See Figures 3 and 4 for location of primary access points to site. <br />Future Forecasts <br />Forecast horizon years of 2007 and 2025 were selected for evaluation. These two planning <br />horizon years are consistent with the forecast years for the Downtown Eugene Federal <br />Courthouse Transportation Study. I ~ The volumes forecasted in the Downtown Eugene Federal <br />Courthouse Transportation Study were used as a base for "no-build" alternatives for planning <br />horizon years. Trips generated by the proposed site relocation were then overlaid on top of these <br />no-build conditions with redistributing some trips due to access management and new circulation <br />access to forecast a "build" condition for analysis. <br />Trip Generation <br />Trip generation for the proposed project was estimated using the ITE Trip Generation Manual <br />(7`h Edition). Trip generation for a hospital land use can be done using either number of beds or <br />square footage. The trip estimates using square footage is typically higher than the trips <br />estimated using number of beds. Calculations for trip generation was done using both the fitted <br />curved equation of the average rate to generate trips was selected based on the number of similar <br />studies using similar square footage. Table 3 summarizes the trip generation selected for this <br />analysis. <br />Table 3 <br />Trip Generation for Hospital Use <br /> 2007 (250K sq. ft.) 2025 (470K sq. ft.) <br />Time Period In Trips Out Trips Total In Trips Out Trips Total <br />Daily Trips 2,200 2,200 4,400 4,130 4,130 8,260 <br />AM Peak Hour Trips 235 135 370 435 255 690 <br />PM Peak Hour Trips 155 250 405 290 470 760 <br />In 2007, The AM peak hour would have approximately 370 trips and the PM peak hour would <br />have approximately 405 trips. By 2025 the trip generation would increase with the expansion of <br />a~; <br />square footage to generate approximately 690 AM peak hour trips and 760 PM peak hour trips. <br />Trip Distribution <br />Trips to and from a hospital are typically made up of multiple types of users ranging from <br />employees to patients/visitors. Also the trips to/from a hospital occur at multiple times of the <br />day due to employee shift changes, arrival of patients/visitors and deliveries of goods/services. <br />This usually has an affect on trip distribution for a hospital site. For this preliminary analysis, <br />trip distribution was based on input from the Lane Council of Governments regional travel <br />demand models (2000 and 2025). These models were used to help estimate the trip distribution <br />from the project site to surrounding areas. There were no major differences between the trip <br />distribution calculated for the 2007 or 2025 planning horizon years. Figure 5 shows the assumed <br />trip distribution for the study area. Once the trip distribution had been calculated, trips were <br />assigned based on the trip generation and the trip distribution. <br />', i ~ Similar to the Draft Downtown Eugene Federal Courthouse Transportation Impact Analysis, prepared by DKS <br />Associates, Apri12004. <br />j Eugene Triad Hospital Relocation Analysis Page 9 of 17 <br />~, <br />
