Traffic operations reports signal timing adjustments on Army Trail and Dunham to ease backups
Summary
Traffic staff reported recent signal timing changes near Army Trail and Dunham in the St. Charles/Wayne area to reduce long backups on Dunham; staff said adjustments balance mainline flow with side-street service and that some trade-offs are unavoidable.
Traffic operations staff reported the department has fielded public comments about longer backups on Dunham Road and described recent signal timing adjustments near Army Trail in the St. Charles/Wayne area to reduce the queues.

Traffic staff noted there are trade-offs and certain physical and signal limitations that constrain how much delay can be reduced on all approaches simultaneously. Committee members had no further questions on the item after staff summarized the outcome.
Staff invited members to read the packet for details on signal timing methodology and local observations; no vote or formal action was required for this informational item.
