American Express Data Center off Knox Road, Greensboro, Guilford County, NC
DTC was contracted to provide a transportation impact analysis for the proposed American Express Data Center to be located off Knox Road in Guilfford County, NC. This project was also known as "Project Doublewide," a proposed office park. The TIA analyzed two phases of the property's development. Phase 1 consisted of an approximately 198,000 square foot American Express data center facility located on approximately 88 gross acres, with approximately 100 employees. The proposed site connector road (Industrial Street) between Knox Road and Birch Creek Road is intended to be developed during this Phase. This facility is envisioned to be comleted in 2013. Phase 2 development on the approximately 58 gross acres (Tract B) is currently unknown, however, the study assumed a 435,000 square foot general light industrial use for this phase development, with a completion date of 2015. The analysis was conducted based on the scope given by GDOT and NCDOT.
DTC provided level of service (LOS) analysis for for the following eight (8) intersections:
I-40 /I-85 Westbound at Mt. Hope Church Road
- I-40 /I-85 Eastbound at Mt. Hope Church Road
- Mt. Hope Church Road at Knox Road
- Knox Road at Birch Creek Road
- Knox Road at Connector Road
- Birch Creek Road at Connector Road
- Interior access points along proposed Connector Road as indicated on the site plan (two).
DTC provided analysis for the above mentioned intersections for the following scenarios:
- Existing Conditions
- Future No-Build Conditions
- Future Build-Out Conditions
- Future Build-Out with Mitigation as necessary - (Phase 1 - Data Center Only)
- Future Build-Out Conditions - (Full Site Development)
- Future Build-Out with Mitigation as necessary - (Full Site Development)
Analysis was completed for both the AM and PM peaks. Traffic counts were taken when school is in session.
DTC determined the potential traffic impacts of the development and identified transportation improvements that may be required to accommodate the impacts of both backgroupnd traffic and new development traffic for each studied phase. Recommended improvements addressed coordinated signal timing, modification of signal phasing, construction of turn lanes, new roadway/intersection design and construction for Industrial Street, and access management.
