## What-if analysis ## What-if analysis
This allows you to make changes to the street network (add a bike path, reduce a lane on an arterial st) and see how it affects the routes that brouter chooses.

This is currently not working, I'm trying to figure it out.
This is a multi-step process: This is a multi-step process:
1. Make edits to OpenStreetMap in [JOSM](https://josm.openstreetmap.de/) 1. Generate an OsmChange file for the changes that you want to analyze. Don't upload your hypothetical infrastructure to OpenStreetMap!
2. Save the edited map as `docker/brouter/osm_edit/map_edited.osm` (File -> Save As). Don't upload your hypothetical infrastructure to OpenStreetMap! 2. Save that file as `docker/brouter/osm_edit/changes.osc`.
3. `make osm_edit_refresh_base` will download a fresh copy of `wisconsin-latest.osm.pbf` and the elevation tiles for Wisconsin. You don't need to run this frequently. 3. `make osm_edit_refresh_base` will download a fresh copy of `wisconsin-latest.osm.pbf` and the elevation tiles for Wisconsin. You don't need to run this frequently.
4. `make osm_edit_generate_pbf` will take those edits and apply them to the `wisconsin-latest.osm.pbf` and generate `wisconsin-latest_edited.osm.pbf` 4. `make osm_edit_generate_pbf` will take those edits and apply them to the `wisconsin-latest.osm.pbf` and generate `wisconsin-latest_edited.osm.pbf`
5. `make osm_edit_generate_brouter` will generate new brouter segment files from the edited pbf file. 5. `make osm_edit_generate_brouter` will generate new brouter segment files from the edited pbf file.
