In gtfs2gps: Converting Transport Data from GTFS Format to GPS-Like Records

log history of gtfs2gps package development

gtfs2gps v2.1-0

• Major changes
• Filter functions were removed from the package because gtftools alredy implements them
• Function gtfs2gps now uses parallel = TRUE by default.

• Function gtfs2gps now uses gtfstools::frequencies_to_stop_times() to convert. frequency-based GTFS feeds to stop times before processing the data.

• Minor changes

• New argument quiet to gtfs2gps()
• Removed readr, pbapply, lwgeom and magrittr from package dependencies.

gtfs2gps v2.0-3

• Minor changes
• Saving units when using argument filepath in gtfs2gps().

gtfs2gps v2.0-1

• Major changes

• Imports gtfstools package.

• Minor changes

• Fixing CRAN error and warning related to the vignette.
• The function adjust_speed() now does not change very low speed (1.000000e-12 [km/h]) because these values indicate a situation of a stopped vehicle. Closed 249.

gtfs2gps v2.0-1

• Minor changes
• gtfs2gps() now prints a message alerting if there are any trips with negative speed values in the output. Closes #172.
• Fixing small bugs in the output of gtfs2gps().

gtfs2gps v2.0-0

• Major changes
• gtfs2gps() now creates two points for a stop when arrival and departure exist. Speed and travel time are now calculated considering both departure_ and arrival_time columns.
• The travel statistics in the output table (speed, dist, cumdist, cumtime) for a given point are now calculated in relation to the previous point. More details in the documentation of the gtfs2gps() function.
• Names of the output columns of gtfs2gps() were updated
• New function adjust_arrival_departure() to allow users set a minimum time for dis/embarking times at each stop.
• New function adjust_speed() to fix outlier speeds and replace missing speed values with a speed set by the user or the average speed of the system. The timestamp values are updated accordingly.
• Fixing several small errors in the output of gtfs2gps(), what breaks compatibility with previous versions of the gtfs2gps package.

gtfs2gps v1.5-4

• Major changes
• Fixed CRAN bugs
• Fixed small bug that prevented creating departure times correctly

gtfs2gps v1.5

• Major changes
• Fixed the update of trip_number attribute. This affects the output of gps_as_sflinestring(). Closes #189.
• Imports the gtfsio package, used in the read_gtfs() and write_gtfs() functions. Closes #191.

• New parameter snap_method added to gtfs2gps().

• Minor changes

• Function filter_single_trip() now also filters the stop_times table. Closes #195.
• Change default spatial_resolution of gtfs2gps() from 50m to 100m. Closes #202.

gtfs2gps dev v1.4-0

• Major changes
• Allows filtering a GTFS feed by weekday and accounts for calendar_dates.txt info. Closes #103, #124 and #141
• New sample GTFS.zip data for Berlin
• New compress parameter in gtfs2gps function so that users can save the function outputs in compressed .RDS format.
• New function remove_by_route_id() to remove GTFS data by route ids. Closes #180

• Stops are now snapped to shapes using a simpler and more restrictive algorithm. This help identifies when a route is has problem with stop_sequence in the wrong order

• Minor changes

• Fixed a bug in filter_day_period. Closes #96
• Fix the treatment of midnight trips. Closes #43
• Fix linebreak gps_as_sflinestring. Closes #171
• Warnings are now printed as messages
• Order stop sequence before converting to GPS.
• Additional verifications in gtfs2gps
• Added package Hex sticker Closes #75

gtfs2gps v1.3-2

• Major changes
• New function to merge GTFS feeds. Closes #34
• New pkgdown website. https://ipeagit.github.io/gtfs2gps/ . Closes #146

• Distance of 1st point of GPS trip now start with distance zero. Closes #136

• Minor changes

• changes parallel execution to conform new future standards. closes #55
• Improve time filter in filter_day_period. Closes #89 and 147
• Improved documentation of spatial_resolution parameter. Closes #116

gtfs2gps v1.3-0

• Major changes
• Use progress bar from progressr. Closes #142
• Handling units of measurement
• Speeding up some algorithms

gtfs2gps v1.2-1

• Minor changes
• Allowing to read gtfs files without calendar/agency
• New verifications to create a better feedback for the user

gtfs2gps v1.2-0

• Major changes
• Processing mixed detailed and frequency-based GTFS files
• Small changes in gps_as_sflinestring() due to new GDAL
• Function to simplify shapes

gtfs2gps v1.1-0

• Major changes
• New function append_height(), to create height column to GPS data
• Update related to the newest versions of lwgeom and sf (#112)
• Replacing sf_multipoint by sf_point in gps_as_sf() to keep all the data

gtfs2gps v1.0-7

• Minor changes
• Removing bugs found by CRAN automatic tests

gtfs2gps v1.0-5

• Launch of gtfs2gps v1.0-5 on CRAN on 2020-03-16
