Buc-ee’s – Efland, NC <br /> <br />23 <br /> <br />6.4 Mt. Willing Road – I-40 EB Ramps <br /> <br />Analyses indicate that the unsignalized Mt. Willing Road – I-40 EB Ramps intersection currently <br />operates with short delays on the minor street approach (I-40 EB Ramp). With the addition of <br />background and site-generated traffic, the minor street approach is expected to continue operating <br />with short delays on the minor street approach in the build-out traffic condition. Note that it is <br />typical for the stop-controlled approach with a major street to experience long delays while the <br />major street experiences little or no delay. Furthermore, in the highest volume peak hour site <br />traffic is expected to account for less than 2% of build-out intersection traffic volumes. No site <br />trips are expected to be added to the eastbound minor-street approach. SimTraffic simulations <br />indicate that maximum queues on the eastbound approach are expected to be less than 100 feet in <br />all peak hours. Note that delays are reported to decrease with the site traffic in the AM Peak <br />Hour. This is due to variations in simulation results and is not uncommon in instances with low- <br />volumes on stop-controlled approaches. <br /> <br />No improvements are recommended at this intersection to accommodate site traffic. <br /> <br />Table 6.4 summarizes the operation of the intersection for the existing (2019) and projected <br />(2022) background and build-out traffic conditions. <br /> <br />Table 6.4 <br />Level-of-Service <br />Mt.
