+ \item Data about busses is difficult to get
+ \item Suspicion that privatisation may make it worse
+ \item \ldots or not?
+ \item Questions
+ \begin{itemize}
+ \item Will it?
+ \item Is the 370 actully the worst
+ \end{itemize}
+ \item Lot of data from TfNSW, nothing useful
+ \item The data exists at least in Grofsoft's TripView app
+ \item General Transit Feed Specification (GTFS) by Google
+ \item Historical data is hard to get $\rightarrow$ collected real-time data
+ for 4 months (1--10MiB per minute, 557GiB total)
+ \item Analysis in EC2, annoying to relink and clean CSV files
+ \item What does it mean for a bus to be the worst?
+ \begin{itemize}
+ \item NSW's KPI for being on time (for third parties): $[-1:59,5:59]$\,min at
+ beginning and end of the trip
+ \item VIC: bus should never run early, nor 5\,min late at any point in the
+ trip
+ \item chosen metric: no more than 2\,min early, nor 5\,min late
+ \end{itemize}
+ \item Results
+ \begin{itemize}
+ \item 3.726.226 bus trips
+ \item 31\% were on time
+ \item 2.86\% were more than 20\,min late
+ \end{itemize}
+ \item Best busses
+ \begin{itemize}
+ \item Night busses run the best
+ \item Longer routes are much less reliable
+ \end{itemize}
+ \item Worst busses
+ \begin{itemize}
+ \item 370 not it the top-10 worst for NSW (22nd)
+ \item 370: 6th by more than 20\,min late
+ \item on-time 370s are outliers
+ \end{itemize}
+ \item Worst agencies
+ \begin{itemize}
+ \item Hillsbus 1st
+ \item STS 5th worst
+ \end{itemize}
+ \item Conclusion
+ \begin{itemize}
+ \item Privitisation could go either way
+ \item 370 is the worst route as it's well placed on both worse lists
+ \end{itemize}
+ \item Future work
