From a pool of possible traffic applications, groups will be defined. First, systems with a lot of users and a lot of money transfer, and systems with a lot of users, ecological issues, and data protection critical issues are selected. Second, applications with special technologies in case of improvement of comfort or security will be analysed. Analysing these applications, the dissemination, improvement and visualisation in polychromic media by third parties will be a central view. More or less these studies will different horizontal (closed systems) and vertical application (in a chain disseminated data). Finally, also other factors will be analysed, which are important for mobility services. In a conclusion inconsistencies and additions of the different law areas will be shown and recommendations for further use (maybe a change of national law or including in national framework plans).
