. The inplace intersection of Snelling Avenue and County Road B is currently operating at Level of Service (LOS) "F" in the PM peak hour. This is characterizedby long queues for the Snelling mainline, the County Road B through movements and for several of the turn movements at the intersections. On some signal cycles, the queues do not clear within that cycle. At the present time Mn/DOT has plans to upgrade this intersection, when funding is available, to add an additional north-south through lane in each direction. The addition of a third through lane is the most beneficialtraffic enhancement that could be made to improve the service level at this intersection. • The unsignalized intersection 350 feet east of Snelling that serves all-way movements to both Target and the HarMar mall operates at LOS "F" in the PM peak hour. Vehicles leaving Target or HarMar and wishing to turn left or cross County Road B have severe difficulty making these movements and experience significant delay while waiting for a gap in traffic. • All of the other unsignalized intersections in the study area exhibit acceptable levels of service in the peak hours under existing conditions. CHANGES TO ROADWAY NETWORK The study area will undergo many roadway changes to support the developmentofthenew SuperTarget. A median is planned to be constructed on County Road B between Snelling Avenue and State Farm Road. This median will close off existing crossings, thereby reducing traffic conflicts, improving traffic safety and improving traffic operations. The praposed median closure will also shift some traffic movements to other locations. Traffic that can no longer cross or turn left ontoloff of County Road B will be expected to shift to the inplace County Road B/State Farm Road intersection. This intersection is signalized with protected pernnissive ]�f� turn phases along County Road B. Turning and crossing traffic will increase at this intersection due to the shifted traffic and the additional traffic generated by the redevelopment. TRAFFIC FORECAST METHODOLOGY AND ASSIGNMENT The traffic forecasts for the redevelopment were produced in a four-part process. 'I'he first step was to adjust the current counts to reflect the proposed roadway and access modifi�ations. The second step was to determine the incrementof new traffic expected to be generafied.by the change from the existing Target to the new SuperTarget, together with the opening of the new restaurant and retail uses. The next step in the process was to determine the direction of approach for new trips, and, finally, the new traffic was assigned to the roadway network to develop the total volumes to be used for the site analysis. Adjusted Traffic Volumes The December 2003, traffic counts were adjusted to account for the modified roadway geometry. This was accomplished by reassigning any current left turn or crossing through movements to the location it would shift to when the median is fully extended from Snelling to State Farm Road. The results of this volume adjustment for the AM and PM turning movement counts are shown on Appendix Figure A-2. These adjusted volumes become the base volumes to be �used in the determination of the fully-developed (with SuperTarget) volumes. The fully-developed volumes Page 2
