⚠️There's a newer version (1.7.0) of this package.Take me there.

tidytransit (version 1.4)

Read, Validate, Analyze, and Map GTFS Feeds

Description

Read General Transit Feed Specification (GTFS) zipfiles into a list of R dataframes. Perform validation of the data structure against the specification. Analyze the headways and frequencies at routes and stops. Create maps and perform spatial analysis on the routes and stops. Please see the GTFS documentation here for more detail: .

summary.tidygtfs

GTFS feed summary

stop_group_distances

Calculates distances among stop within the same group column

Calculate distances between a given set of stops

empty_strings_to_na

Convert empty strings ("") to NA values in all gtfs tables

filter_feed_by_area

Filter a gtfs feed so that it only contains trips that pass a given area

filter_feed_by_date

Filter a gtfs feed so that it only contains trips running on a given date

filter_feed_by_stops

Filter a gtfs feed so that it only contains trips that pass the given stops

filter_stop_times

Filter a stop_times table for a given date and timespan.

convert_times_to_hms

Convert time columns to hms::hms in feed

filter_feed_by_trips

Filter a gtfs feed so that it only contains a given set of trips

Returns TRUE if the given gtfs_obj contains the table. Used to check for tidytransit's calculated tables in sublist (gtfs_obj$.)
