Microsimulation shows targeted lane changes would limit delays if ‘The Avenue’ proceeds; council wary of blocking Tenth Street through-movement
Summary
An independent VISSIM microsimulation of U.S. 41 traffic found adding a westbound left at the 4 Corners intersection plus dual northbound right-turn lanes at Tenth Street (Option 1) produces the largest reduction in modeled afternoon delays, but several councilors opposed restricting the Tenth Street through movement and asked staff to pursue Option 2 first.
A consultant-conducted traffic microsimulation of the U.S. 41 corridor around Ninth–Tenth Streets found targeted geometric changes could reduce key travel-time delays from a proposed mixed-use development called the Avenue (formerly the M development), but city councilors raised concerns about access for south-side neighborhoods if the northbound-through movement at Tenth Street were restricted.
What was presented: Independent consultant Ricky Matthews summarized a VISSIM microsimulation of current traffic, the no-build scenario (project traffic added but no roadway changes), and two mitigation options. Option 1 combined a new westbound left turn lane at the 4 Corners intersection with converting a northbound through/right lane at Tenth into two right-turn lanes (dual-rights). Option 2 included only the additional westbound left lane without changing the Tenth Street northbound movement.
Key technical findings: Matthews said Option 1 produced the best system-wide…
