%X Geometric highway design can be evaluated only if the relative merits of the design features can be measured in some fashion. A yardstick is needed that will measure the various design features. Studies have been under way for the past two years to evaluate interchanges by three means- accident records, operation, and capacity. Interchanges can be broken down into three basic elements: (1) the exit terminal, (2) the main portion of the ramp, and (3) the entrance terminal. This paper attempts to show how a variation in the design of these basic elements affects operation and safety.<p />
