HIGHWAY 10 CORRIDOR STUDY - FINAL REPORT <br />Table 8. Benefit Cost Analysis — North Segment <br />1 Costs in 2022 dollars, low cost did not include local roadway connections. <br />Table 9.

Using the future traffic volumes with capacity calculation procedures discussed in the <br />Highway Capacity Manual, Figure26and Figure27were developed. These figures show the capacity <br />thresholds for signalized and grade -separated corridors. The black boxes around the capacity <br />thresholds show the range of peak hour traffic volumes the Highway 10 corridor is projected to <br />experience in the future. Based on the capacity thresholds shown in Figure26, Alternative 1 and <br />Alternative 2 are expected to exceed capacity on Highway 10. Based on the capacity thresholds <br />shown in Figure27, Alternative 3 is expected to be under capacity on Highway 10. <br />Figure 26.
