1. 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

2. Study Area
Our study area is the section of NC 54/US 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
Section 2: NC 86 interchange and adjacent NC 86/Mt Carmel Church Rd intersection

3. Study Area

4. 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%

5. Design Concept – Raleigh Rd

6. Preliminary Results & Observations – Raleigh Rd
Two proposed signals on Raleigh Rd and one on NC 54/US 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

7. 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 Widening – Project Level Traffic Forecast (U-5304)

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