Lexington Station Phase 3 Traffic Study February 26, 2021 Page 14 The following information summarizes the operational issues that warrant consideration as development occurs: x Lexington Avenue/Target Road/Proposed Development Access: o Without a future traffic signal, the cross-street approaches (including the one providing outbound movement from the proposed development) is expected to be over capacity, with side-street stop delays greater than three (3) minutes and very significant queuing spillback. o The proposed eastbound approach vehicle queuing storage is limited (approximately 100 feet). Infrequently, when this storage is filled, queues are expected to extend into the parking lot, which may infrequently and for very brief periods of time, block parking maneuvers to and from the southernmost parking stalls along the east face of the building. o Note that with a future traffic signal, eastbound queues are expected to be reduced significantly, however, they may continue to infrequently and for very brief periods of time, extend beyond the limited storage during the p.m. peak hour. Warrant Analysis Based on the existing and future capacity issues at the Lexington Avenue/Target Road intersection, a cursory warrant analysis was performed under 2023 no build and 2023 build conditions to determine if a traffic signal would be warranted. Results of the warrant analysis indicate that a peak hour warrant is expected to be met under both the 2023 no build and build conditions. It should be noted that due to the difficulty of the movement, the westbound left-turn volumes are likely less than the demand. Therefore, while only the peak hour warrant is met under 2023 conditions, if the demand at the intersection was realized, the intersection may meet additional warrants (i.e. four-hour/eight-hour). In addition, three-minute side-street stop delays are considered unacceptable and may cause safety issues at the intersection, therefore, a traffic signal is recommended as part of the Lexington Avenue reconstruction project to facilitate the access management strategy along the corridor.
