Eastbound Iowa Street – How the Queue Cutter Traffic Signals Work

This video animation gives a focused view of how traffic traveling eastbound on Iowa Street interacts with an active rail crossing and the roundabout. Special traffic signals at the railroad crossing, called Queue Cutters, hold and release traffic in intervals after a train has just passed. This allows traffic at the roundabout to move more smoothly and increases safety at the railroad crossing for motorists, so vehicles don’t block the railroad tracks.
