Great writeup on offline OSM routing! If you're also interested in simulating vehicle movement on those road networks — useful for testing tracking or logistics software — Moveet (https://github.com/ivannovazzi/moveet) does exactly that: A* pathfinding on GeoJSON road graphs with WebSocket streaming of real-time positions. It uses the same OSM data you'd be pre-processing here.
