Buc-ee’s Phase 2 – Efland, NC <br /> <br />29 <br /> <br />The I-40 EB Service Road segment was analyzed as a one-sided collector-distributor weave. <br />Vehicles exiting eastbound I-40 via Exit 161 to make a turn onto US-70/I-40 Connector must <br />make one lane change in the same segment where vehicles exiting Mt. Willing Road must make <br />one lane change to merge onto I-40 EB. A free-flow speed of 50 mph and a weaving length of <br />705 feet were assumed for the mainline segment. A free-flow speed of 45 mph was assumed for <br />the I-40 EB ramps. <br /> <br />The I-40 WB Service Road segment was also analyzed as a one-sided collector-distributor weave. <br />Vehicles exiting the East RIRO Site Drive must make one lane change to merge onto I-40 WB. A <br />free-flow speed of 50 mph and a weaving length of 1075 feet were assumed for the mainline <br />segment. A free-flow speed of 45 mph was assumed for the I-40 EB ramps. Note that the <br />proposed removal of the existing I-40 WB Exit 160 off-ramp eliminates the existing weave made <br />by traffic exiting Exit 160 and turning onto Mt. Willing Road. <br /> <br />A 0.90 peak hour factor and a 2.0% heavy vehicle percentage were used for all scenarios. Ramp <br />distances and grades were measured using Orange County GIS data. <br /> <br />The peak hour weaving LOS for the projected (2023) build-out condition is shown in Table 7.1. <br /> <br />Table 7.1 <br />Weaving Level-of-Service Summary <br />Condition AM Peak Hour <br />LOS (Delay) <br />PM Peak Hour <br />LOS (Delay) <br />I-40 EB Service Road (Mt. Willing Road to US-70/I-40 Connector) <br />Build (2023) Traffic C (24.1) <br />v/c = 0.83 <br />B (14.9) <br />v/c = 0.52 <br />I-40 WB Service Road (East RI/RO Site Driveway to Mt. Willing Road) <br />Build (2023) Traffic A (10.6) <br />v/c = 0.30 <br />B (21.6) <br />v/c = 0.63 <br /> <br /> <br />As shown in Table 7.1, both I-40 service road segments operate with an acceptable weaving LOS <br />and v/c ratio in the projected build-out traffic condition. <br /> <br /> <br /> <br /> <br />475
