T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationEffects on Peak Hour Traffic Flow (Level of Service) – 2020/2025This section documents the effects of Alternative B4 on morning and evening peak hour traffic flow.Nine locations would improve under Alternative B4 when compared with the No-Action Alternative:• Post Road (U.S. Route 1) at Lincoln Avenue – During the morning peak hour in 2020 and 2025, overallintersection operations would improve from LOS C under the No-Action Alternative to LOS B underAlternative B4 as a result of minor signal timing and phasing adjustments.• Post Road (U.S. Route 1) at Partially Relocated Airport Road and Ann & Hope driveway – In both 2020 and2025, morning peak hour operations would improve from LOS D under the No-Action Alternative to LOS Cunder Alternative B4. The relocated intersection would be designed to accommodate all movements at theintersection, including the relocated Ann & Hope driveway.• Airport Road at Commerce Drive – In 2025, morning peak hour operations would improve from LOS Dunder the No-Action Alternative to LOS C under Alternative B4 as a result of minor signal timing andphasing adjustments.• Airport Road at Warwick Avenue – During the morning peak hour in 2020, operations at this locationwould improve from LOS E under the No-Action Alternative to LOS D under Alternative B4 as a result ofminor signal timing and phasing adjustment• Post Road (U.S. Route 1) at Coronado Road – In 2020, evening peak hour operations would improve fromLOS D under the No-Action Alternative to LOS C under Alternative B4. The improvements would resultprimarily from a shift in westbound traffic volume exiting the Airport to the newly created intersection ofPost Road at the new Post Road Gateway to the south.• Main Avenue at Groveland Avenue – In 2025, morning peak hour operations would improve from LOS Bunder the No-Action Alternative to LOS A under Alternative B4. In 2020, evening peak hour operationswould improve from LOS C under the No-Action Alternative to LOS B. In 2025, evening peak houroperations would improve from LOS D to LOS B. The improvements would result primarily from minortraffic signal timing changes.• Main Avenue at Industrial Drive – In 2020, evening peak hour operations at this relocated intersectionwould improve from LOS D under the No-Action Alternative to LOS B under Alternative B4. In 2025,evening peak hour operations would improve from LOS E to LOS B. The improvements would resultprimarily from minor traffic signal timing changes.• Main Avenue at Jefferson Boulevard – During the evening peak hour in 2020, overall intersection operationswould improve from LOS E under the No-Action Alternative to LOS D under Alternative B4 as a result ofminor signal timing and phasing adjustments.• Jefferson Boulevard at Coronado Road and Kilvert Street – In 2020, evening peak hour operations at thisrelocated intersection would improve from LOS D under the No-Action Alternative to LOS C underAlternative B4. In 2025, evening peak hour operations would improve from LOS E to LOS D. Theimprovements would result primarily from minor traffic signal timing changes.Chapter 5 - Environmental Consequences 5-138 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
