driver K. 497.6344 passenger per hour in average. Clocked in
9:18:00 and took 4628 passenger (May be over count passenger)

% Driver M. 8.0986 passenger per hour in average. clocked in
225:06:00 and took 1823 passengers (May be under count passenger)

% For all drivers, there are 1395086 passengers. Each driver took
19111 passenger

% in average. In sum, drives worked for 7220 hours. 1395086/7220 =
193.2252

% Thus, in average, drivers can take 193.22 passenger during 1 hour of
work.
Conclusions/Results

Each bus runs about 19.41 days (465.85 hours) during 4 months (Exclude issue
time such as broken, or extreme traffic issue). Actual data show 19-23 days.

Average number of passengers per 4-5 minutes: A: 47.46, B: 33.5, E: 33.1, X:
21.1461



Min number of passenger Per 5 mins A:6
B:2
E:4
X:0

Passengers for route A > B > E

Rainy day and normal days about same number of passengers.

Snow weather cause more people taking bus (around 28%)

Busy time: A: 8:00 AM, 10:00 AM B: 11:00 Am, 12:00 PM, E: 9:30 AM, 11:00 AM,

X: 9:00 AM, 12:00 PM, 3:00 PM. All fast come fast gone peaks.

Continues load time (less than peak but last longer) 5:00 PM, 7:00 PM.

Add more bus during above time.

In average, drivers take 193.22 passenger in 1 hour of work.
Future work

Finding out who is the best driver. (Arrive bus stops on
time mostly)

How temporary driver’s drive patters (counting passenger,
arrive on time) different than other drivers.

Calculate bus run efficiency in different time. (Number of
passenger/how many bus run at that time)
