Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 26 April 18, 2019 x Side-Street Left-Turns: Left-turn maneuvers from unsignalized side-streets are expected to become significantly more difficult under the forecast year 2040 traffic volumes. Lexington Station, Target South, Enterprise/Big O Tires/Arby’s, and Shannon Square driveways are all projected to experience side-street left-turn delays corresponding to at least LOS E during the midday and/or p.m. peak hours. x County Road E: Under forecast year 2040 p.m. peak hour traffic volumes, inefficient east/west split phasing causes unnecessary delay and queuing, particularly on the eastbound approach. 3.5 Identification of Deficiencies Based on the safety analysis, geometric considerations evaluated, preliminary traffic operations analysis, and discussions with Ramsey County, the following deficiencies have been identified: 3.5.1 Safety Deficiencies Gap Selection At the Lexington Avenue / Red Fox Road intersection, 19 of 20 reported right-angle/left-turn crashes occurred during midday or p.m. hours, with 15 of these 19 crashes involving southbound left-turning vehicles. This trend is evident throughout the Lexington Avenue corridor, with 34 of the 36 right-angle/left-turn crashes occurring during midday or p.m. hours. It can be concluded that heavier volumes and permissive “green ball” left-turn operation may be resulting in driver confusion/poor gap selection throughout the corridor. Rear-End Injuries Examining injury crashes throughout the Lexington Avenue corridor, 10 of the 17 injury crashes were rear-end crashes, with all 10 occurring during midday or p.m. hours. A continuous TWLTL throughout much of the corridor allows mainline left-turning motorists to exit through traffic prior to turning. However, only one intersection has a dedicated right-turn lane (northbound approach at Red Fox Road). High volumes, frequent driveway access, and a lack of right-turn lanes may be contributing to the increased number of rear-end crashes observed throughout the corridor. 3.5.2 Access Management Lexington Station / Target South / Enterprise-Big O Tires-Arby’s Currently, three side-street stop controlled driveways are located within 500 feet of each other between the signalized intersections of Lexington Avenue / Red Fox Road and Lexington Avenue / Grey Fox Road. Lexington Station and Target currently both have connections to Red Fox Road to the north; however, the existing Lexington Avenue driveway for Enterprise-Big O Tires-Arby’s is the only access to these businesses. A signal at the Target South intersection would provide an opportunity to consolidate driveway access to businesses on the west side of Lexington Avenue.
