DKS Associates The directional orientation of trips to and from the study area was based on overall peak hour area wide circulation patterns and the project location in relationship to regional service and employment concentrations. About 29% of the total traffic is distributed northbound toward the SR -22 and I -5 and another 29% is distributed southbound toward SR -55 and SR -405. The easterly and westerly portions were assigned 21 % each. Trips to and from the project study area were assigned to logical access routes based upon the trip distribution percentages discussed above. 53 MIDBLOCK OPERATION The estimated future daily operational analysis summary for the existing, future without Specific Plan and future with Specific Plan is shown in Table 54. There are no significant changes in levels of service along Bristol Street in the study area with Specific Plan in comparison to without the Specific Plan. 5.4 INTERSECTION OPERATIONAL ANALYSIS The intersection operational analyses were done for peak hour conditions. The PM peak hour represents the worst case situation, although the level of service does not differ drastically from AM peak hour conditions. This might be due to a good balance in land use that exists between residential and commercial development. The impacts on the intersections along Bristol Street due to the Specific Plan in comparison with the existing, future without Specific Plan, and future with Specific Plan are shown on Table 5 -5 and Table 5-6_ For the 13 study intersections, there will be no significant changes in quality of traffic operation on any of the intersections in comparison with the future condition without Specific Plan. All intersections are found to be functioning at a satisfactory level of service. 28657.P90223W. Rpr 28
