! I I ! Future Traffic Considerations Analysis was also completed for the intersections for a future year of 2016. It is anticipated that an additional 26 single-family housing units will be added to Kelly Acres and an additional 128 single-family housing units will be added to Rum River Prairie. The Kelly Acres units will be added adjacent to the initial development, while the Rum River Prairie units will be added to the west of Armstrong Boulevard. The trip generation table is presented in Table 2.

Background traffic was grown at the rate 2.5% per year. This growth is likely throughout the area within the next I0 years. The 2016 Baseline volumes are shown in Figure 4. All Development traffic was then added to the 2016 Baseline to come up with the Full Build Volumes as shown in Figure 5. Traffic Operations Analysis Analysis was completed for each of the scenarios for both the A.M. and P.M. peak hours. The analysis was performed using the methodology of the 2000 Highway Capacity Manual through SYNCHRO, a traffic analysis sol, are program by Trafficware. Results of the analysis are displayed as measures of effectiveness. Measures of effectiveness display quantitative information about the performance of an intersection or network of intersections. The pr/mary measures that are used in this study are level ofserv/ce and delay. Level of Service The operational analysis results are described as a Level of Service (LOS) ranging fi.om A to F and these letters serve to describe a range of operating conditions for different types of facilities. Levels of Service are calculated based on the 2000 Highway Capacity Manual, which defines the level of service, based on control delay. Control delay is the delay experienced by vehicles slowing down for a signal or stop sign, the wait time at the signal or stop sign, and the time for the vehicle to speed up and get through the signal or enter into the traffic stream. The average intersection control delay is a volume weighted ' average of all delay from all intersection approaches for signalized intersections. Level of Service D is commonly taken as an acceptable desi~ year LOS.
