tidytransit (version 1.7.0)

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: .

Functions in tidytransit (1.7.0)

Example GTFS data

set_dates_services

Returns all possible date/service_id combinations as a data frame

set_servicepattern

sf_points_to_df

Adds the coordinates of an sf POINT object as columns

Calculate distances between a given set of stops

Convert shapes into Simple Features Linestrings

shape_as_sf_linestring

return an sf linestring with lat and long from gtfs

stop_group_distances

Calculates distances among stop within the same group column

Convert stops into Simple Features Points

summary.tidygtfs

GTFS feed summary

Calculate shortest travel times from a stop to all reachable stops

tidygtfs_to_gtfs

Convert a tidygtfs object to a gtfs object (for gtfsio)

Calculate travel times from one stop to all reachable stops

Convert stops and shapes from sf objects to tibbles

gtfs_to_tidygtfs

Convert an object created by gtfsio::import_gtfs to a tidygtfs object

Print a GTFS object

Adds the coordinates of an sf LINESTRING object as columns and rows

Write a tidygtfs object to a zip file

Validate GTFS feed

Convert an sf object to a json list

Cluster nearby stops within a group

empty_strings_to_na

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

filter_feed_by_date

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

filter_feed_by_area

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

Create a text listing the first max_agencies agencies of the feed

Convert another gtfs like object to a tidygtfs object

filter_feed_by_stops

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

get_route_geometry

Get all trip shapes for a given route and service

Get a set of stops for a given set of service ids and route ids

get_route_frequency

Get Route Frequency

get_stop_frequency

Get Stop Frequency

get_trip_geometry

Get all trip shapes for given trip ids

Convert stops and shapes to Simple Features

filter_stop_times

Filter a stop_times table for a given date and timespan.

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 in tidytransit's "calculated tables sublist" (gtfs_obj$.)

Convert columns between gtfsio types to tidytransit types according to GTFS reference

Plot GTFS stops and trips

Convert a json (read with jsonlite) to sf object

route_type_names

Dataframe of route type id's and the names of the types (e.g. "Bus")

hhmmss_to_seconds

Convert "HH:MM:SS" time strings to seconds (numeric) empty strings are converted to NA

interpolate_stop_times

Interpolate missing stop_times linearly

duplicated_primary_keys

Check if primary keys are unique within tables

hhmmss_to_sec_split

Fallback function to convert strings like 5:02:11 10x slower than hhmmss_to_seconds(), empty strings are converted to NA

Read and validate GTFS files

na_to_empty_strings

Convert NA values to empty strings ("")

Transform coordinates of a gtfs feed

Convert "HH:MM:SS" time strings to hms values empty strings are converted to NA
