design options, along with impacts associated with various alternatives. This study recommended an open air bridge with a helix approach ramp located just south of Riverdale Drive. A preferred bridge concept was also identified, with a prefabricated steel truss including dual modified bowstring arches. 3.Future Roadway System This section addresses future roadway improvement needs and roadway design guidelines. 3.1.Roadway Capacity Traffic Forecasting To determine future roadway capacity needs, year 2040 traffic forecasts were prepared using the Metropolitan Council travel demand model. The 2040 projections were compared against the assumed 2040 roadway network to see where roadway segment capacity deficiencies may result. The 2040 roadway network assumed for this analysis is the same as the current roadway network, as the City and County Capital Improvement Plans (CIPs) do not include any projects that add significant capacity to the roadway network. While the travel demand model is a valuable tool for identifying future traffic based on the proposed land use impacts, it is not meant for use in detailed traffic operations studies. For a more accurate representation of the transportation impacts from specific developments, detailed traffic studies should be conducted to determine the operational impacts on adjacent roadways and intersections. A central concept of travel demand forecasting is the use of Transportation Analysis Zones (TAZs). Each forecast study area, in this case, the City of Ramsey, is divided into a series of TAZs. Each TAZ has population, employment, and household data that is used by the model to assign trips to the various network roadways. displays Metropolitan Council TAZs Figure 5 within Ramsey. The results of the Ramsey modeling process are summarized in , which displays Figure 6 Metropolitan Council 2040 projected average daily traffic volumes compared to the existing (20122015) traffic volumes. andprovide a summary of existing and forecasted demographic growth by TAZ Tables 5a 5b for Ramsey through the year 2040. The Ramsey population is forecasted to reach slightly over X,XXX by the year 2040, with households and employment increasing by XXX and XXX respectively. Allocated demographic growth and associated land use was generally located in the XXXXXX and XXXXXXX portions of the community. High density residential was also generally allocated to the southern portion of the city, with commercial and multi-optional development areas also generally identified within the southern portion of the city, consistent with the Center of Ramsey (COR) land use plan. For more information about the demographic allocation and associated land use forecast, please refer to the Ramsey Land Use Plan in Chapter X of the Ramsey Comprehensive Plan.
