Mr. Dan Clumpner -6- December 7,2004 . TRAFFIC . FORECASTS Trip Generation Trip generation for all uses within the proposed development was developed based on data presented in the Institute of Transportation Engineers' Trip Generation, Seventh Edition, 2003. Trips resulting from this process. are gross trips. Given the mixed..,use characteristics ofthe proposed development, wnichincludes retail and service uses, we expect that a portion of the trips generated by these uses will occur within the site. Based on experience on similar projects, we expect that five percent of the gross total trips generated by the proposed development will be internal trips. Net trips for the proposed development were estimated by applying this five percent reduction to gross trips. The net total trips for the retail uses can be classified into the following three trip types: . New Trips ~ Tbps solely to and from the subject development. . Pass-By Trips- Existing "through" trips on Main Street that will include a stop at the subject development in future. . Diverted Trips - Existing "through" trips on TH 169 that will include a stop at the subject development in future. . Based on data published by the ITE and existing traffic volumes on TH 169 and Main Street, about 50 percent of the net total trips for the supermarket and pharmacy willbe ne~ trips, 30 percent will be diverted trips, and the remaining 20 percent will be passby trips. For the coffee shop, about 30 percent ofthe net total trips will be new trips, 60 percent will be diverted trips, and the remaining 10 percent will be passby trips. For the retail space, about 40 percent of the net total trips will be new trips, 50 percent will be diverted trips, and the remaining 10 percent will be passby trips. The townhouse land use was assumed to consist of all new trips. Table I shows oUr trip generation estimates for the a.m. and the p.m. peak hours on a typical weekday. Comparison of the current trip generation to the previous plan presented in our May 18, 2004 report indicates a decrease in the number oftrips generated in both peak hours with the current plan. .
