Exhibit ES18A: Impact of Reducing Baseline VMT Growth Assumptions on Average Annual Investment Requirements

Impact of Reducing Baseline VMT Growth Assumptions on Average Annual Investment Requirements (see description below)

Exhibit ES18A is a bar graph that shows the impact of reducing baseline vehicle miles traveled (VMT) growth assumptions on average annual investment requirements. The vertical axis has three bars-baseline, increased, and decreased-with two parts each. The horizontal axis measures billions of 2000 dollars from 0 to 180 in increments of $20 billion. In the first bar-where the baseline is 2.08 percent average annual investment requirement-the "cost to improve" is around $105 billion and the "cost to maintain" is around $78 billion. In the second bar-increased to 2.99 percent-the "cost to improve" is around $161 billion and the "cost to maintain" is around $115 billion. And in the third bar-decreased to 1.17 percent- the "cost to improve" is around $76 billion and the "cost to maintain" is around $52 billion.
