3200 Hopyard Road Redevelopment – Transportation Assessment January 2, 2024 4 The land use scenarios assumed for this study are as follows: 1. Existing Conditions: This scenario examines the study intersections based on typical peak hour volumes in the recent years. The turning movement counts were collected in March and April 2023 and provided by City staff. 2. Existing plus Project Conditions*: This scenario adds traffic generated by the proposed development to the Existing Conditions. 3. Approved Conditions: This scenario examines the study intersections based on typical peak hour traffic volumes with the addition of traffic from Approved projects. 4. Approved plus Project Conditions*: This scenario adds traffic generated by the proposed development to the Approved Conditions. 5. Buildout Conditions: This scenario examines the study intersections based on projected peak hour traffic volumes in the future, with buildout of the General Plan. 6. Buildout plus Project Conditions*: This scenario adds traffic generated by the proposed development to the Buildout Conditions. City of Pleasanton staff provided TJKM with Synchro analysis files of the study area for Existing, Approved, and Buildout Conditions, for the a.m. and p.m. peak hours. TJKM updated the Existing Conditions model scenarios with the provided 2023 traffic volumes and corrected minor errors in lane geometry but did not otherwise alter any other scenarios. * Of note, this memorandum was updated to revise the trip generation comparison. Originally, memo excluded the daycare component from existing conditions. Based on comments from City staff, the trip generation comparison was updated to include the day care facility but the LOS analyses did not need to be updated (as the LOS analyses herein would be conservative and inclusion of the daycare component would not change the memorandum’s findings). INTERSECTION LEVEL OF SERVICE METHODOLOGY Intersection Level of service (LOS) is a qualitative description of intersection operations and is reported using an A through F letter rating system to describe travel delay and congestion. LOS A indicates free flow conditions with little or no delay, and LOS F indicates severely congested conditions with excessive delays and long back-ups. For consistency, due to limitations in the newest LOS methodology in evaluating the signal timing at two of the existing signalized intersections, the methodology described below was applied to all intersection. Signalized Intersections: The signalized study intersections were analyzed using the Transportation Research Board’s (TRB) Highway Capacity Manual 2000 (HCM) operations methodology for signalized intersections described in Chapter 16. Peak hour traffic operational conditions for signalized intersections are reported as average control delay for the overall intersection in seconds per vehicle with corresponding LOS. Table 3 summarizes the level of service definitions for stop controlled intersections along with the associated delay.
