SSTS S' TRAFFIC SOLUTIONS The counts indicate there is a strong directional peaking during the AM peak, with approximately 2/3 of the traffic destined to the east toward Minneapolis and St Paul. Also, as shown on the Figure TH 10 is a divided four -lane road with turn lanes and Lowell Avenue NW is a two-lane road. The Lowell Avenue NW roadway width at the intersection with TH 10 measures 36 feet, which is enough for northbound traffic to form two lines one for left turns and one for right turns, however, during the AM peak there were no left turns counted. Trip Generation and Distribution The trip generation for the proposed coffee shack discussed in the introduction has been estimated based on the methodology described by the Institute of Transportation Engineers (ITE) in Trip Generation, I I" Edition, ITE's Trip Generation Handbook, 3rd Edition, as well as on data provided by Caribou. The ITE land use code coinciding with the development is Code 938 for Coffee Shop with Drive-Thru Window No Indoor Seating. The ITE data suggests the development will generate approximately 40 trips during the heaviest AM Peak, however, the data supplied by Caribou from similar site in the Twin Cities suggests the site could generate up to 130 trips during the heaviest AM Peak trips. Table 1 summarizes the trip generation for this type of development, utilizing the Caribou data. Table 1 Trip Generation Forecast Land Use ID!rive-thru AM Peak Hour PM Peak Hour Daily Trips Enter Exit Enter Exit Coffee No Seating 65 Trips 65 Trips 22 Trips 22 Trips 682 Trips NET TOTAL 130 Trips 44 Trips 682 Trips As shown in Table 2, the site will generate 65 entering and 65 exiting trips during the critical morning traffic peak hour. The ITE Trip Generation Handbook, 3rd Edition, outlines a procedure to account for pass -by trips. Pass -by trips are those trips already using the adjacent roadway that enter the site as an intermediate stop on their way to another destination. The pass -by trips are not generated by the land use under study, and thus, are not new trips added to the network but are trips using the site accesses. The coffee shop use is estimated to generate 89 percent pass -by traffic. In this case these trips were taken from the through traffic on TH 10 and assigned to Lowell Avenue NW. The distribution of site traffic in this study assumes all traffic will originate from TH 10 and return to TH 10. This is conservative as it is likely some traffic on Main Street would also stop at the site. Also, it was assumed that only traffic that is destined to the east will visit the site, which places all of the site traffic on Lowell Avenue NW. Westbound traffic using the site would turn left from TH 10 to get to the site, but would use the traffic light at Jackson NW to head west. Again, this is conservative as it assumes all site traffic uses the TH 10 and Lowell Avenue NW intersection. The Figure below shows the traffic volumes with the Build out of the coffee shop. 2 I P a g e Caribou Coffee, Elk River, MN
