could easily add more resources to do all kinds of queries on the MySQL database andprovide with the application with more data. I plan in the future to implement someuser feedback functionality in order to see how accurate the OCTranspo estimatesreally are.4.3 MySQL databaseI chose MySQL database because I had previous experience with installing it on myLinux machine. The reason a database was needed is that the OCTranspo data needsto be queryable and text les don't lend themselves well to such manipulation. FirstI downloaded the OCTranspo dataset from their website. It is in the GTFS formatwhich was created by Google. The General Transit Feed Specication is a commonformat for public transportation schedules and the associated geographic informationsuch as bus stop locations[5]. To parse all this plain text data I wrote a Python scriptto go through all the les dened by the GTFS, create tables necessary, and populatethem. The script is named octranspo_parse.py and is on the CD included with thisreport.28
5 Project ResultsThis project in my mind was a success. All the goals I had set at the beginning weremet and in the end I believe I was able to create a useful application which I useeveryday. I think the Android client is well designed, usable, and visually appealing.The application allows users to make better choices about when to leave home or theoce to catch a bus and limits the frustrations all have had with OCTranspo. Thedevelopment of the REST API allowed me to get a taste for developing web base APIswhich are highly concurrent due to their lightweight HTTP requests and responses.Using the location services provided by the Android platform gave me a niceintroduction to building applications that make use of the rich set of sensory dataprovided by modern smartphones. With location data, accelerometer, and axis, itis not hard to see the potential for rich user engaging applications. I believe I willattempt make at least one other application in the near future using one or more ofthese sensors.The backend of this project I think is suitable to be scaled in the future if desired.This would require replicating the MySQL database to run on multiple servers andsome kind of load balancer in front of a few TomCat servers for the API itself. I donot have any experience with this but from my limited knowledge of scalable websystems from tech blog readings this seems to be done often and is easily achieved bysomeone with the proper experience and knowledge.Once I had the application to a suitable level of usability I installed it on twoof my roomates' phones. After a few days of use they both reported that they wereextremely please with the application and that it had saved them from blindly headingto the stop hoping that the bus would actually arrive when scheduled. I was veryplease to see that something I had developed was helping real people by aiding them29
