May 13 th, 2014 Portage County, Ohio Tallmadge Road Corridor and Interchange Improvement Project

SAFETY STUDY PRESENTATION PROJECT LOCATION & DESCRIPTION Tallmadge Road Corridor Parliament Drive to Sunnybrook Road Distance – 1.1 Miles Approximate ADT – Opening Year 2019 – 15,940 Certified Traffic Obtained & Used for Analysis (Certified at 0% Per Year Growth)

POR – Tallmadge Road Corridor Study Area SAFETY STUDY PRESENTATION

REGIONAL PRIORITY The Congestion Management Process Study published by AMATS in July 2012 lists Congestion Reduction Strategies for various intersections. Listed below is the strategy for the study corridor: I-76 / Tallmadge Road / Mogadore Road Interchange – Reconfigure Interchange. This is the highest crash corridor in Portage County (80 Crashes). Next Closest area is the State Route 59 corridor near the State Route 261 intersection (68 crashes). SAFETY STUDY PRESENTATION

CRASH ANALYSIS SUMMARY 80 Crashes Reported in Study Area from 2010 – Rear-end 10 Angle 8 Left Turn 7 Sideswipe - Passing 5 Fixed Object 4 Other Non-Collision 3 Sideswipe – Meeting *Note the High Number of Rear-End Crashes

SAFETY STUDY PRESENTATION CRASH ANALYSIS Much Higher than Average Rear-End Crashes Inefficient Cluster Signal Operation at I-76 WB Exit Ramp / Mogadore Road / Tallmadge Road Intersection Non-Traditional Interchange Geometrics at I-76 / Tallmadge Road Interchange Conclusion – Congestion Related Crashes Resulting from Inefficient Operations in Study Area

SAFETY STUDY PRESENTATION PROPOSED COUNTERMEASURES Eliminate both Mogadore Road junctions with the I-76 Exit Ramps to Remove the Mogadore Road / Ramp Overlap Sections Relocate / Reconstruction Mogadore Road (West) to tie into Existing East End Welding Cul-de-Sac Mogadore Road (East) and Reroute all Traffic to Sunnybrook Drive Reconstruct the Traffic Signal at the Reconfiguration Intersection of Tallmadge Road / I-76 WB Ramps. Construct a Traffic Signal at the Newly Created Intersection of Tallmadge Road / Mogadore Road Convert the I-76 / Tallmadge Road Interchange from a Tradition Diamond Interchange Into a Diverging Diamond Interchange Interconnect the Traffic Signals Along the Tallmadge Road Corridor to Form a Coordinated Signal System
