Draft Supplemental Environmental Impact Report Page IV.B-3 Forward Inc. Landfill 2018 Expansion Project Public Transit Transit service in the general vicinity of the Forward Landfill is provided by the San Joaquin County Regional Transit District (RTD). RTD provides service between Stockton and the airport,but the nearest route is at the Route 99/Arch Road interchange. No RTD or other transit lines extend into the study area. Intersection Operations Level of Service Concept The operating conditions of intersections experienced by motorists are described as"levels of service" (LOS). Level of service is based on several factors, including: • traffic volumes, • intersection lane configurations, • design and type of traffic control, • speed and travel time, • traffic interruptions, • freedom to maneuver, and • driving comfort and convenience. Levels of service may be expressed qualitatively with letters "A" through "F" from best to worst, which cover the entire range of traffic operations that might occur. Levels of service A through D generally represent traffic volumes at less than roadway capacity, while LOS E represents traffic volumes at or near roadway capacity, and LOS F represents over-capacity or forced flow conditions. Two sets of LOS calculation methods were used for intersection capacity analysis in the study; one for signalized intersections and the other for the non-signalized intersections. For signalized intersections, traffic LOS is determined based on the average delay per vehicle for the entire intersection as a whole. For the non-signalized intersections,traffic LOS is determined based on the average vehicle delay for approaches controlled by stop signs or yield signs at minor streets. Through traffic movements on major street approaches were evaluated but are not the determining factor intersection LOS. The study methodology was selected by PHA based on input from both the City of Stockton and San Joaquin County staff. Generally,this study follows County Traffic Study Guidelines (San Joaquin County,2008),but because the project is within the City of Stockton's sphere of influence, a 2035 horizon year for cumulative analysis was used per City guidelines.Tables IV.B-1 and IV.B-2 provide a brief description of LOS for each category.
