RESEARCH TRIANGLE LOGISTICS PARK TRAFFIC IMPACT ANALYSIS <br />Capacity Analysis <br />June 4, 2020 <br /> 25 <br /> <br />6.1 2020 EXISTING CAPACITY ANALYSIS <br />The 2020 Existing scenario results show that all intersections currently operate at LOS D or better in both peak <br />periods with one exception. That is, the eastbound approach of the Old NC 86 at I-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 />Intersection Approach <br />Existing <br />Intersection <br />Control <br />2020 Existing <br />AM Peak <br />LOS <br />(Delay in sec./veh.) <br />PM Peak <br />LOS <br />(Delay in sec./veh.) <br />Old NC 86 at <br />Waterstone Drive / <br />Rippy Lane <br />Overall Intersection <br />Signalized <br />B (16.4) B (16.4) <br />EB Approach D (43.4) D (43.4) <br />WB Approach C (26.1) C (31.7) <br />NB Approach B (10.4) B (11.3) <br />SB Approach B (17.9) B (13.5) <br />Old NC 86 at <br />I-40 WB Ramps <br />Overall Intersection <br />One-Way <br />Stop <br />Controlled <br />A (1.0) A (1.6) <br />WB Approach C (21.9) C (22.0) <br />NB Left-Turn A (9.9) A (9.9) <br />SB Approach A (0.0) A (0.0) <br />Old NC 86 at <br />I-40 EB Ramps <br />Overall Intersection <br />One-Way <br />Stop <br />Controlled <br />F (51.2) A (7.0) <br />EB Approach F (###) F (54.6) <br />NB Approach A (0.0) A (0.0) <br />SB Left-Turn B (12.1) A (9.8) <br />Old NC 86 at <br />Service Road <br />Overall Intersection One-Way <br />Stop <br />Controlled <br />A (0.2) A (0.2) <br />EB Approach B (13.1) B (13.5) <br />NB Left-Turn A (8.0) A (8.2) <br />Old NC 86 at <br />Davis Road <br />Overall Intersection <br />One-Way <br />Stop <br />Controlled <br />A (4.8) A (2.3) <br />EB Approach C (21.1) C (17.2) <br />NB Left-Turn A (8.0) A (8.3) <br />SB Approach A (0.0) A (0.0) <br />###: Delay exceeds 300 seconds / vehicle <br /> <br />148
