Fine nationally used reference books for highway design and traffic operations procedures and three typical state highway manuals were revilement to determine where practice might be afflicted by vehicle characteristics particularly as these characteristics change with successive designs or are performance capabilities that are modified by driver preference. All design and operating characteristics of vehicles that interact with the highway design and traffic operations procedures are listed and discussed. Practically all of the commendations that have been made for reconsideration and review, or establishment of new standards, derive from increased technical knowledge concerning the relationship of the vehicle to the highway and to traffic operations.
