Get the Isochrones from a location
Usage
otp_isochrone(
otpcon = NA,
fromPlace = NA,
fromID = NULL,
mode = "CAR",
date_time = Sys.time(),
arriveBy = FALSE,
maxWalkDistance = 1000,
routingOptions = NULL,
cutoffSec = c(600, 1200, 1800, 2400, 3000, 3600),
ncores = max(round(parallel::detectCores() * 1.25) - 1, 1),
timezone = otpcon$timezone
)Arguments
- otpcon
OTP connection object produced by otp_connect()
- fromPlace
Numeric vector, Longitude/Latitude pair, e.g. `c(-0.134649,51.529258)`, or 2 column matrix of Longitude/Latitude pairs, or sf data frame of POINTS
- fromID
character vector same length as fromPlace
- mode
character vector of one or more modes of travel valid values "TRANSIT","BUS", "RAIL", "SUBWAY","TRAM", "FERRY", "GONDOLA", "FUNICULAR", "AIRPLANE", "CABLE_CAR", "WALK", "BICYCLE", "BICYCLE_RENT", "BICYCLE_PARK", "CAR", "CAR_PARK", "CAR_HAIL", "CARPOOL", "CAR_DROPOFF", "CAR_PICKUP", default CAR.

- date_time
POSIXct, a date and time, defaults to current date and time
- arriveBy
Logical, Whether the trip should depart or arrive at the specified date and time, default FALSE
- maxWalkDistance
maximum distance to walk in metres
- routingOptions
named list passed to OTP see `otp_routing_options()`
- cutoffSec
Numeric vector, number of seconds to define the break points of each Isochrone
- ncores
number of cores to use in parallel processing
- timezone
character, timezone to use, default from otpcon
Details
Isochrones are maps of equal travel time, for a given location a map is produced showing how long it takes to reach each location.
Isochrones are only available from OTP v1.x and will not work with v2.0
