Dynamic Lane Grouping At Signalized Intersections: Selecting The Candidates And Evaluating Performance

Abstract

Dynamic lane grouping (DLG) aims to adjust lane assignment based on fluctuating travel demand to further improve traffic operational efficiency at signalized intersections. A tool is developed to automatically and efficiently identify intersections likely to benefit from DLG treatment. The benefits resulting from DLG are demonstrated by a case study. DLG offers one way to narrow the gap between supply and demand. The first step of DLG is identifying the candidate intersections. One example of real-world DLG implementation is the intersection of Shady Grove and US 355 in Maryland, where eastbound right-turn demand nearly doubles in the weekday AM peak as compared to other times of day.
