11. DATA VALIDATION

12. -removes entries with extra decimal points.
QUERIES
select span from routeatlas where span like ('%.%.');
-removes entries with extra decimal points.
select time from route_at where time similar to '%([a-z]|[A-Z])%';
-checks for random strings in the ‘time’ column.

13. JOINING THE TABLES

14. We applied ‘SOUNDEX’ algorithm to join Route Atlas with Route Master.

16. GTFS

17. WHAT IS GTFS?
A data standard developed by Google used to describe a public transportation system.
WHY GTFS?
We are using gtfs as it is a standard tool used by many API’s like OTP.

18. Structure of GTFS Agency_id Agency_name Agency_url Timezone Stops.txt:
Collection of csv files with .txt format.
Agency.txt:
Agency_id
Agency_name

Stops.txt:
Stop_id
Stop_name
Stop_lat

19. Routes.txt:
Route_id

22. PLAYING WITH API’s

23. GTFS TOOLS
There are many API’s that use gtfs feed as source and help in routing and scheduling possible easily.
Some of them are open-trip- planner,Graphhopper,
Timetablepublisher etc.

24. DEPLOYING OTP

25. WHAT IS OPEN TRIP PLANNER?
An open source platform for multi-modal and multi-agency journey planning.
OTP relies on open data standards including GTFS for transit and OpenStreetMap for street networks.
Requirements :
GTFS .
.osm file of city

26. How to deploy OTP?
For depoloying otp, you have to follow just 3 steps:
Install an otp instance (or jar file) in the respective directory containing .osm file and gtfs.
Form the graph.obj file.
Run the following command :
java -Xmx2G -jar otp shaded.jar –build /home/username/otp --inMemory

30. NEW FUNCTIONALITIES ADDED

31. FUTURE SCOPE

32. New data models for incorporating data for shelter codes .
Android app for the project.
Updating all the variants of chalobest.in website like dev.chalobest.in,chalobest.in/sta ts etc.
Extending the GTFS to include other optional files also like Frequencies.txt
Giving data about transfer points in the gtfs by means of transfers.txt
