This change takes the existing typedefs for weight, duration and
distance, and makes them proper types, using the existing Alias
functionality.
Primarily this is to prevent bugs where the metrics are switched,
but it also adds additional documentation. For example, it now
makes it clear (despite the naming of variables) that most of the
trip algorithm is running on the duration metric.
I've not made any changes to the casts performed between metrics
and numeric types, they now just more explicit.
This PR improves routing results by adding support for snapping to
multiple ways at input locations.
This means all edges at the snapped location can act as source/target
candidates for routing search, ensuring we always find the best route,
and not the one dependent on the edge selected.
This PR adds more advanced coordinate extraction, analysing the road
to detect offsets due to OSM way modelling.
In addition it improves the handling of bearings. Right now OSM reports
bearings simply based on the very first coordinate along a way.
With this PR, we store the bearings for a turn correctly, making the
bearings for turns correct.
Changes the internal representation of compressed geometries to be a
single array shared between forward and reverse geometries that can be
read in either direction. Includes a change on
extractor::OriginalEdgeData to store via_geometry ids that indicate
which direction to read the geometry for that edge based edge.
Closes#2592
rather than being cached in the StaticRTree. This means we
can freely apply traffic data and not have stale values lying
around. It reduces the size of the RTree on disk, at the expense
of some additional data in RAM.
