fasttrips.TAZ

class fasttrips.TAZ(output_dir, gtfs, today, stops, transfers, routes)[source]

TAZ class.

One instance represents all of the Transportation Analysis Zones as well as their access links and egress links.

Todo

This is really about the access and egress links; perhaps it should be renamed?

Stores access link information in TAZ.walk_access, and TAZ.drive_access, both instances of pandas.DataFrame.

__init__(output_dir, gtfs, today, stops, transfers, routes)[source]: Constructor. Reads the TAZ data from the input files in input_archive.

Methods

`__init__`(output_dir, gtfs, today, stops, ...)	Constructor.

`warn_on_stops_without_walk_access`(stops)	Do any stops lack any walk access?
`write_access_egress_for_extension`(output_dir)	Write the access and egress links to a single output file for the C++ extension to read.
