ROSEDALE MARKETPLACE TRAFFIC STUDY DECEMBER, 1988 INTRODUCTION This memorandum summarizes the results of a traffic study for the proposed Rosedale Marketplace Shopping Center in Roseville, Minnesota. The shopping center will be located in the southwest quadrant of the intersection of County Road B2 (C.S.A.H. 78) and Fairview Avenue (C.S.A.H. 48), west of the Rosedale Shopping Center (see Figure 1 - Location Map). The proposed shopping center will contain approximately 172,100 square feet of leasable retail space and a sit-down restaurant containing a total of 6,000 square feet (see Figure 2 - Site Layout). The remainder of this memorandum contains a summary of findings, recommendations and coneli.sions. TRIP GENERATION AND TRAFFIC ASSIGNMENT 1987 trip generation rates obtained in the Fourth Edition of the Institute of Transportation Engineers' 'rip Generation Manual were used to estimate the amount of traffic expected to be attracted to this shopping center. on a -.!y basis this shopping center will attract an estimated 100575 vehicle trips. In the PM peak hour the expected trip generation .for the center is 820 trips (400 in and 420 out). During the peak hour, tl.e restaurant should attract 270 trips (110 in and 160 out). For purposes of analysis, it is important to understand that standard trip generation rate aver -estivate the total traffic added by this development to .he roaadu"y system. It has beep; estimated that about 5 percent of the trip, would be internal to the shopping center. Up to 25 percent of the trips attracted to the center would be trips. "intercepted" from the surrounding a ondw,--ty system, and not be now trips added to roadways such as Fairview Avenue and County Road B2. They direction of approach (trip distribution) f -. the proposed center was estimated based on the existing traffic patterns to the Rosedale Shopping Center area and the projected traffic patterns for the Rosedale expansion currently being planried. The expected trip distribution during the PM peak hour- is shown in Table 1. 1
