摘要

Traffic engineers have long recognized that the elimination of unexpected eventsand the separation of decision points simplifies the driving task. Since access control reduces the number and complexity as well as increases the spacing of events to which the driver must respond, it will result in improved traffic operations and reduced accident experience. Various research efforts are explored and general relationships between accidents and medial and marginal access control is examined.
