Mr. John Weicht -4- . May 11, 1994 Table 1 shows the trip generation rates and the corresponding number of trips. TABLE 1 III P.M.

The percentages were developed based on observations of traffic movements in and out of the existing retail uses. The bottom half of Figure 2 shows the expected trip • distribution percentages for the passby trips. These percentages are based on current directional traffic volumes on T.H. 169. Utilizing the trip generation and trip distribution previously discussed, trips to and from the development were assigned to the roadway system under the two roadway alternatives described earlier. V.1 m- ' . •I R-m."n _ . . -••- _ • R'• I. is • - •n . ,• As shown in the top half of Figure 3, traffic volumes increase slightly on all approach legs of the T.H. 169/Main St. intersection without the right turn in/out access on T.H. 169 at Carson St. The additional traffic equates to a 5.8 percent increase in traffic entering the intersection. This is a small increase and is not expected to cause any significant impact on traffic operations at this intersection. The bottom half of Figure 3 shows the existing and post-development traffic volumes at the Main St./Carson St. intersection without the right turn in/out access on T.H. 169 at Carson St. As shown in the figure, traffic volumes increase for the movements to and from Carson St., as expected, and remain the same on Main St. The increases on Carson St. will probably cause additional delays to vehicles using this street, especially to those vehicles exiting the area on Carson St. plumes if Carson St. is Extended to Provide Right Tprn In and Out Accesion T,H. 160 From the trip assignment process, it was estimated that 37 vehicles would enter and 61 vehicles would exit Carson St. via the right turn access on T.H. 169 during the p.m. peak hour. Of the 37 vehicles that enter, it was estimated that only 9 vehicles would • use Carson St. as a through route. The small amount of through traffic can be attributed to the attractiveness of the channelized right turn lane at the T.H. I69/Main St. intersection. The remaining 28 vehicles would use Carson St. to access new or existing businesses in the development.
