\usage{
process_gtfs_local(expand = 2)
}
\arguments{
\item{expand}{The data set is reduced to the bounding box defined by the
home and work stations, expanded by this multiple. If the function appears to
behave strangely, try re-running this function with a higher value of this
parameter.}
}

}
\description{
Process a local GTFS data set with environmental variables described in

\code{go_to_work} functions.

# For general use, please set these three variables:
Sys.setenv ("gtfs_home" = "<my home station>")
Sys.setenv ("gtfs_work" = "<my work station>")
Sys.setenv ("gtfs_data" = "/full/path/to/gtfs.zip")

# The following illustrate use with sample data bundled with package
Sys.setenv ("gtfs_home" = "Tempelhof")
Sys.setenv ("gtfs_work" = "Alexanderplatz")
