• Description:
  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.
