The traveltime-package allows to retrieve isochrones for traveltime-maps from the Traveltime Platform API directly from R. The isochrones are stored as sf-objects, ready for visualization or further processing. The isochrones display how far you can travel from a certain location within a given timeframe. Numerous modes of transport are supported.
GET an API-KEY here: http://docs.traveltimeplatform.com/overview/getting-keys/
For non-commercial use the usage of the API is free for a restricted period of 10 days and can be granted for longer periods upon request.
You can install the traveltime-package with devtools or remotes from Github.
devtools::install_github("tlorusso/traveltime")
library(traveltime)
The traveltime_map function allows to easily retrieve traveltime-isochrones via the Traveltime-API.
# retrieve isochrones via request
The following transport modes are supported:
# "cycling"", "cycling_ferry", "driving", "driving+train", "driving_ferry", "public_transport",
# "walking", "walking+coach", "walking_bus", "walking_ferry" or "walking_train".
# how far can you go by public transport within 30 minutes?
traveltime30 <- traveltime_map(appId="YourAppId",
apiKey="YourAPIKey",
location=c(47.378610,8.54000),
traveltime=1800,
type="public_transport",
departure="YYYY-MM-DDT08:00:00Z")
# take a glimpse at the data
plot(traveltime30)
# or on top of a leaflet-map with mapview
mapview::mapview(traveltime30)
# You can switch to arrival search (from how far is a location reachable within x min?) just by using the 'arrival' argument instead of 'departure'.
traveltime30_arrival <- traveltime_map(appId="YourAppId",
apiKey="YourAPIKey",
location=c(47.378610,8.54000),
traveltime=1800,
type="public_transport",
arrival="YYYY-MM-DDT08:00:00Z")

In the upcoming version, further API-Modules will be supported.
