Pock Lane Residential Traffic Impact Study <br /> 5.0 CUMULATIVE NO-PROJECT • • (2040) <br /> The Cumulative No-Project Conditions analysis forecasts how the study area's transportation system <br /> would operate with the growth and changes of the surrounding community by the year 2040. Corridor <br /> volumes on Pock Lane, 81" Street, and Mariposa Road in the immediate project vicinity were obtained <br /> from baseline year 2015 and horizon year 2042 in the SJCOG traffic model. Based on the growth in these <br /> corridor volumes, an annual compounding growth rate of 0.8 percent per year was applied to Existing <br /> Conditions to project future 2040 traffic volumes. <br /> Figure 10 shows projected turning movement volumes at the study intersections for Cumulative <br /> Conditions for a.m. and p.m. peak hours. <br /> 5.1 INTERSECTIONS LEVEL OF SERVICE ANALYSIS—CUMULATIVE NO-PROJECT CONDITIONS <br /> The intersection LOS analysis results for Cumulative No-Project Conditions are summarized in Table 8. <br /> Under this scenario, all but two intersections would continue to operate at acceptable LOS D or better. <br /> The stop-controlled intersection of Pock Lane & Mariposa Road would degrade to LOS F during the p.m. <br /> peak hour, with a substantial increase in average delay on the northbound (controlled) approach <br /> compared to Existing Conditions. The all-way stop intersection of Pock Lane & Boeing Way would <br /> degrade to LOS E in the a.m. peak hour. <br /> A peak hour signal warrant analysis was also conducted for the unsignalized intersection of Pock Lane & <br /> Mariposa Road,to determine if a traffic signal is warranted.A signal is not warranted at this intersection <br /> during either peak hour. LOS and peak hour signal warrant worksheets are provided in Appendix E. <br /> Page 129 <br /> TJ KM <br />
