Brian Olson, P.E. - 6 - May 31, 2001 <br /> <br />Traffic Forecasts <br /> <br />For purposes of this study, the proposed development is expected to be constructed by year 2003. <br />Traffic forecasts were developed for the year 2004, one year after development. A three-percent <br />yearly growth rate was used to account for growth in background traffic volumes. <br /> <br />Trip generation estimates for daily and a.m./p.m, peak hours were calculated for the proposed <br />developments based on land use type and size, and trip generation formulas from the 1997 ITE <br />Trip Generation Reports. The trip generation results are displayed in Table 2. <br /> <br />Table 2 <br />Trip Generation Estimates <br /> <br />Land Use Land Use Size Daily A.M. Peak ,.. P.M.

Figure 4 displays the <br />directional distribution percentages for the residential development. The combination of <br />background traffic and trips generated by the proposed developments, is shown in Figure 5 for-the <br />year 2004 a.m. and p.m. peak hours. <br /> <br />Future Traffic Operations Analysis <br /> <br />To determine how well' the existing-roadway system will accommodate the proposed <br />developments, a traffic operations analysis was conducted for the a.m. and p.m. peak hours for <br />the year 2004. In addition to the key intersections previously listed, an operations analysis was <br />also conducted at the site access roadway and CSAH 5. <br /> <br />The signalized intersection of TH 47/CSAH 5 was analyzed, using Synchro. The unsignalized <br />intersections of CSAH 5/Dysprosium Street and CSAH 5/Site Access Roadway were analyzed <br />using the Highway Capacity Software. For purposes of this analysis, the geometrics shown in <br />Figure 5 were assumed for the CSAH 5/Site Access Roadway intersection, representing a worst- <br />case scenario. As shown in Table 3, the intersections of TH 47/CSAH 5 and <br /> <br /> <br />
