It should be noted that some projects have multiple beneficial project <br />elements and thus could be analyzed using more than one analysis technique (i.e., a project can <br />have both a congestion benefit and a safety benefit). However, for the purposes of this analysis, <br />project analysis was limited to the basis which best reflects the primary benefit and/or purpose of the <br />project. <br />Level of Service Analysis <br />Methodology <br />Table 1 summarizes the methodology and measure of effectiveness (MOE) that was used to evaluate <br />existing and future conditions for public facilities included within the 2020 TVTC Nexus Study. As <br />described in the prior section, the methodology and MOE selected were dependent on the type of public <br />facility being analyzed and the data available. <br />Table 1: Methodology and Measure of Effectiveness <br />Improvement <br />Type Facility Type Methodology Measure of Effectiveness <br />Roadway Capacity <br />Freeway HCM Freeway LOS (Density) <br />State Route HCM Highway LOS (Density) <br />Arterial ACTC Roadway Segment LOS (V/C) <br />Interchanges HCM Intersection LOS (Delay) <br />Transit All Facility Type TCQSM Service Frequency LOS <br />Safety All Facility Type HSM Safety Performance <br />Functions Crash Rate <br />Pedestrian/ <br />Bicycle All Facility Type Montgomery County Level of <br />Traffic Stress Level of Traffic Stress (LTS) <br />Intersection -HCM Intersection LOS (Delay) <br />Technology All Facility Type Qualitative Assessment Resultant Delay/Congestion <br />Reduction <br />Note: HCM = Highway Capacity Manual, ACTC = Alameda County Transportation Commission, LOS = Level of Service, <br />TCQSM = Transit Quality of Service Manual, HSM = Highway Safety Manual <br />Roadway Capacity <br />Analysis of roadway capacity projects was completed based on the HCM concept of Level of Service <br />(LOS). The HCM LOS for a roadway facility is a qualitative measure used to describe operational <br />conditions. LOS ranges from LOS A (free flow traffic with minimal delay) to LOS F (heavy congestion <br />operating near or over capacity). As discussed in the following sections, Freeway, State Route, and <br />Interchange projects were evaluated using methodologies defined in the HCM 6th Edition, while <br />arterial roadway analyses were completed based on a volume/capacity (V/C) methodology commonly <br />applied for project analyses undertaken by the Alameda County Transportation Commission (ACTC).
