Interesting Tasks on GTFS feeds data

[Emaasit]

These are some of the questions I would like to ask of the GTFS data. I am preparing functions for these.

1. Calculate a single trip fair: (to calculate the cost of a single trip, that is, boarding a vehicle, traveling for a number of stops, then disembarking)
2. Calculate trips with transfers: To take into account multiple trip segments (that is,one or more transfers)
3. Find trips departing a given stop
4. Find trips arriving at a given stop
5. Find trips between two stops

Sounds good - will take some work. If you could provide some code or pseudocode building on the reproducible example below that would help:

download.file("http://transitfeeds.com/p/bart/58/latest/download", "bart.zip")
unzip("bart.zip")
bart = stplanr::gtfs2sldf("bart.zip")
plot(bart)
fares = read.csv("fare_attributes.txt")
fare_atts = read.csv("fare_rules.txt")
head(fares)
head(fare_atts)

Closing for now as we're not working on it. Suggest doing this through an interface to OpenTripPlanner. This could either be within a package such as stplanr or gtfsr (as I suggested here) or, probably the best option, to create a new package, e.g. called rotp. Thoughts @richardellison?
