The second option, recommended for developed and rural communities, is a <br />trend analysis (applying a historical growth factor to cnrrent volumes). Based on our understanding as <br />to the level of analysis the City is seeking we propose utilizing both these forecasting options. The <br />Met Councils Regional Traffic Model will be utilized to forecast traffic volumes on only arterial <br />roadways and above. No alterations regarding existing, planned, or future land uSeS in the City of <br />Arden Hills and/or Ramsey County will be made to the existing model. Traffic forecasts on MSA <br />routes will be calculated using the trend analysis option where current daily traffic counts and an <br />agreed upon historic growth factor will be applied to obtain the 2030 forecast volumes. <br /> <br />Forecasts will not be completed for the local (City) system of collector roadways. The Transportation <br />Element will include a figure illustrating the existing and forecast traffic volumes and a narrative will <br />be provided explaining how the two options of traffic forecasting were utilized. <br /> <br />4. Capacitv Assessment - SEH will assess and document the existing systems capacity (MSA roadways <br />and above) using volume/capacity (V/e) ratios produced by the 2030 traffic forecasts. No intersection <br />analysis or congestion solution recommendations will be provided. <br /> <br />5. Safety Assessment - SEH will provide a summary and graphically illustrate crash information <br />obtained through the use of the Minnesota Crash Mapping Analysis Tool (MnCMA T) database. The <br />documentation will summarize the inventory of historical problem areas and discuss general <br />improvement strategies such as access management, intersection changes and signal timing. This task <br />will not identify the degree of a safety problem and will not provide recommended solutions at <br />specific locations. <br /> <br />6. Review and Refine the Functional Classification Svstem - The latest Metropolitan Council functional <br />classification network will be reviewed against the system established in the City's 1998 <br />Comprehensive Plan to determine if there are inconsistencies and the rationale for the inconsistencies. <br />It is assumed that a network consistent with the Metropolitan Council's system will be defined and <br />mapped. The map will include the following: <br /> <br />a. Existing number oflanes and future number oflanes (see Task 4 above for capacity assessment) <br />b. Current daily traffic counts (from existing Mn/DOT data) <br />c. Forecast 2030 traffic volumes (see Task 3 above for forecast methodology) <br /> <br />7. Access Management Guidelines - The transportation element will address the spacing between public <br />street and/or private access points on the roadway system based upon the functional classification of <br />the roadway. <br /> <br />8. Transit Assessment - SEH will identify, map, and summarize Arden Hills transit service areas and <br />facilities. <br /> <br />a. The map for inclusion in the Transportation Element will include: <br />existing and planned transit corridors <br />existing and programmed park-and-ride facilities <br />potential future park-and-ride facility sites <br />existing and planned passenger facilities, such as transit centers and stations <br />transit support facilities, such as maintenance facilities and garages <br />
