Some tools should work on a simplified graph

Currently, the graph is extracted from the OSM data source. A linear road can be split into several small segments if the OSM data requires that (example : to be able to tag some segment to say there are two lanes, wheareas the next one might have a single lane).

It's cumbersome to edit those small segments. As the road network is immutable, could there be a way to pre-process the graph and create a simplified graph that creates only one segment between two intersections? Then, for every tool, there could be a choise to act on the simplified or original graph.

For tools like tagging main roads or changing directions, it could be very helpful.
