The single lane of vehicles would have less frequent gaps for side street vehicles to turn into. <br /> <br />Measurement: To evaluate how long drivers have to wait to turn left, the traffic consultants videotaped <br />the side streets of Lonesome Pine Road and Highland Avenue during the morning peak period (7:00 <br />AM – 9:00 AM). The number of vehicles waiting to turn left was counted at five-minute intervals and <br />divided by 12 to estimate their wait times. <br />Outcome: Table 10 summarizes the results. It should be noted that there was a small sample size for <br />this performance measure, as denoted by the number of vehicles counted (n). At both locations there <br />was a 48 to 67 percent reduction in the wait time for vehicles to make a left turn from the side street <br />during the morning peak hour. At Lonesome Pine Road, the typical wait times were less than a minute <br />and the overall reduction was small as an absolute number. At Highland Avenue, the wait times were <br />estimated at 4 minutes before the pilot and reduced to 2.1 minutes after the pilot. The decrease in <br />average delay for vehicles on the side-street making a left turn can be attributed to the decrease in the <br />number of lanes crossed to make the left turn, the storage space in the two-way left-turn lane, and the <br />reduction in travel speed along the main street. <br />Table 10: Average Delay for Vehicles Making a Left Turn, AM Peak Period (Seconds) <br />Location Pre-Pilot Post-Pilot Absolute <br />Change <br />Percent <br />Change <br />Lonesome Pine Road 54 <br />(n=11) <br />20 <br />(n=5) -34 -63% <br />Highland Avenue 240 <br />(n=48) <br />125 <br />(n=40) -115 -48% <br />Source: Quality Traffic Data (May 27, 2015 and June 2, 2016). <br />n = number of vehicles trying to turn left, counted at five-minute intervals <br /> <br />8.A. - Page 24
