Grey Fox Road Redevelopment – Arden Hills <br />Traffic Impact Analysis │ July 2021 <br />8 <br /> <br />The two site accesses were modeled with the existing geometry and intersection control. The intersection <br />of Lexington Avenue & Grey Fox Road used the geometry and intersection control from the Lexington <br />Avenue Reconstruction (I-694 to CR E) project. The traffic volumes are provided in Exhibit 4. <br />The results of the analysis are provided in Table 3. <br />Table 3 – Opening Year (2023) No-Build Intersection Analysis <br />Intersection Control Approach <br />Operations by Movement Overall Intersection Left Through Right <br />Delay <br />(sec/veh) LOS Delay <br />(sec/veh) LOS Delay <br />(sec/veh) LOS Delay <br />(sec/veh) LOS <br />AM Peak Hour <br />Lexington Avenue <br />& Grey Fox Road Signal <br />EB 41.6 D 33.2 C 6.4 A <br />6.3 A WB 42.0 D 38.6 D 6.6 A <br />NB 6.0 A 3.3 A 0.8 A <br />SB 5.8 A 3.1 A 0.8 A <br />Grey Fox Road & <br />Site Access 1 (East) <br />Side <br />Street <br />Stop <br />EB 0.9 A 0.7 A 0.1 A <br />6.3 A WB 1.0 A 0.5 A 0.5 A <br />NB 4.3 A - - 2.9 A <br />SB 5.5 A 6.3 A 2.8 A <br />Grey Fox Road & <br />Site Access 2 <br />(West) <br />Side <br />Street <br />Stop <br />EB 1.4 A 0.2 A 0.1 A <br />6.2 A WB - - 0.2 A 0.1 A <br />NB 4.7 A 6.2 A 2.4 A <br />SB 3.1 A 4.0 A 2.6 A <br />PM Peak Hour <br />Lexington Avenue <br />& Grey Fox Road Signal <br />EB 38.2 D 26.6 C 8.9 A <br />10.6 B WB 35.4 D 35.0 C 7.5 A <br />NB 13.3 B 8.4 A 1.5 A <br />SB 14.0 B 6.9 A 1.3 A <br />Grey Fox Road & <br />Site Access 1 (East) <br />Side <br />Street <br />Stop <br />EB 1.1 A 1.4 A 0.1 A <br />6.8 A WB 1.3 A 0.5 A 0.4 A <br />NB 5.7 A 5.6 A 5.6 A <br />SB 2.3 A 6.8 A 3.3 A <br />Grey Fox Road & <br />Site Access 2 <br />(West) <br />Side <br />Street <br />Stop <br />EB 1.8 A 0.5 A 0.3 A <br />5.8 A WB 2.4 A 0.3 A 0.2 A <br />NB 4.4 A 5.8 A 3.0 A <br />SB 3.6 A 5.7 A 2.8 A <br />For Side Street Stop intersections, the worst individual movement was reported for the overall intersection LOS <br />Based on the Opening Year (2023) No-Build capacity analysis, the study intersections are anticipated to <br />operate at LOS B or better in the AM peak hour and in the PM peak hour. Additionally, all individual <br />movements are anticipated to operate at a LOS D or better. The SimTraffic reports are provided in <br />Appendix D. All 95th percentile queues are anticipated to remain within their respective storage bays. <br />OPENING YEAR (2023) BUILD CONDITIONS <br />Opening Year (2023) Build conditions were analyzed to determine any traffic impacts from the addition of <br />the site traffic to the study intersections. The site accesses were modeled as side street stop control. <br />Opening Year (2023) Build turning movement volumes were developed by adding the site trips in Exhibit <br />7 to the Opening Year (2023) No-Build turning movement volumes in Exhibit 4. The Opening Year (2023) <br />Build turning movement volumes are shown in Exhibit 8. The results of the analysis are provided in Table <br />4.
