along Bristol Street revealed the growth in traffic to be approximately one percent per year. In the Five -Year Transportation Study Update to 1990 prepared by Basmaciyan- Darnell, Inc.; June 1985, the projected increase in area -wide traffic volumes, south of the project area, was anticipated to be greater than one percent per year. The volume of traffic on Bristol Street north of Warner Avenue is however consistent with a one percent per year growth rate. It was assumed that in the year 2006, all roads would be built out to their ultimate widths, as designated on the Orange County General Plan - Master Plan of Arterial Highways ComComponent, County of Orange, Environmental Management Agency, 1982. Future Roadway Link Cap&QIty Without Widening ow Evaluation of the operating conditions Bristol Street would experience under +„ future year 2006 traffic volumes was based upon the same methodology as was described under Section I. Table 1 in Section I summarizes the project traffic volumes on each link with their corresponding levels of service. Under the "no- project" alternative, each link of Bristol Street from Memory Lane to Warner Avenue would experience a Level of Service of "P. Traffic on Bristol Street would be extremely congested and motorists would experience a great deal of delay at all major intersections. s. Due to the limiting nature of a road system, there is an upper limit to the volume of traffic which any roadway can carry. When traffic volume demand exceeds these limits the remaining traffic will be forced onto adjoining roads in the circulation system and affect their corresponding road capacities. The traffic projections on Bristol Street north of McFadden Avenue are expected to exceed the theoretical maximum roadway capacity for a four lane undivided M. highway and the remaining traffic is expected to seek alternative routes. However, because there are many variables that can affect the roadway capacity, no attempt was made to quantify the theoretical maximum. The traffic volumes projected for the future year 2006 may, therefore, be higher than the roadway can actually accommodate. Future Intersection Capacity Without Widening ICU calculations were also performed at each signalized intersection for future ,. traffic volumes under existing lane configurations. Table 4 in Section I summarizes the anticipated V/C and intersection LOS values that are anticipated under the no widening alternative. ... IV -60 PP .w
