Dowling Associates, Ins. 1 i, Transportation Engineering • Planning • Research • Education Existing +Approved + Project Conditions With Loop Road This analysis case includes a perimeter loop road adjacent to the project site. The loop road would intersect Stanley Boulevard at the project's easternmost driveway, run in a north-south orientation to the east of the project, then turn in an east-west orientation to the south of the project and tie in to the existing Nevada Court. Project trip assignment was manually adjusted to reflect the following turn restrictions: (a) westbound left turns from Stanley Boulevard to Bernal Avenue would be prohibited (and would instead use the loop road); (b) northbound left turns out of the loop road to westbound Stanley Boulevard would be prohibited. The project trips assigned to the turning movements at the study intersections under the Existing+Approved+project With Loop Road conditions are shown in detail in Figure 5 (and in Appendix Table A-4). Construction of the Loop Road was assumed to affect traffic circulation patterns at the following intersections only, relative to Existing+Approved+project Without Loop Road conditions: (7) Bernal & Nevada/Loop Road (8) Bernal & Utah (32) Stanley & Va1leyBernal (45) Stanley & Home Depot east driveway/Loop Road The LOS results for the Existing+Approved+project With Loop Road conditions at the study intersections identified above are shown in Table 5. The analysis assumes the intersection of Bernal & Nevada/Loop Road, which would meet the peak hour signal warrant, would be signalized as part of the construction of the Loop Road. The intersection of Stanley & Home Depot east driveway/Loop Road (intersection 45) degrades from LOS B to LOS F in the PM peak hour with the Loop Road. Colstruction of the Loop Road would add significant traffic to the westbound left-turn movement at this intersection, which was analyzed as a minor approach stop-controlled intersection. With the exception of the four locations identified above, the study intersections would operate the same with or without the Loop Road.
