Personal data such as video and GPS is collected in many Field Operational Tests (FOT) and Naturalistic Driving Studies (NDS). This data contribute with essential information that e.g. enables an objective view on the driver´s behaviour during different driving scenarios and facilitate map-data enrichment to the collected naturalistic data. The personal data demands though a high level of data protection not to reveal the personal identity outside the group of researcher that has approved access to the data. If the data could be anonymised while still keeping the information that is essential to research, the access and the re-use of the valuable data would be greatly facilitated.
