Forschungsdatenzentrum im Kraftfahrt-Bundesamt (FDZ im KBA)

The Kraftfahrt-Bundesamt (KBA), Germany’s Federal Motor Transport Authority, is within the scope of the Bundesministerium für Verkehr und digitale Infrastruktur (BMVI), Federal Ministry of Transport and Digital Infrastructure. The KBA makes an important contribution towards road safety, environmental protection, and the provision of information on road traffic. Initiated and financed by the BMVI, the development of the research data centre Forschungsdatenzentrum im Kraftfahrt-Bundesamt (FDZ im KBA) started in 2017. The aim of the FDZ im KBA is to provide access to anonymised microdata for scientific research purposes.

The data offered by the FDZ im KBA includes at the moment information about additions to the Register of Driver Fitness (Fahreignungsregister) which records the following decisions:

  • Legally binding decisions concerning criminal or administrative offences if they are listed in Annex 13 to Section 40 Fahrerlaubnis-Verordnung (FeV)
  • Decisions made by the driving licence authorities concerning the withdrawal, refusal or newly grant of driving licences
  • Decisions concerning measures provided for by the Fahreignungs-Bewertungssystem, the Driver Fitness Assessment System

Additions to the Register of Driver Fitness (Fahreignungsregister) are provided on an annual basis. In addition to providing documentation of data in German language, the FDZ provides user support on issues such as analytical potential and access to data. The FDZ im KBA provides various modes of data access. An anonymised Scientific Use File is available for off-site access. More detailed analyses requiring a lesser degree of anonymisation can be performed on-site as a guest researcher.
