Table 3 shows the <br /> 85th percentile or prevailing speed along the corridor.As shown, the 85th percentile is generally <br /> within 5 mph of the posted speed limit. <br /> Table 3. 85th Percentile Speeds by Study Segment <br /> 85th Percentile Speed(miles per Vehicles Per <br /> Day Traveling <br /> Over 40 mph <br /> Baker Street to Shelton Street 41 40 40 5,899 (15%) <br /> Parton Street to Ross Street 41 41 41 7,158 (18%) <br /> West of Spurgeon Street 37 35 36 2,087 (6%) <br /> East of Garfield Street 42 44 43 8,687 (26%) <br /> Standard Avenue to Grand Avenue 42 40 41 6,017 (18%) <br /> West of Wright Street 43 42 43 8,160 (24%) <br /> West of Cabrillo Park Drive 40 38 39 2,754 (11%) <br /> Golden Circle Drive to Tustin 42 40 41 3,525 (18%) <br /> Avenue <br /> While the 85th percentile speeds are within a reasonable range of the posted speed limit, many <br /> vehicles were recorded traveling at or above the posted 40 mph speed limit. These excessive <br /> speeds tend to occur outside of the peak hours when the volume on the roadway is well below <br /> capacity.The lack of traffic and friction that is caused by the proximity of vehicles close to one <br /> another results in drivers traveling faster than the posted speed limit—even when they are not <br /> aware they are doing so. <br /> City Council 12 —23 5/5/2 6 <br />
