This Technical Report gives general guidelines to developers of intelligent transport systems (ITS) and its standards on data privacy aspects and associated legislative requirements. It is based on the EU-Directives valid at the end of 2013. It is expected that planned future enhancements of the Directives and the proposed General Data Protection Regulation including the Report of the EU-Parliament of 2013-11-22 (P7_A(2013)0402) will not change the guide significantly.
