T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationSix locations with LOS E or LOS F capacity constraints under the No-Action Alternative would continue tooperate at LOS E or LOS F levels under Alternative B4:• Post Road (U.S. Route 1) at Lincoln Avenue – During the evening peak hour in both 2020 and 2025, thisintersection would operate at LOS F under the No-Action Alternative and under Alternative B4.• Post Road (U.S. Route 1) at Partially Relocated Airport Road and Ann & Hope driveway – During theevening peak hour in 2025, this intersection would operate at LOS E under the No-Action Alternative.Under Alternative B4, the relocated intersection would continue to operate at LOS E.• Airport Road at Evergreen Avenue – During the evening peak hour in 2020 and 2025, this intersectionwould operate at LOS F under the No-Action Alternative and under Alternative B4.• Airport Road at Commerce Drive – During the evening peak hour in both 2020 and 2025, this intersectionwould operate at LOS F under the No-Action Alternative and under Alternative B4.• Airport Road at Warwick Avenue – During the evening peak hour in 2020, this intersection would operateat LOS E under the No-Action Alternative and under Alternative B4. In 2025, this intersection wouldoperate at LOS E during the morning peak hour under the No-Action Alternative and under Alternative B4.In 2025, this intersection would operate at LOS F during the evening peak hour under the No-ActionAlternative and at LOS E under Alternative B4.• Main Avenue at Jefferson Boulevard – In 2025, this intersection is projected to operate at LOS E during themorning and evening peak hours under the No-Action Alternative and under Alternative B4. This isprimarily the result of heavy volumes on all approaches where the signal is operating at or near capacity.Alternative B4 would result in LOS E or LOS F conditions at two locations:• Post Road (U.S. Route 1) at Relocated Delivery Drive – Relocating Delivery Drive would create a newunsignalized driveway along Post Road. The only vehicles using Delivery Drive would be Airport deliveryvehicles (approximately 40 vehicles per hour during the morning and evening peak hours in both 2020 and2025). General traffic would be prohibited from entering or exiting the Airport at this location. Becausetraffic volumes on Delivery Drive are low, a traffic signal is not warranted or recommended at thisintersection. Without a signal, vehicles exiting Delivery Drive would operate at LOS D in the morning peakhour and at LOS F in the evening peak hour in 2020 and 2025. However, the LOS F only applies to the40 vehicles exiting Delivery Drive, not to the vehicles on Post Road (an average of one vehicle every minuteand a half). General traffic on Post Road would not be affected. 365• Post Road (U.S. Route 1) at Donald Avenue – Under Alternative B4, the ramp at Aviation Avenue (oppositeDonald Avenue) would be closed and the existing traffic signal removed. The signal is needed underexisting conditions in order to facilitate the flow of Airport-bound traffic from the Airport Connectorturning right on Post Road, then left on Aviation Avenue. Once Aviation Avenue is closed, the traffic signalwould no longer be warranted under Alternative B4. Removing the traffic signal would likely improve365 Of the 40 vehicles, approximately five vehicles are expected to turn left and the remaining 35 vehicles are expected to turn right, based on observed trafficmovements. The 40 vehicles per hour average to one vehicle every minute and a half.Chapter 5 - Environmental Consequences 5-139 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
