This is considered to be a conservative <br />assumption, since residents could walk to and from the school to attend classes. <br />OFF -SITE TRAFFIC IMPACTS <br />The traffic impacts of the project were considered at the following intersec- <br />tions: <br />o Lexington Avenue/Grandview Avenue <br />o Lexington Avenue/Project Access Driveway <br />o Lexington Avenue/TH 36 Westbound Ramps <br />0 Lexington Avenue/TH 36 Eastbound Ramps <br />The critical period for the evaluation of traffic conditions is the PM peak <br />hour, typically occurring from 4:30 PM to 5:30 PM. Existing traffic counts <br />(October 1988) were conducted by BRW at each of the intersections listed above <br />during the PM peak hour. The traffic impacts of the project were evaluated by <br />adding existing traffic to traffic which would be generated at the project site. s <br />The determination of project traffic impacts included an assumption that traffic <br />e would be oriented as follows: <br />generated at the project sit <br />o 10 percent to/from Lexington Avenue north of Grandview 'F <br />0 40 percent to/from TH 36 east of Lexington <br />o 40 percent to/from TH 36 west of Lexington <br />36 <br />o 10 percent to/from Lexington south o <br />f TH <br />The operations of the signalized intersections at Lexington Avenue and the TH 36 <br />ramps were evaluated using the planning method for analysis of signalized inter- <br />sections from the 1985 Highway Capacity Manual?/. The table below summarizes <br />the impact of the project's traffic on these two intersections: <br />Intersection <br />% of Capacity Utilized <br />Existing Existing Plus Project <br />Lexington/TH 36 WB 63% 64% <br />Lexington/TH 36 EB 71% 74% <br />2/ Highway Capacity Manual, Transportation Research Board, 1985 <br />
