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. In many real-world cases, significant variations in traffic demand are difficult to fully accommodate through signal timing optimization alone. The first step of DLG is identifying the candidate intersections. However, analyzing hundreds of intersections through engineering judgment is not cost-effective. An automatic screening tool is needed for agencies to quickly identify DLG candidates within a huge number of intersections. The tool described in this paper implemented four criteria that evaluate traffic supply and demand from different perspectives. At arterial intersections the traffic demand may vary significantly by time, and the lane assignments, designed for severe peak-hour traffic, might not suit these different demand patterns.
