Do openStreetMap have traffic limitation and is a routable map? Can I convert openStreetMap into our navigation map, used in navigtion device. Thanks.
Hello Vivienne,
Actually, OpenStreetMap (OSM) is just a database of geographic information which is suitable for a whole range of applications. Routing is certainly one of those. There are many options to describe road features related to routing (turn restrictions, traffic calming, oneways, access rules), all of them can be mapped in OSM althought the level of detail may vary. Have a look at the wiki page about routing and OSM for some more information.
