process_gtfs_local: process_gtfs_local

Description

Process a local GTFS data set with environmental variables described in go_home into a condensed version for use in go_home and go_to_work functions.

Usage

process_gtfs_local(expand = 2)

Value

No return value. The function saves processed data to a local cache.

Arguments

expand
