Public Transit API

Request public transport connections between given points and find stations nearby using the ‘HERE Public Transit’ API.

Connections

The function connection() allows to request public transport connections from the API. Two types of requests are provided:

1. Sections

Request available public transport connections as detailed sections:

connection_section <- connection(
  origin = poi[3:4, ],
  destination = poi[5:6, ],
  summary = FALSE
)

The id column corresponds to the row of the input locations (origin and destination) and the rank column enumerates the alternative routes. The maximum number of alternatives can be set by the results parameter. Each row in the returned sf object corresponds to a route section with a transport mode in a vehicle without a transfer.

Print the public transport sections on an interactive leaflet map:

if (requireNamespace("mapview", quietly = TRUE)) {
  mapview::mapview(connection_section,
    zcol = "mode",
    layer.name = "Transport mode",
    map.types = c("Esri.WorldTopoMap"),
    homebutton = FALSE
  )
}

2. Summary

Request a summary of the available public transport connections:

connection_summary <- connection(
  origin = poi[3:4, ],
  destination = poi[5:6, ],
  summary = TRUE
)
id rank departure origin arrival destination transfers modes categories vehicles providers distance duration

Stations

The function station() allows to request public transport stations nearby points of interest (POIs). The radius defines the maximum search distance in meters and results specifies the maximum number of returned stations. The returned sf object contains the locations of the stations and the available public transport lines at the station.

stations <- station(
  poi = poi,
  radius = 500,
  results = 5
)

Print the POIs, the radius and stations on an interactive leaflet map:

buffer <-
  poi %>%
  st_transform(2056) %>%
  st_buffer(500) %>%
  st_transform(4326)

if (requireNamespace("mapview", quietly = TRUE)) {
  m <-
    mapview::mapview(poi,
      alpha.region = 1, col.region = "black",
      label = poi$city, layer.name = "POIs",
      map.types = c("Esri.WorldTopoMap"), homebutton = FALSE
    ) +
    mapview::mapview(stations,
      col.region = "yellow", alpha = 1,
      label = stations$station, layer.name = "Stations",
      homebutton = FALSE
    ) +
    mapview::mapview(buffer,
      col.region = "transparent", alpha.region = 0,
      layer.name = "Buffer", homebutton = FALSE, legend = FALSE
    )
  m
}
