edit_speed: Scale In-Vehicle Travel Speed

In GTFSwizard: Creating, Exploring, and Manipulating GTFS Files

Scale In-Vehicle Travel Speed

Description

Changes travel time between consecutive stops by dividing it by a speed multiplier. Dwell times are preserved and all downstream times are shifted.

Usage

edit_speed(gtfs, trips = "all", stops = "all", factor)

Arguments

gtfs	A GTFS object.
trips	Character trip IDs or '"all"'.
stops	Character stop IDs or '"all"'. A segment is edited when either endpoint is selected.
factor	One positive speed multiplier. For example, '2' halves segment travel times.

Value

A modified 'wizardgtfs' object.
