== Introduction ==
High performance routing engine written in C++14 designed to run on OpenStreetMap data.    [https://github.com/Project-OSRM/osrm-backend <sup>1</sup>]
== Installed version(s) ==
The following versions are installed and currently available... <br/>

... on environment ''hpc-env/8.3'':

*'''osrm-backend/5.25.0'''-foss-2019b
*'''osrm-backend/5.26.0'''-foss-2019b
*'''osrm/3.4.1'''-foss-2019b-R-4.1.0-2021.06   ### osrm includes osrm-backend as loaded module
*'''osrm/3.5.1'''-foss-2019b-R-4.1.0-2021.06

== Loading / Using osrm-backend==
To load the desired version of the module, use the ''module load'' command, e.g.

 module load hpc-env/8.3
 module load osrm

Always remember: this command is case sensitive!

The osrm module loads osrm-backend aswell, but osrm itself includes the following R packages:
*GISTools
*googlePolylines
*ibdreg
*osrm
*osrmr
*plm
*rgeos
*s2
*spd
*spdep
*splm
*wk 

<br>
osrm-backend provides different executables, namely  <tt>osrm-components,  osrm-contrac,t  osrm-customize,  osrm-datastore,  osrm-extract,  osrm-io-benchmark,  osrm-partition, </tt> and  <tt>  osrm-routed </tt> </br>

To find out on how to use the executables,  you can just call most of the executables without any arguments to print out a help text to get you started.

$ osrm-contract
Usage: osrm-contract <input.osrm> [options]:

Options:
  -v [ --version ]                      Show version
  -h [ --help ]                         Show this help message
  -l [ --verbosity ] arg (=INFO)        Log verbosity level: NONE, ERROR, 
                                        WARNING, INFO, DEBUG

Configuration:
  -t [ --threads ] arg (=24)            Number of threads to use
  -k [ --core ] arg (=1)                DEPRECATED: Will always be 1.0. 
                                        Percentage of the graph (in vertices) 
                                        to contract [0..1].
  --segment-speed-file arg              Lookup files containing nodeA, nodeB, 
                                        speed data to adjust edge weights
  --turn-penalty-file arg               Lookup files containing from_, to_, 
                                        via_nodes, and turn penalties to adjust
                                        turn weights
  -o [ --level-cache ]                  DEPRECATED: Will always be false. Use 
                                        .level file to retain the contraction 
                                        level for each node from the last run.
  --edge-weight-updates-over-factor arg (=0)
                                        Use with `--segment-speed-file`. 
                                        Provide an `x` factor, by which 
                                        Extractor will log edge weights updated
                                        by more than this factor
  --parse-conditionals-from-now arg (=0)
                                        Optional for conditional turn 
                                        restriction parsing, provide a UTC time
                                        stamp from which to evaluate the 
                                        validity of conditional turn 
                                        restrictions
  --time-zone-file arg                  Required for conditional turn 
                                        restriction parsing, provide a geojson 
                                        file containing time zone boundaries
