Study Goals Analyze traffic operations along the corridor and at the two study interchanges Provide safety enhancements Improve multimodal performance and better accommodate pedestrians Minimize potential construction costs

Study Area Our study area is the section of NC 54/US 15-501 between Raleigh Rd and South Columbia/NC 86 Separated into 2 sections based on available traffic count data Section 1: Raleigh Rd interchange and adjacent intersections on NC 54/US 15-501 Section 2: NC 86 interchange and adjacent NC 86/Mt Carmel Church Rd intersection

Study Area

Preliminary Assumptions – Raleigh Rd Study Scenarios: Existing Year (2016) No-Build Future Year (2030) Build Peak Hours: Weekday AM Weekday PM Annual growth rate of 1%

Design Concept – Raleigh Rd

Preliminary Results & Observations – Raleigh Rd Two proposed signals on Raleigh Rd and one on NC 54/US 15-501 south of Raleigh Rd all intersecting with ramps Proposed signals are operating at LOS C or better during weekday peak hours Improves safety at interchange by eliminating weave segments on Raleigh Rd Better accommodates pedestrians by providing crosswalks/ped phasing at signals on Raleigh Rd Old Mason Farm Rd/Carmichael Ct intersection is operating at LOS E during the AM peak and LOS F during the PM

Preliminary Assumptions – NC 86 Study Scenarios: Existing Year (2014) No-Build Future Year (2040) Build Peak Hours: Weekday AM Weekday PM Utilizing volumes from US 15-501 Widening – Project Level Traffic Forecast (U-5304)

Design Concept – NC 86 Evaluating grade separated intersection idea that was developed by Dr. Hummer
