If you enable the `-DDEBUG_GEOMETRY` flag with `make`, then `osrm-extract` and `osrm-prepare` can be instructed (with a new command-line parameter) to dump out some geometry information in GeoJSON format. `osrm-extract` will dump out turn and stop-sign penalties with coordinates and bearings. `osrm-prepare` will dump out individual segment weights (deciseconds) and speed values used in the final routing graph. It's not super-easy to use, but it gives complete insight into the routing graph in a visual form. You can load the files into QGIS for visualization. daniel On Nov 11, 2015, at 4:32 PM, Sotorrio, Pedro <sotorr...@llnl.gov<mailto:sotorr...@llnl.gov>> wrote: Thanks a lot, Daniel! —Pedro From: Daniel Hofmann <hofm...@mapbox.com<mailto:hofm...@mapbox.com>> Reply-To: Mailing list to discuss Project OSRM <osrm-talk@openstreetmap.org<mailto:osrm-talk@openstreetmap.org>> Date: Wednesday, November 11, 2015 at 1:26 PM To: Mailing list to discuss Project OSRM <osrm-talk@openstreetmap.org<mailto:osrm-talk@openstreetmap.org>> Subject: Re: [OSRM-talk] Extended graph output file The edge-expanded graph already gets written to disk; this was introduced in the following commit: https://github.com/Project-OSRM/osrm-backend/commit/e45656e5bfb0b61a2859f0c754e66322996f1640 which is not yet in the latest release, so you have to build from the develop branch. If you search for ebg you will see related files: https://github.com/Project-OSRM/osrm-backend/search?utf8=%E2%9C%93&q=ebg Word of caution: the serialization in OSRM is done by just dumping internal datastructures in binary format. This is neither a portable between operating systems, compilers or even standard libraries, nor a stable format, and in particular not intended to be read from other programs. You would have to get the data structure layout right, in order to make use of the ebg file from other programs.

Is there a way to write out the edged expanded graph (with turns) to a readable file?
