The internal representation of turn restrictions expects only one
`from` way and only one `to` way.
`no_entry` and `no_exit` turn restrictions can have multiple `from` and
`to` ways respectively. This means they are not fully supported by
OSRM's restriction parser.
We complete support for these turn restriction types by parsing all
ways and converting a valid restriction with multiple `from`/`to` members
into multiple internal restrictions.
Currently OSRM only supports turn restrictions with a single via-node or one
via-way. OSM allows for multiple via-ways to represent longer and more
complex restrictions.
This PR extends the use of duplicate nodes for representng via-way turn
restrictions to also support multi via-way restrictions. Effectively, this
increases the edge-based graph size by the number of edges in multi via-way
restrictions. However, given the low number of these restrictions it
has little effect on total graph size.
In addition, we add a new step in the extraction phase that constructs
a restriction graph to support more complex relationships between restrictions,
such as nested restrictions and overlapping restrictions.
Makes turn restrictions into dedicated structures and diferentiates between them via a variant.
Ensures that we do not accidentally mess up ID types within our application.
In addition this improves the restriction performance by only parsing all edges
once at the cost of (at the time of writing) 22MB in terms of main memory usage.
* optionally include condition and via node coords in InputRestrictionContainer
* only write conditionals to disk, custom serialization for restrictions
* conditional turn lookup, reuse timezone validation from
extract-conditionals
* adapt updater to use coordinates/osm ids, remove internal to external map
* add utc time now parameter to contraction
* only compile timezone code where libshp is found, adapt test running
* slight refactor, more tests
* catch invalid via nodes in restriction parsing, set default cucumber
origin to guinée
* add another run to test mld routed paths
* cosmetic review changes
* Simplify Timezoner for windows build
* Split declaration and parsing parts for opening hours
* adjust conditional tests to run without shapefiles
* always include parse conditionals option
* Adjust travis timeout
* Added dummy TZ shapefile with test timezone polygons
* [skip ci] update changelog
Takes a stricter aproach for whitelisting / blacklisting restrictions:
- uses `restriction=`
- uses more specific `restriction:<type>=`
- uses `except=<type>` to invert
Where `type` is the type of transportation to restrict, e.g. `motorcar`.
