GEOMETRIC DESIGN AND SIGNALIZATION CHARACTERISTICS OF DIAMOND INTERCHANGES

The state-or-the-art of diamond interchange control and design techniques was examined to determine the amount of variation that can be expected for the various factor levels of diamond intercharge characteristics. Several agencies throughout the country were contacted, and they contributed a large, representative amount of data for a substantial number of interchange sites. The three major types of information analyzed were geometrics, signalization, and demands. A large number of findings are documented, which include statistics on interramp distances, distances to the nearby signalized intersection, number of lanes, number of turning options, lengths of turning packets, signal control types, number of dials, types of phasing sequences, and demand distributions.
