Abstract—While weaving maneuvers occur on every type of roadway, most studies have focused on freeway maneuvers. Weaving occurring on non-freeway facilities, such as arterial streets, can cause significant operational and safety problems. Arterials, unlike freeways, tend to have shorter weaving lengths and lower speeds. Intensive lane changing maneuvers at weaving sections create turbulence that often leads to congestion. The Right Turn Split (RTS) design is a new design to relieve congestion and delay caused by weaving movements on arterial streets. The RTS design facilitates smoother flows with less driver delay. Pilot studies were conducted at two arterial weaving sections in Florida to demonstrate the feasibility of the approach. The intent of this paper was to study the impacts of the RTS installation based on a before-and-after study of the delay on an arterial street. To conduct the before-and-after study, the delay before and after was compared for multiple volume conditions using microscopic simulation analysis to determine how the delay of the arterial segment would differ over a wide range of volume levels.
