View source: R/get_trip_speed.R
Returns the speed of each specified trip_id
, based on the geometry
created from either on the shapes
or the stop_times
file (or
both).
1 | get_trip_speed(gtfs, trip_id = NULL, file = "shapes", unit = "km/h")
|
gtfs |
A GTFS object as created by |
trip_id |
A string vector including the |
file |
The file from which geometries should be generated, either
|
unit |
A string representing the unit in which the speeds are desired.
Either |
A data.table
containing the duration of each specified trip
and the file from which geometries were generated.
Please check get_trip_geometry
documentation to understand how
geometry generation differs depending on the chosen file.
