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