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. |
