MnDOT Contract No. 1028386 Work Order No. 1 Exhibit B Detailed Scope of Work and Deliverables 14 3. 165 th Avenue and TH 10 4. Future Twin Lakes Road/ Kelley Parkway and TH 10 5. 171 st Avenue and TH 10 6. 171 st Avenue and Twin Lakes Parkway 7. Alpine Drive and CSAH 83 (Armstrong Boulevard) 8. CSAH 83 (Baugh Street) and AC CSAH 22/CR 64 (181 st Avenue) 9. Sherburne CSAH 12 (181 st Avenue) and Twin Lakes Road/CSAH 13 Results of the analysis will identify level of service, delay, and queuing information for each intersection. As the TH 10 corridor continues to transition to a grade-separated freeway type facility, it will become more difficult for motorists to access TH 10 from unsignalized at-grade intersections. To address this issue, we will complete a gap analysis for each side-street stop intersection using information from the site observation along with the existing traffic volumes. Traffic Forecasting The consultant teams travel demand forecasters will produce forecasts needed to evaluate the TH 10 corridor. The consultant team will build off forecasting efforts from the 169 Redefine and TH 10 Rum River projects and incorporate any additional information that has been developed from the Twin Lakes Road/Kelley Parkway project. The basis for the travel demand modeling will be the current Anoka County Travel Demand Model, which has detailed local roadway network and land use detail in this area. The model will be reviewed for network accuracy and validated prior to completing future year forecasts. A list of regional and significant local projects in the study area will be developed for use in the no build condition. Improvements will be confirmed based on the State Transportation Improvement Program (STIP), Highway Infrastructure Program (HIP), and local Capital Improvement Program (CIP). Future year land use assumptions will be consistent with the 169 Redefine project. The network and land use assumptions will be verified with the Local Government/Agency and State prior to developing forecasts. Since the Travel Demand Model is based off year 2040 land use assumptions, year 2040 traffic forecasts will initially be developed. Based off these 2040 forecasts and existing traffic volumes, the consultant team will work with the Local Government/Agency to understand near and long-term development projections for the area. Using this information, the consultant team will develop traffic forecasts for year 2025, 2035, and 2045. Forecasts will be checked against historical rates using traffic data from the automatic traffic recorder (ATR) station 352 that is located along TH 10 at the truck weigh station east of the Sherburne/ Anoka County line. The consultant team will specifically focus on the timing of the planned freeway conversions of TH 10 and TH 169 in the area. These projects will likely influence travel volumes and patterns more than the planned development in the area. A Travel Demand Forecast Technical memo will document land use and roadway network assumptions, forecast methodology, validation process, model adjustment and future year results. This draft memo will be reviewed and approved by the City of Elk River and MnDOT staff before the traffic operations analysis proceed. Future Year Traffic Analysis Year 2025, 2035 and 2045 Operations Analysis Year 2025, 2035, and 2045 conditions analysis will be performed again using VISSIM at each of the previous study intersections to determine any future deficiencies that may require mitigation. This is considered a no build condition assessment that will account for programmed improvements in the study area. Based on the results of the existing, year 2025, 2035, and 2045 analysis intersections or corridor segments that experience operational issues under existing and future conditions will be identified and near-, mid-, and long-term improvements will be recommended.
