Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 27 April 18, 2019 Shannon Square Driveway Shannon Square businesses currently have a connection to Lexington Avenue via the Cub Foods parking lot and Grey Fox Road to the north, in addition to the direct driveway access along Lexington Avenue located approximately 550 feet to the south of Grey Fox Road. Due to frequent significant delay in executing the eastbound left-turn maneuver from Shannon Square, many outbound motorists choose to route through the Cub Foods parking lot to access the traffic signal at Grey Fox Road. This is exhibited by the disparity in traffic volumes between the eastbound left-turn maneuver and the southbound right-turn maneuver, as the eastbound left-turn maneuver exhibits significantly lower volumes over all time periods. 3.5.3 Operational Deficiencies Lexington Avenue & Red Fox Road Results of the traffic operations analysis indicate that the Lexington Avenue / Red Fox Road intersection is expected to operate at overall LOS F under year 2040 no build p.m. peak hour traffic volumes. Limited southbound left-turn capacity and inadequate spacing to the I-694 EB Ramp Terminal intersection create queuing issues, with southbound queues frequently extending into the I-694 EB Ramp Terminal intersection during peak hours. A similar problem affects the northbound approach to the I-694 EB Ramp Terminal intersection, as through queues frequently block access to the adjacent right-turn lane, causing the combined queues to extend to Red Fox Road. Lexington Avenue & Grey Fox Road Results of the traffic operations analysis indicate that the Lexington Avenue & Grey Fox Road intersection is expected to operate at overall LOS E under year 2040 no build p.m. peak hour traffic volumes. However, northbound and southbound movements operate at LOS C or better. Higher side-street volumes/permissive-only left-turn movements result in long delays and queues for the shared eastbound left-turn/through lane. Lexington Avenue & Driveway Access Results of the traffic operations analysis indicate that throughout the Lexington Avenue corridor driveways are expected to perform poorly under year 2040 no build p.m. peak hour traffic volumes. Most eastbound and westbound approaches are expected to operate at LOS F, with only the Lexington Avenue / Enterprise-Big O Tires-Arby’s right-turn movement operating at LOS B as a low volume movement.
