Contract OSRM Graph for Contraction Hierarchies (CH)

Source: R/osrm_contract.R
osrm_contract.Rd

Run the osrm-contract tool to contract an OSRM graph for the CH pipeline. After running, a companion <base>.osrm.hsgr file must exist to confirm success.

Usage

osrm_contract(
  input_osrm,
  threads = 8L,
  verbosity = c("INFO", "NONE", "ERROR", "WARNING", "DEBUG"),
  segment_speed_file = NULL,
  turn_penalty_file = NULL,
  edge_weight_updates_over_factor = 0,
  parse_conditionals_from_now = 0,
  time_zone_file = NULL,
  echo_cmd = FALSE,
  echo = TRUE,
  spinner = TRUE
)

Arguments

input_osrm

A string. Base path to the .osrm files (without extension).

threads

An integer. Number of threads to use; default 8.

verbosity

A string. Log verbosity level passed to -l/--verbosity (one of "NONE","ERROR","WARNING","INFO","DEBUG"); default "INFO".

segment_speed_file

A string or NULL. Path to nodeA,nodeB,speed CSV; default NULL.

turn_penalty_file

A string or NULL. Path to from_,to_,via_nodes,penalties CSV; default NULL.

edge_weight_updates_over_factor

A numeric. Threshold for logging large weight updates; default 0.

parse_conditionals_from_now

A numeric. UTC timestamp for conditional restrictions; default 0.

time_zone_file

A string or NULL. GeoJSON file for time zone boundaries; default NULL.

echo_cmd

A logical. Print each command before running; default FALSE.

echo

A logical. Stream stdout/stderr; default TRUE.

spinner

A logical. Show spinner instead of live logs; default TRUE.

Value

A list with elements:

osrm_path

The normalized path to the input .osrm base (invisibly). This can be passed over to osrm_start_server().

logs

The processx::run result object.
