Priority treatments for high-occupancy vehicles (HOV) can introduce new safety problems due to operational or geometric modifications. At the same time, they can reduce the accident potential by improving overall traffic operations. The research focused on five major areas of HOV projects: (1) an examination of the pertinent accident rates, (2) an analysis of causative factors influencing safety, (3) an identification of difficult manoeuvres and potential safety problems. (4) the development of recommendations to improve safety, and (5) a review of the legal authority and legal liability issues faced by HOV projects.
