Diverging diamond interchanges (DDI) are a relatively recent adaptation of signalized interchanges. This video shows several cycles of a diverging diamond interchange at SR-201 / Bangerter in Salt Lake City, Utah on December 18, 2013. The video observes southbound traffic and how the vehicles arrive at the downstream stop bar. The upper plot is a Flow Profile Diagram and the lower graph is a Purdue Coordination Diagram (PCD). Both are used to assess arrival on green performance. '''Latitude/Longitude:''' 40.725819° / -111.986311°
