this is ongoing work on the next version of Itinero, if you want routing right now, please go here

A new temporary repository for v2 routing core, being tile-based.

This is part of the work done by the awesome open planner team.

To consume routable tiles:

More detailed goals are:

• Experiment with tiled-routing.
• Build a fully functioning prototype of what Itinero 2 should be and:
  • Merge this with the current routing core when finished.
  • Or transplant the most valuable concepts over to the current routing core without breaking too much.
• Experiment to see if all the current features of the routing core can be implemented using Itinero 2's new concepts.
  • Island detections is one, how to do this when using multiple tiles?
  • Configurable profiles and changes to profiles?
  • Preprocessing & updating data.

The main thing is to build a tile-based datastructure that replaces (or expands) the current routerdb concept. This should also enable distributed preprocessing of the data. It would be awesome to:

• Live load updates, meaning we can have immidate updates to the routing graph.
• We can add any data to the edges and make this configurable:
  • Distance.
  • Custom costs.
• We can add any data to the vertices and make this configurable:
  • Turn costs.
  • Intersection costs.
  • Meta data.

• Build a basic data structures in tiled form.
  • Get this done for vertices.
  • Get this done for edges.
  • Add support for turn-restrictions.
  • Load tiles on demand.
• Experiment with routing algorithms on top of this.
• Build a proper resolving algorithm and verify performance.
