End use cases are the same as public transport : automatize this kind of chart production, feed simulators, routing software... https://www.sifoee.com/static/images/score.png "Build it and they will come" is a bit necessarily since taking data from GIS isn't a so common thing currently. BI and asset management are still often separated from GIS This has to change and osm can bring useful tools for that. All the best François
