Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 38 April 18, 2019 4.6.2 Key Decision Factors Operations were improved across all peak hours. Key decision factors for each intersection are: Lexington Avenue & Red Fox Road At the Lexington Avenue / Red Fox Road intersection where the southbound approach was the primary concern (southbound left-turns in particular), expanding the intersection to accommodate dual southbound left-turn lanes was a key factor in managing queues. Additional operational benefits are achieved through the separation of left-turn/through/right-turn movements into dedicated lanes, while providing permissive FYA left-turn operations for all approaches during off-peak hours. An additional improvement recommended in conjunction with the dual SB left-turn lanes involves extending the eastbound Red Fox Road right-turn lane trap approximately 265 feet east to the second Target driveway, thus minimizing potential merging conflicts. However, it should be noted that this recommended improvement is not expected to be implemented as part of the Lexington Avenue reconstruction. Therefore, operational and safety performance along eastbound Red Fox Road should continue to be monitored, and the recommended lane extension made in the future if performance is determined to be inadequate. Lexington Avenue & Target South At the Lexington Avenue / Target South intersection where side-street operations were the primary concern, the installation of a new traffic signal facilitated operational and safety improvements. Furthermore, consolidating the Lexington Station and Enterprise/Big O Tires/Arby’s driveways to oppose Target South would further improve safety along the Lexington Avenue corridor. Lexington Avenue & Grey Fox Road At the Lexington Avenue / Grey Fox Road intersection, improving side-street operations while also improving coordination along the Lexington Avenue corridor was the key factor in restriping and resigning the eastbound/westbound lane geometry. These operational improvements allowed consideration of access restrictions at the Shannon Square driveway to the south. Lexington Avenue & County Road E At the Lexington Avenue / CR E intersection, eliminating eastbound/westbound split signal phasing while providing protective/permissive FYA left-turn operations for the entire intersection was a key factor in improving operations.
