Enterprises, infrastructure, vehicle stock

Enterprises engaged in transport activities on inland waterways, by air and rail as well as in commercial passenger transport and goods transport by road are required to provide information every year or at intervals of several years. They supply data in particular on the transport services performed, the employees involved in transport activities, on turnover or revenue from the relevant mode of transport (except for goods transport by road and rail and long-distance passenger transport by rail), on the stock of vehicles and on the infrastructure (railways). The survey units are the kind-of-activity units engaged in transport activities, irrespectively of what the enterprise's main activity is. The surveys are usually conducted on an exhaustive basis (except in road goods transport) and thus provide results of high accuracy.

The register-based transport statistics must be seen in the light of functional objectives, especially the road motor vehicle statistics compiled by the Federal Motor Transport Authority (KBA). In other areas, too, evaluations of administrative registers serve to complement survey data, especially those on the infrastructure and means of transport. This applies, for instance, to information on the stock of inland waterway vessels, sea-going vessels, aircraft, and on other than local roads.
