84 CHAPTER 9: CONCLUSIONS AND RECOMMENDATIONS This section documents the key conclusions from the research, a plan for implementing the research, and recommendations for future research. KEY CONCLUSIONS • ATLs are applied at signalized intersections throughout the United States as a congestion-relief treatment to mitigate bottlenecks along arterials.

85 data only when highly aggregated, but a validated SSAM model for use at ATLs could potentially be made available to designers if there was enough collision data to constitute a large sample size. • The results from a safety analysis found a relatively infrequent occurrence of rear end and sideswipe collisions at each of the sixteen analyzed approaches.

86 • Present conference and journal papers at TRB and ITE conferences on the following topics : High level guidelines approach Operations Method (deterministic and simulation approach) Safety Method Design Method RECOMMENDATIONS FOR FUTURE RESEARCH This research effort is the first of its kind to provide practitioners with methods and procedures to assist in assessing the need for, and the evaluation and design of ATLs.

87 o Reduction of the green time on ATL approaches to encourage more traffic to use the ATL in order to avoid waiting multiple cycles. This can be done by reallocating green time to other movements at the intersection • Incorporate the ATL lane use prediction method into the next update of the Highway Capacity Manual and embed the analytical routines within the computational engine for the signalized intersection chapter.
