Abstract

One of the key elements of traffic planning is elimination of conflicts, particularly between the nonmotorists and vehicles. The importance of this planning issue was realized by the ancient and medieval planners who separated the pedestrians and vehicles at the street level. Until the late nineteenth and early twentieth centuries, most of the separations were at grade and simple. But with the proliferation of automobiles, separations became complex and diverse. This paper attempts to subdivide different types of separations on the basis of their unique physical and regulatory attributes, and then compares their performance in delivering safety, equity, comfort, and convenience to the different road users (especially to the pedestrians and bicyclists).
