time_filter_fast_proto {traveltimeR}

Time Filter (Fast) with Protobuf

Description

The Travel Time Matrix (Fast) endpoint is available with even higher performance through a version using Protocol Buffers. The endpoint takes as inputs a single origin location, multiple destination locations, a mode of transport, and a maximum travel time. The endpoint returns the travel times to each destination location, so long as it is within the maximum travel time.

Usage

time_filter_fast_proto(
  departureLat,
  departureLng,
  country = c("uk", "ireland"),
  travelTime,
  destinationCoordinates,
  transportation = names(protoTransport),
  useDistance = FALSE
)

Arguments

departureLat
