It should be noted that given the large sample size for each segment <br />(over 15,000 samples) that the results are statistically significant. The data shows more than a 99.97 <br />percent probability that the reduction in speeds is due to the improvements. <br /> <br />Farm Hill Boulevard between Eden Bower Lane and Lonesome Pine Road had the highest speeds with <br />a pre‐pilot 85th percentile speed of 45.9 mph in the westbound direction (going uphill towards I‐ 280) <br />and 47.5 mph in the eastbound direction (going downhill towards downtown). After the pilot, these <br />speeds decreased by seven percent – but are still well above the posted speed limit of 35 mph. Between <br />McGarvey Avenue and Jefferson Avenue, 85th percentile speeds are either at the speed limit or slightly <br />below the speed limit – at 35 mph going towards I‐280 and 32.4 mph going towards downtown. On <br />Jefferson Avenue, between Highland Avenue and Alameda de las Pulgas, the reductions were eight <br />percent going towards I‐280 and nine percent going towards downtown but speeds continued to be <br />above the posted speed limit of 30 mph. <br /> <br />Table 11: 85th Percentile Speed (in miles per hour) <br />Segment <br />Speed <br />Limit <br />(mph) <br />85th Percentile Speed <br />Towards I-280 Towards Downtown <br />Pre- <br />Pilot <br />Post- <br />Pilot <br />Absolute <br />Change <br />Percent <br />Change <br />Pre- <br />Pilot <br />Post- <br />Pilot <br />Absolute <br />Change <br />Percent <br />Change <br />Farm Hill <br />Boulevard: <br />Eden Bower <br />Ln-Lonesome <br />Pine Rd <br />35 45.9 42.7 -3.2 -7% 47.5 44.1 -3.4 -7% <br />Farm Hill <br />Boulevard: <br />McGarvey Ave- <br />Jefferson Ave <br />35 38.7 35 -3.7 -10% 37 32.4 -4.6 -12% <br />Jefferson: <br />Highland Ave <br />to Alameda de <br />las Pulgas <br />30 36.2 33.3 -2.8 -8% 36.4 33 -3.4 -9% <br />Source: Quality Traffic Data (May 26‐28, 2015 and May 31-June 2, 2016).
