Information about
Open Transport Map (OTM; www.opentransportmap.info) allows routing and visualization of traffic volumes of the whole European Union. The underlying data come from OpenStreetMap and are accessible in a scheme compatible with INSPIRE Transport Network. Open Transport Map can serve as a map itself as well as a layer embedded in your map. OTM is accessible via both GUI and API. Experimental version of OSM is published as Linked Open Data and available through the SPARQL endpoint. OTM is implemented in cultural tourism by many various ways: background data showing traffic infrastructure, input data for analysis or data about traffic volumes, which are essential in cases overcrowded parts of cities or areas struck by air pollution.
