I have just started using OSM for hiking tracks. The Directions panel is great for fast planning of tracks, but three times out of eight I have found the route is diverted around what looks like incomplete map data, like connections or permissions. I have edited the data, and would like to check if that fixes the problem, but the effects don't seem to be shown on the directions. I guess this is because OSRM has to wait for a graph update. Could there be a way of checking quicker? Like being able to see the local route graph for a class of transport? Or running the router on what is on screen?

Simon mentioned the JOSM plugins, so I don't understand his categorical "no". I would rather say "yes, but". :-)

Instead of iD you can use the OSM Editor JOSM. For this editor there are two plugins available: GraphView and Routing. Both work with the OSM data currently loaded in the editor including all your changes you have made but not uploaded yet. The former plugin provides an overlay for a routing graph. It's a bit difficult to spot gaps with this tool, though. The latter plugin offers rudimentary routing and enables you to test your edits. It does not take into account access restrictions ("no bicycles here"), though. So it works to test if all roads are there and connected but not to test for the right permissions.

Following up on your advice, I have installed JOSM, found the remote control option, and enabled it. I get Failed to initialize communication with the OSM server http://api.openstreetmap.org/api. Check the server URL in your preferences and your internet connection.

I have also tried downloading a map into JOSM, and get the same message. I have searched for advice on this, followed recommendations about connection and proxy settings , and still get the same. Sorry for all the beginner problems.

@TZorn: as said that was the short version.

@arbuthnot: Better start a new question for this issue.

If you want to test routing for small areas you can use OSMAndMapCreator to generate OsmAnd file that can either be sideloaded onto a phone for testing or tested directly in the map creator software.

The MapCreator software is rather rough, so YMMV on testing without transferring to a mobile device.

I've just checked and the router will route along un-uploaded ways in a JOSM file, so it may be possible to test reasonably complex edits before making them 'live'.

The short answer is: no.

The long version: all routing engines have to update the data and the routing graph in some fashion and currently none of the server side engines does this incrementally (for technical reasons). So typically you will need to wait a day or so to see you changes there.

JOSM used to have a plugin that did this on freshly edited data, but no idea how well this worked/works. Outside of that you best bet is OSMand with a "live" subscription that will typically update in 1-2 hours.
