Weight and duration penalties are flipped in the lambda function
that applies penalties from traffic signals.
Duration is in deciseconds, whilst weight is multipled by
10^weight_precision, with weight_precision being 1 by default.
Therefore, for default routability profile, the penalties end up
being the same, hence why no tests picked this up.
If distance weight is used however, it will incorrectly apply an
additional penalty to the weight, and not add the traffic signal
delay to the duration in the routing graph.
To confuse things further, in some API responses the values are
correct because they use geometry data instead, but it's still
possible that a sub-optimal route was selected.
However, given the distance weight is in meters, and the additional
penalty per traffic light would be 20, it's unlikely this would
have changed the routing results.
In any case, we correct the function to apply the arguments correctly.
Currently OSRM parses traffic signal nodes without consideration
for the direction in which the signal applies. This can lead
to duplicated routing penalties, especially when a forward and backward
signal are in close proximity on a way.
This commit adds support for directed signals to the extraction and
graph creation. Signal penalties are only applied in the direction
specified by the OSM tag.
We add the assignment of traffic directions to the lua scripts,
maintaining backwards compatibility with the existing boolean
traffic states.
As part of the changes to the internal structures used for tracking
traffic signals during extraction, we stop serialising/deserialising
signals to the `.osrm` file. The traffic signals are only used by
`osrm-extract` so whilst this is a data format change, it will not
break any existing user processes.
Currently there is an edge-case in the turn restriction implementation,
such that routes can not be found if the target input location snaps
to a way used in a (multi) via restriction.
With the addition of snapping input locations to multiple ways, we
can now also snap to the "duplicate" edges created for the restriction graph,
thereby fixing the problem.
This is achieved by adding the duplicate restriction edges to the
geospatial search RTree.
This does open up the possibility of multiple paths representing exactly
the same route - one using the original edge as a source, the other
using the duplicate restriction graph edge as source. This is fine,
as both edges are represented by the same geometry, so will generate
the same result.
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.
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.
OSM data contains many mistakes that tag kerbs as highway barriers
when instead they are only describing highway crossings.
This PR updates the default car profile to handle these mistakes
and unblock routing on the affected highways.
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.
* In Belgium the maximum speed in rural areas is 70 in the region Flanders
* parse maxspeed using source:maxspeed and maxspeed:type tags
* add changelog
* make maxspeed:advisory more important than maxspeed
* add test for source:maxspeed
Includes all edges in the rtree, but adds an `is_startpoint` flag to each. Most plugin behaviour remains unchanged (non-startpoint edges aren't used as snapping candidates), but for map matching, we allow snapping to any edge. This fixes map-matching across previously non-is_startpoint edges, like ferries, private service roads, and a few others.

- refactor conditional restriction handling to not use external data (first OSM nodes on ways)
- BREAKING: changes internal file format of osrm.restrictions
- add support for general conditional penalties based on edge-based nodes (requires unique edges between nodes)
