intersection is experiencing a LOS of 'T"' during both the AM and PM peak hours. The Santa Clara Avenue intersection during the AM peak hour and the intersections at 17th Street and 1st Street during the PM peak how, are experiencing LOS of "E°. These intersections are operating at capacity levels in which motorists are experiencing a great deal of delay. T"he information portrayed in Tables 1 and 2 clearly shows that Bristol Street and the major intersections within project area are presently operating beyond their designed capacities. An additional physical feature limiting the traffic carrying capacity of Bristol Street is the 53 -foot wide bridge across Santiago Creek. As presently con- structed, the bridge cannot accommodate more than four through lanes and represents a major bottleneck. Existing operational conditions along Bristol Street have contributed to the occurrence of traffic accidents. Between January 1, 1986 and May 11, 1987, a total of 1,108 traffic incidents were reported along Bristol Street between La Veta Avenue and MacArthur Boulevard. Specifically within the project area, between Memory Lane and Warner Avenue, a total of 918 accidents were reported during this 16 -month period. A total of 35 incidents involved damage to City property; 29 involved pedest- rians; 26 involved bicycles; 41 involved collisions with parked cars (although on- street parking is not permitted in the project area); and 22 involved motor - cycies. A total of 12 head -on collisions were also reported in the project area, as were 155 incidents involving left -turn movements. These latter two statistics appear to indicate the need for improved traffic controls, by such means as medians to separate opposing traffic, additional signalization, and left -turn restrictions at minor intersections. It should be noted that the accident data cited above was derived from the City of Santa Ana Public Service Agency's computer files. The proposed" improvements will serve to alleviate existing congestion problems and will help accommodate future traffic on this important north- south arterial, The project will result in the establishment of a safer, more efficient roadway with a substantial reduction in delays experienced by motorists, I -13 75C -36
