~=~ Kimley-Horn and Associates, Inc. Mr. Bill Burgess, August 26, 2002, Page 3 Data was collected on typical weekdays (Tuesday, Wednesday, or Thursday) for use in the calculation of the trip generation variable. Trip generation counts were conducted manually at all of the outparcel gas stations for the twenty Wal*Mart Supercenter study sites. Traffic volumes entering and exiting the gas station were counted from 4:00 p.m. to 6:00 p.m. and recorded in IS-minute intervals. Table I contains a summary of the p.m. peak hour trip generation volume information obtained at each study site. Trip type information was collected at each study site by interviewing gas station patrons. For purposes of uniformity, trip type data was collected at each study site during the same day as the p.m. peak hour trip generation data was collected. An average of the percentages of new, internal capture, pass-by, and diverted trips at each site was obtained to calculate the most accurate trip type information. Traffic questionnaires were used to identify the origins and destinations of trips to the outparcel gas stations at each of the Wal*Mart Supercenter study sites for the purposes of identifying the trip type (new, internal capture, diverted, and pass-by) as a percentage of the total trips to the gas station site. For each gas station study site, the percentage of new, internal capture, pass-by, and diverted trips was determined. The overall percentage of trip types for the gas station sites was determined by taking the weighted average of the trip type percentages determined by each of the twenty study sites. Table 2 summarizes the results of the gas station trip type study. Trip Characteristic Results This trip characteristics study examined the trip generation rate as well as the percentage of new, internal capture, pass-by, and diverted trips at twenty gas stations at existing Wal*Mart Supercenters nationwide during the p.m. peak hour. Based upon the results of this study, the following trip characteristics were determined to be representative of Wal*Mart Supercenter gas station sites during the p.m. peak hour (4:00 p.m. to 6:00 p.m.): · Trip Generation Rate = 15.6 trip ends I vehicle fueling position · Percent New Trips = 8% · Percent Internal Capture Trips = 56% · Percent Pass-By Trips = 24% · Percent Diverted Trips = 12% Analvsis for City of Zephvrhills A transportation impact fee analysis was conducted for the Zephyrhills Murphy Oil gas station outparcel using the results of the nationwide gas station trip characteristic study and the site specific parameters of the proposed Zephyrhills Murphy Oil. While the data for the nationwide study was collected during the p.m. peak hour (4:00 p.m. to 6:00 p.m.), a p.m. peak hour to daily ratio was determined using factors contained in the Institute of Transportation Engineers (ITE) Trip Generation, 6th Edition, in order to correlate the results to the City's trip generation variable which is expressed as a daily trip rate.
