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
