Going towards I‐280, the percent of vehicles <br />exceeding the speed limit decreased from 49 percent to 18 percent. There was a similar trend going <br />towards downtown, with the percent of vehicles exceeding the speed limit decreasing from 32 percent <br />to 7 percent. <br /> <br />On Jefferson Avenue, between Highland Avenue to Alameda de las Pulgas, high percentages of <br />vehicles traveled above the speed limit before the start of the pilot – 72 percent towards I‐280 and 68 <br />percent towards downtown. After the pilot, the percentage of speeding decreased by 29 percent going <br />towards I-280 and 22 percent going towards downtown. <br /> <br />These results are consistent with the roadway improvements implemented. Vehicle speeds in a single <br />lane are set by the speed of the prudent driver. Narrower lanes force drivers to reduce travel speeds to <br />stay within the lane markings, thereby reducing travel speeds. <br /> <br />Percent of Vehicles Traveling more than 10 mph over the Speed Limit <br /> <br />Top‐end speeding is the percent of drivers traveling more than 10 miles per hour over the posted speed <br />limit. The speed limit on Jefferson Avenue is 30 miles per hour and on Farm Hill Boulevard it is 35 miles <br />per hour. <br /> <br />Table 14 shows the comparison of the percent of vehicles traveling 10 or more miles per hour between <br />the Pre-Pilot and Post-Pilot. Prior to the pilot project, between Eden Bower Lane and Lonesome Pine <br />Road, 21 percent of drivers in the westbound (going uphill towards I‐280) direction and 32 percent in <br />the eastbound (going downhill towards downtown) direction exceeded the speed limit by at least 10 <br />mph. After the pilot, these numbers decreased by 13 percent in the westbound direction and by 17 <br />percent in the eastbound direction. The other segments of Farm Hill Boulevard slightly decreased in <br />the share of vehicles exceeding the speed limit by greater than 10 mph. <br />8.A. - Page 28
