Sub-problem 3c - Page 8 of 9

Sub-problem 3c: The Southwestern Quadrant

We will look at both conditions. We’ll begin by assuming that the weaving section starts where the three-lane section begins, which is the shortest it can be at 1,055 feet. We will also assume it starts at the initial merge, making it 1,850 feet.

Exhibit 4-62. LOS Variance with Weave Length

1,055 47.94 F Unconstrained
1,850 43.51 F Unconstrained
2,000 42.29 E Unconstrained

The results of these two analyses are shown in Exhibit 4-62. We see that both analyses predict the weaving section is at LOS F. This is because of the high weaving volumes in combination with the short weaving distances. As the weave length increases, the densities decrease, and the LOS nominally improves, although it stays at LOS F. To improve the LOS, we would have to increase the weaving length to something greater than the maximum presently allowed. As Exhibit 4-62 shows, at 2,000 feet, the LOS becomes E with a density of 42.29 pcpmpl.
