fasttrips.Transfer

class fasttrips.Transfer(input_archive, output_dir, gtfs_feed)[source]

Transfer class.

One instance represents all of the Transfer links.

Stores transfer link information in Transfer.transfers_df, an instance of pandas.DataFrame.

__init__(input_archive, output_dir, gtfs_feed)[source]: Constructor. Reads the gtfs data from the transitfeed schedule, and the additional fast-trips transfers data from the input files in input_archive.

Methods

`__init__`(input_archive, output_dir, gtfs_feed)	Constructor.
`add_numeric_stop_id`(stops)	Stops are now equipped to add numeric ID (DAPs are in) so grab them
`add_transfer_attributes`(transfer_links_df, ...)	Adds transfer attributes for transfer links and returns those transfer links with the additional columns.
`write_transfers_for_extension`()	This writes to an intermediate file a formatted file for the C++ extension.

Attributes

`INPUT_TRANSFERS_FILE`	File with fasttrips transfer information (this extends the gtfs transfers file).
`OUTPUT_TRANSFERS_FILE`	File with transfer links for C++ extension It's easier to pass it via file rather than through the initialize_fasttrips_extension() because of the strings involved
