SPR-3866: Performance of Alternative Diamond Interchange Forms

This research is aimed at developing a set of tables and charts for preliminary comparison of five alternative diamond forms from the point of view of capacity and delays (traffic and geometry-related) and the risk of queue spillback onto a freeway. An additional consideration will be given to the right of way requirements and the impact on safety.
