get_trip_speed {gtfstools} | R Documentation |
Get trip speed
Description
Returns the speed of each specified trip_id
, based on the geometry created
from either the shapes
or the stop_times
file (or both).
Usage
get_trip_speed(gtfs, trip_id = NULL, file = "shapes", unit = "km/h")
Arguments
gtfs |
A GTFS object, as created by |
trip_id |
A character 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 |
Value
A data.table
containing the duration of each specified trip and the
file from which geometries were generated.
Details
Please check get_trip_geometry()
documentation to understand how geometry
generation differs depending on the chosen file.
