(or 2010 HCM at the City's request) and Synchro Analysis Software. The traffic study will include the <br /> following traffic study scenarios: <br /> a. Existing Conditions—Existing operating conditions at the study intersections will be <br /> estimated based on the field reconnaissance, data collection, and methodologies <br /> described above. In addition, a qualitative review of transit, bicycle and pedestrian <br /> facilities will be included. <br /> The Existing conditions will include an analysis of intersection Levels of Service, the <br /> Mitigations identified in the City's Traffic Impact Fee, and the Level of Service with <br /> Mitigation in place. <br /> b. Existing+Approved Projects (Background Conditions)—These operating conditions will <br /> be analyzed based on the addition of net-new trips related to pending or approved <br /> projects as identified by City staff to the Existing Conditions analysis. The traffic analysis <br /> for this scenario will include trip estimates,trip distribution patterns, and intersection <br /> LOS analysis for the study intersections. <br /> The Existing+ Approved Projects conditions will include an analysis of intersection Level <br /> of Service, the Mitigations identified in the City's Traffic Impact Fee, and the Level of <br /> Service with Mitigations in place. <br /> c. Existing+Approved Projects + Project Conditions—Operating conditions will be <br /> analyzed based on a forecast of net-new trips associated with the proposed project <br /> added to the Background Conditions traffic volumes. The traffic analysis for the Project <br /> scenario will include trip estimates, trip distribution patterns, and intersection LOS <br /> analysis for the study intersections. <br /> The Existing +Approved Projects+ Project conditions will include an analysis of <br /> intersection Levels of Service, impact identification, significance criteria, mitigation <br /> measures, effectiveness of mitigations measures, and responsibility for implementation. <br /> 5. Traffic Signal Warrant Analysis <br /> A peak-hour traffic signal warrant analysis will be conducted using existing and project conditions to <br /> determine if signalization of unsignalized intersections is warranted. <br /> 6. Queuing Analysis <br /> Queue lengths will be analyzed for each lane to provide the distance that vehicles will back up in each <br /> direction approaching an intersection.The 95`h percentile queue length will be used to account for <br /> fluctuations in traffic indicating the longest queue length that would be expected 95 percent of the time <br /> during the peak period, with traffic volumes and related queuing at or less than the 95`h percentile <br /> queue most of the time. <br /> Ninety-fifth percentile queuing will be checked (per the City's Standards of Significance) under the <br /> Existing+ Approved Projects and Existing+Approved Projects+ Project a.m. and p.m. peak hour <br /> conditions. <br />
