v2.0-0

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.

v1.5-4

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

v1.5.0

gtfs2gps v1.5.0

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.

v1.4.0

---

gtfs2gps 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
