T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationBetween Coronado Road and Haverford Road, a 0.9 percent increase is expected in 2020 and a1.2 percent increase is expected in 2025; Between the Airport Connector and Coronado Road, a 1.2 percent increase is expected in 2025;• Jefferson Boulevard – Traffic on Jefferson Boulevard between Airport Connector and Coronado Road wouldincrease by 2.7 percent in 2025. No change is expected in 2020; and• Main Avenue – Traffic on Main Avenue between Post Road and Industrial Drive would increase by1.7 percent in 2020 and by 0.7 percent in 2025.Effects on VMT and VHT – 2020/2025Alternative B2 would result in decreases in VMT and VHT in both 2020 and 2025 compared to the No-ActionAlternative. Under Alternative B2, VMT would decrease by 1.2 percent in both 2020 and 2025. VHT woulddecrease by 2.4 percent in both 2020 and 2025. VMT and VHT would decrease because Alternative B2 provides amore direct connection to Route 37, which shortens trip lengths for east-west traffic from the Route 37interchange or points north on Post Road. Moreover, this east-west link from Route 37 to Fully RelocatedAirport Road would be uninterrupted, whereas today this traffic flow passes through the busy signalizedintersection of Post Road and Airport Road.Effects on Peak Hour Traffic Flow (Level of Service) – 2020/2025Morning and evening peak hour traffic flow would improve at seven locations under Alternative B2 whencompared with the No-Action Alternative:• Post Road (U.S. Route 1) at Lincoln Avenue – During the evening peak hour in both 2020 and 2025, overallintersection operations would improve from LOS F under the No-Action Alternative to LOS C underAlternative B2. During the morning peak hour, intersection operations would improve from LOS C underthe No-Action Alternative to LOS B under Alternative B2 in both years. While the intersection is projectedto experience increases in traffic volume when compared to the No-Action Alternative, Alternative B2would modify intersection geometry and signal timing and coordination as part of Fully Relocated AirportRoad. These improvements would result in operational improvements. These modifications includedesignating Lincoln Avenue as one-way westbound between Post Road and Fully Relocated Airport Road.Vehicles destined to Fully Relocated Airport Road from Post Road would turn at this intersection, andvehicles traveling westbound on Fully Relocated Airport Road that are destined to Post Road wouldintersect with Post Road under the existing Route 37 ramp interchange.• Fully Relocated Airport Road at Commerce Drive – During the 2020 and 2025 evening peak hours, theoverall intersection operations would improve from LOS F under the No-Action Alternative to LOS Dunder Alternative B2. The improvements are primarily a result of geometric and signal upgrades at thisintersection associated with Fully Relocated Airport Road.• Existing Airport Road at Warwick Avenue – During the 2020 morning and evening peak hours, operationsat this location would improve from LOS E under the No-Action Alternative to LOS C under Alternative B2.Chapter 5 - Environmental Consequences 5-129 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
