While recent research on
intelligent transportation systems including vehicular com-
munication systems has focused on technical
aspects, little research work has been
conducted on drivers’ privacy perceptions and preferences.
Understanding the driver’s privacy perceptions and preferences will allow
researchers to design usable privacy and identity management systems offering
user privacy choices and controls for intelligent transportation systems. We
conducted in-depth semi-structured interviews with 17 Swedish drivers to analyse their privacy perceptions and preferences for
intelligent transportation systems, particularly for user control and for
privacy trade-offs with cost, safety and usability. We also compare our
results from the interviews with Swedish drivers with results from interviews
that we conducted previously with South African drivers. Our cross-cultural
comparison shows that perceived privacy implications, the drivers’ willingness
to share location information under certain conditions with other parties, as
well as their appreciation of Privacy Enhancing Technologies differ
significantly across drivers with different cultural backgrounds. We further
discuss the cultural impact on privacy preferences, including those for
privacy trade-offs, and the implications of our results for privacy-enhancing
Identity Management for future vehicular communication systems. Based on our
findings, we provide recommendations
for privacy settings to be offered to different
users with different cultural backgrounds.
