4.2 TRAFFIC AND CIRCULATION West of the project vicinity, it is a two-lane highway and to the east SR-12 widens and has traffic signal , controls at intersections through the City of Lodi. Lower Sacramento Road is a two-lane arterial oriented in a north-south direction. Located just east of the project site this road extends south from the Town of Galt to the City of Stockton. Forest Lake Road is a two-lane road extending west from Lower Sacramento Road across the northern boundary of the proposed project site with no outlet to the west. The road is lightly traveled, serving primarily rural properties along its length, and would directly access the proposed project. Peltier Road is a two-lane,east-west oriented arterial extending east from I-5 past SR-99. Peltier Road would serve as the primary access route to the project site (via Davis Road) for vehicles using either freeway. Davis Road is a two-lane arterial extending south of Peltier Road across SR-12 to Stockton. Davis Road extends north of Peltier Road a short distance serving a few homesites, and then terminates. The project proposes to extend Davis Road north to serve as the primary access. A bridge would be constructed across the Mokelumne River in conjunction with development of the project. Turner Road is another two-lane arterial oriented in an east-west direction between Peltier Road and SR- 12 and provides access to I-5 and SR-99 as well as to the Town of Woodbridge. Level of Service Concept and Study Intersections The Level-of-Service (LOS) scale is the primary indicator for traffic operation performance at ' intersections. At a signalized intersection, LOS is determined by calculating the volume of conflicting traffic movements at an intersection during one-hour and dividing that total by the capacity designed to accommodate those turning movements. The resulting calculations are expressed by a volume/capacity (v/c) ratio and LOS ratings which range from LOS A to LOS F. The LOS A to F range describes increasing levels of traffic demand, and corresponding increases in delays and deterioration of service. LOS A represents free-flow conditions with little or no delay (zero to five seconds) at signalized intersections. LOS E characterizes extremely unstable flow conditions with volumes at or near the designed capacity. Vehicles are likely to experience major delays (40 to 60 seconds) crossing an intersection. Under LOS E, minor incidents may lead to forced flow conditions (LOS F), resulting in long queues backing up from all approaches to intersections. At intersections where all of the approaches are stop-sign controlled,the LOS definitions reflect overall delays similar to those described for signalized locations. however, if volumes are substantially 4.2-2
