Description

This video shows three-phase operations featuring a hold-back phase with data characterizing the southbound internal through movement (OL-C) on May 15, 2014, at the SR-201 / Bangerter DDI in Salt Lake City, Utah. The gray dots are associated with vehicles from the upstream ramp movement (OL-H) and the black dots are associated with vehicles from the upstream external through movement (OL-E). Radar detection was used, so closely spaced vehicles often generate one detection for the group instead of a unique detection for each vehicle. Latitude/Longitude: 40.726568° / -111.9855606°
