That is,the eastbound approach of the Old NC 86 at 1-40 eastbound ramp operates at <br /> LOS E in the PM peak hour. The level of service and delay for the existing traffic conditions is listed below in Table 4. <br /> Table 4: Level of Service and Delay for 2020 Existing Conditions <br /> Existing 2020 Existing <br /> Intersection Approach Intersection AM Peak PM Peak <br /> Control <br /> LOS LOS <br /> (Delay in sec./veh.)
