Robert Cunningham -10- January 27, 1998 TRAFFIC ANALYSIS The analysis results and needed improvements (if any) are presented next for the critical issu�s addressed in this study;: The issues examined are listed as follows: � Effects on neighborhood streets • Effects on emergency vehicle services • Effects on school bus services • Effects at key roadway locations • Main Access on County Road I - Operation of T.H. 10 at County Road I • Spacing of Walgreens Access on County Road I • Operation and Spacing of Right in / Right out access on T.H. 10 • Traffic operations within the site The Highway Capacity Software program was used to analyze some capacity aspects of the various intersections. Level of service A refers to an operational condition with little delay where as level of service F refers to a condition where long delays can be expected. Intersections and roadways are designed to provide a level of service D or better. A conceptual site plan for the development is presented in Figure 4. The figure approximates what the development will look like and how it will interact with the adjacent roadway system. Effects of the Development On Neighborhood Streets • Daily Volume Analysis As described in the previous section, the 330 daily trips that are redistributed through the neighborhood will increase the volumes along Greenwood Drive to 664 vehicles per day. On a daily basis, the Walgreens development will generate 135 trips from the neighborhood to the north. This additional Walgreens development traffic will increase the daily volume on Greenwood Drive by about 50 trips to 714. The Metropolitan Council has established a threshold volume of 1,000 vehicle trips per day for roads classified as local streets. The resulting volumes on Greenwood Dcive will still be well below this volume limit. Thus, the Walgreens development is not expected to cause any significant problems along Greenwood Drive. For Sunnyside Road, the increase that can be expected due to the closure of Eastwood Drive is three vehicles for a total of 195 vehicles per day. The increase expected as a result of the Walgreens development is 15 trips. The total volume increase on Sunnyside Road would therefore be 18 vehicles for a total of 210 daily vehicle trips. The remaining trips from both the closure of Eastwood Drive and the Walgreens development are distributed to other routes such as T.H. 10 and Long Lake Road.
