In this paper, we consider an important problem of privacy-preserving point-to-point traffic volume measurement in vehicular cyber physical systems (VCPS), whose focus is utilizing VCPS to enable automatic traffic data collection, and measuring point-to-point traffic volume while preserving the location privacy of all participating vehicles. The novel scheme that we propose tackles the efficiency, privacy, and accuracy problems encountered by previous solutions. Its applicability is
