The coffee shop with a drive-thru <br />data is found in the Newsletter of the North Central Section of the Institute of Traffic Engineers (Volume <br />22, Nuniber 4, Fall 2005), which details a trip generation study of local coffee shops with and without a <br />drive-thru. <br />Table 1 <br />Existing Starbucks with �ri���Thrs�- <br />Weekda AM I Weekday PM <br />Enter Exit Enter � Exit <br />F tD� i t�� i 48 I 77 � <br />223 125 <br />1.

Per NCITE data. <br />Comparison of the NCITE trip generation data for a drive-thru coffee shop with the RLK Incorporated <br />observed counts for the existing drive-thru Starbucks indicate compatible data. The RLK. weekday AM <br />counts are slightly lower than the NCITE data, while the RLK weekday PM counts are somewhat higher <br />than the NCITE data. NCITE total daily traffic data, which should be similar for the existing drive-thru <br />Starbucks, indicates that the weekday average daily traffic for this land use is 1,001 vehicle trips. <br />Vehicle Stackin� <br />➢ It was observed the existing drive-thru lane caa7 accommodate approximately 8 vehicles without <br />extending into the West Perimeter RoadlStart��zcks Access intersection. <br />➢ During the AM peak hour, the available storage length of the drive-thru lane was exceeded <br />approximately 10% of the time and a maximum of 11 vehicle were observed to be stacked and <br />the queue extended into the West Perimeter RoadlStarbucks Access intersection. <br />➢ During the PM peak hour, the available storage length of the drive-thru lat7e was able to <br />accommodate stacked vehicles. A maximum of 6 vehicles were observed to be stacked during <br />the PM peak hour. <br />Drive-Thru Service Duration <br />➢ During the AM peak hour, the duration of the average drive-thru service time was approximately <br />3:27 with a maximum observed time of 5:11. <br />ftl,iC Incorparated Page 2 of 3 Project Name <br />G1KimcaReaity�n;..�r�.'r'�s's- RT.
