Roadmap

This is an overview of features that are either in development or on the roadmap:

Version 1.1

This version has been released: https://github.com/itinero/routing/blob/master/docs/releasenotes/itinero-1.1.0.md

This contains some ideas on some non-breaking extensions on top of v1.0.

• Add a weight matrix calculation algorithm that calculates edge->edge weights excluding the source-target edge weights. DONE
  • Check to see if the current edge-based matrix algorithm can be replaced by this more general case. DONE
• And several other issues and ideas: Milestone for 1.1 DONE

Version 1.2

• Meta-data on vertices: More details here.
• A way to extract parts of the network and save them as a new routerDb.
• Use the meta-data on vertices to paste networks back together by keeping node id's.

Version 2.0 and beyond

• Add extension method to directly load data from overpass by polygon.
• Move to netstandard2.0 only.
• Move to .NET core for the functional test project: development should be possible on any platform.
• PLANNED: Constrained routing: Routing with constraints like weight limits or vehicle size (width and height).
• [PLANNED] Destination-only access: Handle access constraints where there is destination only access, also when using contracted graphs.
• Better CH: https://github.com/itinero/routing/issues/92
• Reevaluate Lua profiles: https://github.com/itinero/routing/issues/102
• Figure out a way to better detect islands and route under all conditions: https://github.com/itinero/routing/issues/104
• Support for dynamic weights per edge, for example to handle floating car data: https://github.com/itinero/routing/issues/103
• Look at the filesize of the routerDb's: https://github.com/itinero/routing/issues/105
• Elevation profiles: Output height profiles of calculated routes.
• Elevation-aware routing: Routing that takes into account elevation. Think avoiding steep hills for bicycles.
• No-go areas or maximum speeds based on areas: https://github.com/itinero/routing/issues/19
• Alternative routes.
• Map matching.
• Reevaluate lua for instruction generation of fix performance issues.
• Remove nullable booleans to describe directional information.
• Remove this fix: https://github.com/itinero/routing/issues/108
• cleanup weight handlers, let them die!
• cleanup old way of handling restrictions.
• cleanup using bool? for directions and replace by Dir structure.
• cleanup old way of doing edge-based routing.
• Consider implementing support for multi-level route relations: https://github.com/itinero/routing/wiki/Development-plan:-Handle-multi-level-route-relations.#process-relations-in-multiple-passes
• Move OSM specific parsing to the OSM namespace: IAttributeCollectionExtension

General ideas

A collection of general ideas that may or may not end up on the final roadmap.

Add a more efficient data structure to represent restrictions

Add extension method to turn a routerpoint into GeoJSON

Just return geojson with all details included:

• Edge with start and end vertex.
• The location on the network.
• The original location.
