摘要：AbstractThe goal of this project is to develop a structured and objective evaluation process to compare alternative design concepts and evaluate them based on operations, safety, access management, and pedestrian/bicycle accommodations. This approach permits a more objective comparison of all alternatives, since all options target the same operational service level. The Intersection Design Alternative Tool (IDAT) developed through this effort is capable of evaluating 13 different intersection alternatives and it would be invaluable in evaluating alternative designs that could enhance access management and implementing innovative intersection treatments such as alternative left-turn treatments.
