The Pre-Pilot <br />data was collected in May 2015 and the Post-Pilot data was collected in May 2016. <br /> <br />The collected data was analyzed to identify the following: <br /> <br /> 85th percentile speed, which is defined as the speed 85 percent of drivers are moving at or <br />below, <br /> 50th percentile speed is the median speed – 50 percent of drivers are driving at or below that <br />speed, and 50 percent of drivers are driving above that speed, <br /> Percent of vehicles traveling above the posted speed limit, and <br /> Percent of vehicles traveling 10 mph or more over the posted speed limit. <br />Outcomes: <br />85th Percentile Speed <br /> <br />Table 15 shows the comparison of daily versus off-peak 85th percentile speeds on Jefferson Avenue <br />between Highland Avenue and Alameda de la Pulgas, by direction. The data shows that the reductions <br />of 85th percentile speed are similar between the daily period and the off-peak hours. The decreases all <br />8.A. - Page 29
