Public Transit API

Connections

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

• connection(..., summary = FALSE): The public transport connections are returned as multiple sections with the same vehicle and transport mode. Each row represents a section with a detailed route geometry.
• connection(..., summary = TRUE): A summary of the connections is retrieved, where each connection is represented as one row with a unified and simplified geometry.

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

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

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

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
}
