• Abstract:
  This report investigates technical approaches to address privacy concerns associated with two innovative ; applications enabled by connected vehicle systems, i.e., origin-destination (OD) flow measurement and differentiated ; congestion pricing. The former is to retrieve the OD information from connected vehicles while ; the latter charges congestion tolls with respect to travel characteristics of connected vehicles, e.g., origins, ; destinations or paths that they traverse between their origins and destinations. Since both applications require ; tracking vehicles, they may violate the “anonymity by design” principle adopted by connected vehicle ; systems. For OD flow measurement, a novel measurement scheme is developed to collect aggregate OD ; flow data without compromising motorists’ privacy. For differentiated congestion pricing, an incentive program ; is designed to encourage motorists to voluntarily reveal their private information and create a win-win ; situation for both motorists and the society.
