I want to analyze GTFS-realtime files using R, compared to the static GTFS, these files are compiled and reading them is trickier.
Googling around, I have only found this package to deal with GTFS https://github.com/ropenscilabs/gtfsr
But again, this is just for static GTFS.
Are you aware of a cran/github R package that deals with GTFS-realtime?
An alternative solution would be to convert the GTFS-RT into a more readable format like json streaming gtfs real time data into human readable format
I notice you already found your way over to my development package, gtfsway. In particular, the example in issue 1 gives an example of how the package works and the way it parses a realtime feed
devtools::install_github("SymbolixAU/gtfsway")
library(gtfsway)
url <- "https://gtfsrt.api.translink.com.au/Feed/SEQ"
response <- httr::GET(url)
FeedMessage <- gtfs_realtime(response)
## the function gtfs_tripUpdates() extracts the 'trip_update' feed
lst <- gtfs_tripUpdates(FeedMessage)
## The results will obviously change depending on when you read the data
lst[[32]]

I'm open to contributions & suggestions on the package if you have any.
