Calculate route between two points

Description

The route between two points is calculated for the given coordinates. The default values for rolling resistance and drag coefficient correspond to values found by Tengatti and Bigazzi (2018): Physical characteristics and resistance parameters of typical urban cyclists. brouterR ignores the bikerPower, totalMass, dragCoefficient, rollingResistance and maxSpeed available in the brouter routing profiles and uses the values provided via R instead. This functions needs the server to be set manually before running it with the setServers and then the startServers functions.

Usage

calculateRoute(
  startLat,
  startLon,
  endLat,
  endLon,
  bikerPower = 100,
  totalMass = 90,
  dragCoefficient = 0.559,
  rollingResistance = 0.0077,
  maxSpeed = 45,
  profile = "trekking",
  outputFormat = "df",
  serverNodeId = 1
)

Arguments

startLat	Latitude of start location
startLon	Longitude of start location
endLat	Latitude of end location
endLon	Longitude of end location
bikerPower	The total average power put on the pedals in Watts. Defaults to 100W
totalMass	The total weight of biker, bike and cargo in kg. Defaults to 90kg
dragCoefficient	The wind drag coefficient in m2. Defaults to 0.559
rollingResistance	The rolling resistance of the underground. Default value assumes dry asphalt, 0.0077
maxSpeed	The maximum speed achieved by the bike in km/h. Defaults to 45 km/h.
profile	Routing profile. Defaults to "trekking"
outputFormat	one of "df" or "linestring" (as an st_linestring object with XYZ dimensions). Defaults to "df"
serverNodeId	The node where the server is running on. Defaults to 1. Do not change for single core usage.

Value

Either a dataframe of the track (outputFormat="df"), or a st_linestring (outputFormat="linestring") containing elevation information
