Check conditional restrictions

WARNING!

osrm-extract-conditionals deprecated since begin of 2018. Now proper commands are:

osrm-extract --parse-conditional-restrictions
osrm-contract --parse-conditionals-from-now 1517908115 --time-zone-file tz.json

For more information see: https://github.com/Project-OSRM/osrm-backend/issues/4852

Preconditions

The tool osrm-extract-conditionals requires Boost library version 1.61, Shapefile library that can be installed as

sudo apt install libshp-dev

and OSRM configured with BUILD_TOOLS

cmake -DBUILD_TOOLS=ON ..
make osrm-extract-conditionals

The boundaries of the TZ timezones can be downloaded at http://efele.net/maps/tz

wget http://efele.net/maps/tz/world/tz_world.zip
unzip tz_world.zip

Conditional restrictions

Saving conditional restrictions as a CSV file

cond-dump command parses OSM files and prints for all entries that match ^restriction.*:conditional$ key filter information about a conditional restriction in CSV format

from node ID, via node ID, to node ID, restriction key, restriction value, restriction condition, via node longitude, via node latitude

For example

./osrm-extract-conditionals cond-dump germany-latest.osm.pbf  germany-latest-conditional-restrictions.csv
cat germany-latest-conditional-restrictions.csv

Resolve conditions

The CSV file created with the cond-dump command contains conditions in opening hours format. These values can be resolved with the cond-check command for the given UTC time point:

./osrm-extract-conditionals cond-check  germany-latest-conditional-restrictions.csv germany-latest-conditional-restrictions-resolved.csv --tz-shapes world/tz_world --utc 1488194000 --value 16000
