list_validator_versions() which returns a df with the available CLI versions and their URLs. PR contribution by @baarthur
Notes

download_validator() now automatically detects the latest version available. PR contribution by @baarthur
gtfstools 1.4.0 (2025-01-08)
New features
download_validator() and validate_gtfs() now support using validator
v5.0.0, v5.0.1 and v6.0.0.
Notes
- Removed the local copies of
{cpp11} functions, as the most recent releases
fix the issues we were having.
gtfstools 1.3.0 (2024-10-07)
New features
- New function
convert_sf_to_shapes().
- New generic function
as_dt_gtfs() with methods for a few different classes
(tidygtfs, gtfs and list).
{gtfstools} functions now accepts GTFS objects created by other packages,
such as {gtfsio} and {tidytransit}.filter_by_route_type() now accepts Google Transit's extended route
types.
Thanks @Ge-Rag.convert_shapes_to_sf(), get_trip_geometry(), get_trip_length(),
get_trip_speed(), get_trip_segment_duration() and
get_stop_times_patterns() now take an additional argument sort_sequence,
used to indicate whether shapes/timetables should be ordered by
shape_pt_sequence/stop_sequence when applying the functions' procedures.download_validator() and validate_gtfs() now support using validator
v4.1.0 and v4.2.0.- New parameters to
filter_by_stop_id(): include_children and
include_parents.
Bug fixes
- Fixed a bug in
convert_to_standard() in which the date fields from
feed_info would not be converted back to an integer in their standard
format (YYYYMMDD).
- Filtering functions now also filter the
transfers table based on trip_id
and route_id. Previously they would filter it based only on stop_id.
Thanks Daniel Langbein (@langbein-daniel).
- Fixed a bug in
filter_by_route_id() in which feeds with only one agency
that omitted agency_id in routes and fare_attributes would end up with
an empty agency table.
filter_by_sf() now correctly throws an error when an unsupported function
is passed to spatial_operation.
Feature deprecation
- The
filter_by_stop_id() behavior of filtering by trips that contain the
specified stops has been deprecated. For backwards compatibility reasons,
this behavior is still the default as of the current version and is
controlled by the parameter full_trips. To actually filter by stop ids (the
behavior that we now believe is the most appropriate), please use full_trips = FALSE. This behavior will be the default from version 2.0.0 onward. To
achieve the old behavior, manually subset the stop_times table by stop_id
and specify the trip_ids included in the output in filter_by_trip_id().
filter_by_sf() has been deprecated in favor of
filter_by_spatial_extent(). For backwards compatibility reasons, usage of
filter_by_sf() is still allowed as of the curent version, but the function
will be removed from the package in version 2.0.0.
Notes
validate_gtfs() now defaults to run sequentially. Previously it would
default to run parallelly using all available cores. Heavily inspired by
Henrik Bengtsson post "Please Avoid detectCores() in your R packages"
(https://www.jottr.org/2022/12/05/avoid-detectcores/).- Improved performance of
seconds_to_string() and, consequently, any other
functions that use it.
- Improved performance and improved readability of most filtering functions.
gtfstools 1.2.0 (2022-11-24)
New features
- New
validate_gtfs() behavior. Now used to run MobilityData Canonical GTFS
validator with a feed. The old behavior was marked as deprecated since
v1.0.0.
- New function
download_validator().
- New vignette demonstrating how to validate feeds.
Bug fixes
- Fixed a bug in
write_gtfs() that prevented as_dir = TRUE to be used.
- Fixed a bug in
set_trip_speed() that resulted in invalid stop_times tables
when max(stop_sequence) was higher than the number of stops of a given
trip. Thanks Alena Stern (@alenastern).
- Fixed a bug in
set_trip_speed() that resulted in the speed of wrong
trip_ids being updated because of the order that these ids would appear in
the trips and stop_times tables. Thanks Alena Stern (@alenastern).
gtfstools 1.1.0 (2022-05-24)
New features
- New function
convert_time_to_seconds().
- New function
filter_by_agency_id().
- New function
filter_by_service_id().
- New function
filter_by_time_of_day().
- New function
filter_by_weekday().
- New function
frequencies_to_stop_times().
- New function
get_children_stops().
- New function
get_stop_times_patterns().
- New function
get_trip_length().
- New parameter to
merge_gtfs(): prefix. The warnings parameter was flagged as deprecated.
- Functions
get_parent_station() and get_children_stops now accept stop_id = NULL to analyze all stop_ids in the stops table.
Bug fixes
- Fixed a bug in which
get_trip_segment_duration() would list wrong segment numbers, not necessarily starting from 1. Now segment numbers always range from 1 to N, where N is the total number of segments that compose each trip.
- Fixed a bug in
filter_by_{route,service,shape,trip}_id() that resulted in the agency table not getting filtered when the specified id was character(0).
Notes
- Performance improvements to
get_trip_geometry(), get_trip_duration(), get_trip_segment_duration() and convert_shapes_to_sf().
- Stopped ordering points by
shape_pt_sequence/stop_sequence in get_trip_geometry() and convert_shapes_to_sf(), since the GTFS reference says that the stop_times and shapes tables must be ordered by point/stop sequence anyway.
- Removed
{lwgeom} from dependencies (Suggests), now that it's not required to run get_trip_speed() and set_trip_speed() anymore.
- Removed the
warnings parameter from read_gtfs() and write_gtfs() and the optional and extra parameters from write_gtfs(), flagged as deprecated on gtfstools v1.0.0.
- Updated filtering vignette to demonstrate new functions.
gtfstools 1.0.0 (2021-11-16)
New features
- New function
convert_stops_to_sf().
- New function
convert_shapes_to_sf().
- New function
filter_by_route_type().
- New function
filter_by_route_id().
- New function
filter_by_sf().
- New function
filter_by_shape_id().
- New function
filter_by_stop_id().
- New function
filter_by_trip_id().
- New function
get_parent_station().
- New function
remove_duplicates().
- New parameters to
read_gtfs(): fields, skip and encoding. The warnings parameter was flagged as deprecated.
- New parameters to
write_gtfs(): files, standard_only and as_dir. They substitute the previously existent optional and extra, which were flagged as deprecated. The warnings parameter was flagged as deprecated too.
- New vignette exploring the filtering functions.
Bug fixes
get_trip_speed() and set_trip_speed() examples and tests now only run if {lwgeom} is installed. {lwgeom} is an {sf} "soft" dependency required by these functions, and is listed in Suggests. However, package checks would fail not so gracefully if it wasn't installed, which is now fixed.- Fixed a bug in which the
crs passed to get_trip_geometry() would be assigned to the result without actually reprojecting it.
- Changed the behaviour of
get_trip_geometry() to not raise an error when the 'file' parameter is left untouched and the GTFS object doesn't contain either the shapes or the stop_times table. Closes #29.
- Fixed a bug that would cause
merge_gtfs() to create objects that inherited only from dt_gtfs (ignoring gtfs and list).
- Fixed a bug in which
get_trip_speed() returned NA speeds if the specified trip_id was listed in trips, but not in stop_times.
- Adjusted
set_trip_speed() to stop raising a max()-related warning when none of the specified trip_ids exists.
Notes
- Some utility functions previously provided by
{gtfs2gps} will now be exported by {gtfstools}. Huge thanks to the whole {gtfs2gps} crew (Rafael Pereira @rafapereirabr, Pedro Andrade @pedro-andrade-inpe and João Bazzo @Joaobazzo)!
- The package now imports
{gtfsio}, and many functions now heavily rely on it, such as read_gtfs() and write_gtfs().
- Internal function
string_to_seconds() now runs much faster thanks to Mark Padgham (@mpadge).
get_trip_geometry() now runs much faster due to data.table-related optimizations.
Potentially breaking changes
- Functions no longer validate GTFS objects on usage.
validate_gtfs() will be flagged as deprecated as well, since I plan to heavily change its usability and outputs in future versions.
write_gtfs() parameters went through major changes - the optional and extra params were flagged as deprecated and substituted by the more general files and standard_only.
