DKS Associates Memory Lane West of Bristol Street, Memory Lane is an 84 -foot wide primary arterial highway that is striped for two lanes in each direction with a two -way left -turn lane. At Bristol Street, the west approach of Memory Lane is striped with a left -turn lane, an optional left and through lane and two right -turn lanes. This section of Memory Lane has a posted speed limit of 40 MPH and is a designated truck route. It has an estimated average daily traffic volumes of 30,800 vehicles. East of Bristol Street, Memory Lane is also 84 feet wide and striped for two lanes in each direction with a continuous two -way left -tum lane. At Bristol Street, the east approach of Memory Lane is striped with a left -turn lane, a right -turn lane and two through lanes. Traffic volume on this section of Memory Lane is estimated at 12,300 vehicles per day, and the posted speed limit of 40 MPH. Trucks over three tons are not allowed on Memory Lane, east of Bristol Street. Traffic signal phasing at the Bristol Street/Memory Lane intersection is split in the east -west direction. Signal phasing also provides for an eastbound right -turn overlap with the northbound protected left -turn phase. Pedestrian crossing is prohibited across the south leg of Bristol Street- 3.2 MIDBLOCK CAPACITY ANALYSIS The existing average daily traffic volumes for various segments of Bristol Street are based primarily upon the volumes provided in the Bristol Street Widening Project (EIS) and its associated traffic study. Using roadway capacity standards developed by the Orange County Environmental Management Agency, levels of service were determined. Level of service (LOS) is a qualitative description of midblock operating conditions which ranges from A (excellent) to F (failure). Table 3 -1 provides a detailed explanation about roadway capacity values. The existing average daily traffic volumes for various segments of Bristol Street within the study area and the results of the capacity analysis are shown on Table 3 -2. All segments of Bristol Street within the study area, except south of St. Gertrude Place to Warner Avenue, are currently functioning at level of service F. 3.3 INTERSEMON CAPACITY ANALYSIS Intersection capacity analyses utilizing the Intersection Capacity Utilization (ICU) methodology are performed on 13 major intersections along Bristol Street. The most recent traffic volumes (1990) at each intersection were gathered from the City of Santa Ana for typical AM and PM peak traffic periods. The existing lane configurations used for the 13 intersections analyzed are shown in Figure 3 -2. 28657.P90223xaRpr 10
