Using existing mming movements as a base, the model outpu. t was broken out into '-;'2~"~ turning movements for the five intersections included in the model. They are as , follows: · Cleveland Ave. and County Road C · Cleveland Ave. and I 35W ramps north of County Road C · Cleveland Ave. and County Road C2 · Cleveland Ave. and County Road D · West I 35W ramps and County Road D · East I 35W ramps and County Road D . Comparison of model results to historical growth . Historical ADT available for road segments adjacent to the study area intersections was examined and it was found that the overall average annual percent growth in traffic was approximately 2% for the study area. . The existing turning movements for the study area intersections described above were factored up at a rate of 2% per year for four years to reach 2001 forecast conditions. . The 2001 growth factor forecast turning movements were compared to the 2001 model-based forecast turning movements as a consistency check. While they were roughly similar, the growth factor forecasts were higher overall. Therefore, the growth factor foreeasts were used as the 2001 background forecasts in order to remain conservative (see figure called ''2001 Background Traffic - PM Peak Hour). . Development of Site Generated Traffic Forecast . Estimation of PM peak hour trip generation . Each site lot was broken down into the following land use categories (see Table called "Estimated Trip Generation on Site") based on discussion with Ryan Companies: - General Office · High Turnover Sitdown Restaurant - Showroom/Warehouse · Business Hotel . Given thaI site plans often are subject to change, the proposed land uses were broken down by type versus by individual Jot . Trips were generated from each land use for the PM peak hour using the JTE Trip Generation Manual, 5th Edition (1991) and the Februarv 1995 Update to the 5th Edition (1995). 2
