Review of Discussion from Mtg #5
4
•Three Themes/Objectives of Study
•Safety
•Reduce Congestion/Maintain Access
•Reduce Cut-Through
•Difficulty of balancing tradeoffs
•Strategies to address one objective often result in negative impacts to another
• i.e. mitigation to reduce congestion can lead to more cut-through, and visa versa
•All four neighborhood groups ranked Reducing Cut-Through as #1 priority

PM Peak Turn Restriction Impacts - Change in Delay
Only significant changes in delay (generally more than 10 seconds) are shown.
-10 sec-32 sec

Turn Restriction Impacts• Fewer southbound vehicles turning from West Taylor Run onto
Telegraph Road leads to improvement in overall signal operation
• Less green time needed for SB West Taylor Run
• Four (4) seconds of green time shifted from West Taylor Run to
Duke Street
• Additional vehicle volumes turning left onto West Taylor Run
from Janneys Ln would make it more difficult for northbound
vehicles on West Taylor Run to exit the street onto Janneys Lane
• Fewer vehicles entering Clover-College Park on Trinity Drive
would result in decreased delay on Duke Street at both Yale
Drive and Cambridge Street intersections
• Analysis did not result in any significant impacts on N Quaker Ln
and Duke St signal

Evaluate Turn Restriction Impacts in 6-12 Months
• Drivers have many routing options through the Study area, so it
is difficult to fully predict and analyze every possible scenario
• If implemented as Pilot project, Staff will collect additional data
and evaluate impacts of turn restrictions in 6-12 months
