124 <br /> RESEARCH TRIANGLE LOGISTICS PARK TRAFFIC IMPACT ANALYSIS <br /> Executive Summary <br /> The Research Triangle Logistics Park is a proposed development located along Old NC 86 in Hillsborough, Orange <br /> County, NC. The site encompasses the area along the west side of Old NC 86, between Davis Road and Interstate <br /> 40(1-40)and is anticipated to be completed in 2023.The site is envisioned to consist of 2,251,200 square feet of <br /> warehouse. <br /> At build out, the proposed development is anticipated to generate 3,648 new trips per average weekday. In the AM <br /> and PM peak hours, the development will generate approximately 320 AM peak hour trips(247 entering and 73 <br /> exiting)and 326 PM peak hour trips(88 entering and 238 exiting). <br /> Access to the proposed development is expected to be provided by the existing Service Road; which parallels 1-40, <br /> and Davis Road. There are three (3)proposed driveways along the Service Road and one driveway proposed for <br /> Davis Road. <br /> The purpose of this report is to evaluate the development in terms of projected vehicular traffic conditions, evaluate <br /> the ability of the adjacent roadways and multimodal facilities to accommodate the additional traffic and to recommend <br /> transportation improvements needed to mitigate congestion that may result from additional site traffic. This report <br /> presents trip generation, trip distribution,traffic analyses, and recommendations for improvements needed to meet <br /> anticipated traffic demands.This report examines the following scenarios for the AM and PM peak hours: <br /> • 2020 Existing <br /> • 2023 No-Build <br /> • 2023 Build <br /> • 2023 Build-Improved <br /> Capacity analyses for the AM and PM peak hours in each scenario were performed for the following existing <br /> intersections: <br /> • Old NC 86 at Waterstone Drive/Rippy Lane; <br /> • Old NC 86 at 1-40 Westbound Ramp; <br /> • Old NC 86 at 1-40 Eastbound Ramp; <br /> • Old NC 86 at Service Road; and <br /> • Old NC 86 at Davis Road. <br /> Table ES-1 shows a summary of the delays and levels of service for the study area intersections. The following are <br /> observations resulting from the traffic analysis. <br /> Heavy left-turning traffic is noted on the southbound approach to the intersection of Old NC 86 at the 1-40 Eastbound <br /> Ramp. The proposed development does not add vehicles to this turn. The analysis of this proposed signal is <br /> performed conservatively using protected-only left-turn treatments per North Carolina Department of Transportation <br /> Congestion Management Capacity Analysis Guidelines. It is likely that this left-turn will be designed and operated <br /> with a flashing yellow arrow;which would improve operations. <br /> Queues were observed to extend along Old NC 86 from the 1-40 Eastbound ramps beyond the Service Road. This <br /> impediment creates longer queues on the Service Road. As discussed previously,operating the southbound left-turn <br />
