Presentation: Using a Graph Database to Ensure a Routable Road Network

Track: NoSQL / Time: Friday 15:50 - 16:40 / Location: Glazen Zaal

One of the challenges we have at TomTom Maps is to make sure each map update is shippable to customers without lowering the map quality.

One aspect of the quality of our map is making sure the map stays routable. To ensure this for each update we currently rely on Neo4j.

The presentation will go into some detail on the architecture, the size of the graph we maintain, the traversal algorithm and there will also be a short demo.
