L- sed traffic model to estimate 2001 Background T raHic <br /> <br />- Interpolated 2001 daily trip generation for entire city using 1990 base <br />year and 2010 forecast year daily trip generation. <br /> <br />- Further refined daily trip generation in Rose\'ilJe Traffjc .\lodeJ to <br />incJude land use changes expected to occur adjacent to Centre Poi;,te <br />(1 able n <br /> <br />- Distributed and .Assigned daily trips in 2001 to 2001 Rose\'i]]e m\)l~C': <br />network. <br /> <br />- Adjusted assigned traffic by' difference betl\'een 1990 cicily tr2.iiic c~lun:s <br />and 1990 daily model assignments. , <br /> <br />- .\1ultiplied daily 2001 model assignments by 8.40", ,,\'hich is the peak <br />hourly percentage of daily traffic (time of day is 4-5 P.\1), Source oi data <br />is ATR station #430 on County Road C just west of Prior A\"enue, Data <br />year is 1994 which is latest available from '\In/DOT. <br /> <br />.. Csing existing turning mo"ements as a base, the model output \\'as <br />broken out into turning movements for the five intersections incJuded m <br />the model. Thev are as follows: <br /> <br />- Cle,"eland Avenue and County Road C <br />- Cleveland _A.\'enue and 1-35W ramps north of County Road C <br />- Cleveland Avenue and County Road C2 <br />- Cleveland A "enue and County Road D <br />- West 1-35\\1 ramps and County Road D <br />- East 1-35\\1 ramps and County Road D <br /> <br />The resulting background forecasts from the model are included in the <br />Appendix. <br /> <br />.. Comparison of model results to historical growth <br /> <br />- Historical ADT available for road segments adjacent to the study area <br />intersections was examined and it was found that the overall average <br />annual percent growth in traffic was approximately 2% for the study <br />area. <br />
