Sequence and Offset Optimization at a Diamond Interchange

<p>[[Video(youtube.com/watch?v=qi8oOfUFblY)]]</p> <p>Signalized diamond interchanges are unique pairs of intersections characterized by interlocked left turns and relatively close spacing between ramps. A diamond interchange has four external entry points (origins) and four external exit points (destinations). To effectively operate a diamond interchange, it is critical to examine the external origin-destination paths and evaluate their impact on the interior storage and progression.

This video demonstrates the optimized performance at a diamond interchange at I-69 / 96^th^ Street in northeast Indianapolis, IN. The movement observed is the westbound thru movement and depicts an animated time space diagram based on high-resolution event-based data. &#39;&#39;&#39;Latitude/Longitude:&#39;&#39;&#39; 39.927108&deg; / -86.029641&deg;</p>
