NEED FOR THE PROPOSED REVISIONS <br /> A. Traffic Volumes <br /> Projected traffic volumes alon g Project I-303 for the year 1990 <br /> range from 41,900 vehicles per day (vpd) east of Burlington to 50,700 vpd <br /> west of Burlington. Projected traffic volumes for the year 2010 range <br /> from 47,900 vpd near Greensboro to 100,100 vpd west of Burlington. The <br /> 2010 projections are based upon the I-85 Greensboro bypass (TIP Project <br /> No. 1-2402) being completed and in operation. As noted in Section I.B.1. <br /> of this report, Project I-2402 is scheduled to be let to contract in <br /> Fiscal Year 1996. <br /> Projected traffic volumes along Project I-304 range from 34,900 vpd. <br /> east of Efland to 41,900 vpd east of Burlington. Projected traffic <br /> volumes for the year 2010 at the above locations are 71,500 vpd and <br /> 84,100 vpd, respectively. <br /> - B. Capacity Analyses <br /> 1. Six-Lane Versus Eight-Lane Widening <br /> Capacity analyses were performed to compare the level-of- <br /> service at which I-85 would operate assuming both six-lane and <br /> eight-lane widening. Six-lane widening was recommended in the FONSI <br /> for Projects 1-303 and 304; however, eight-lane widening is now <br /> proposed. The results of these analyses for the years 1990 and 2010 <br /> are shown in Table 2. <br /> Table 2 <br /> Levels-of-Service <br /> 1990 - 2010 <br /> • <br /> Project 6 lanes 8 lanes 6 lanes 8 lanes <br /> 1-303 D-E C .
