Usage

calc_evac_time(distance_m, walking_speed_mps = 1.22, units = "minutes")

Arguments

distance_m

walking_speed_mps

Walking speed in meters per second. The paper-style default is 1.22 m/s, but this should be changed for local planning scenarios.

units

Output units: "minutes", "seconds", or "hours".

Value

Numeric vector of evacuation times.

Examples

calc_evac_time(c(0, 120, 240), walking_speed_mps = 1.2)
