get_speeds: Calculate Scheduled Speeds

In GTFSwizard: Creating, Exploring, and Manipulating GTFS Files

Calculate Scheduled Speeds

Description

Combines distance in meters and duration in seconds to calculate kilometers per hour.

Usage

get_speeds(gtfs, method = "by_trip", trips = "all")

Arguments

gtfs	A GTFS object.
method	One of '"by_trip"', '"by_route"', or '"detailed"'. Legacy dotted values remain accepted.
trips	Character trip IDs or '"all"'.

Details

Detailed distances are straight-line geodesic distances between stops. Route and trip distances follow 'shapes.txt', or inferred straight-line shapes if the feed has none.

Value

A tibble with 'average.speed' for route and trip methods, or segment-level 'speed' for the detailed method. 'direction_id' is retained when available.
