Exhibit ES16A: Projected Changes in 2020 Highway Condition and Performance Measures Compared to 2000 Levels at Different Possible Funding Levels

Exhibit ES16A is a chart that shows projected changes in 2020 highway condition and performance measures compared to 2000 levels at different possible funding levels. The vertical axis measures percentages from -20 percent to 30 percent in increments of 5 percent. The horizontal axis measures average annual investment in billions of 2000 dollars from 60 to 110 in increments of $10 billion. The graph shows projected changes in average pavement roughness, average speed, and total highway user costs between 2000 and 2020 at various levels of investment. At lower levels of investment, user costs and pavement roughness would be higher in 2020 than in 2000, while average speeds would be lower. At higher levels of investment, average pavement roughness and total user costs would be lower in 2020 than in 2000, while average speeds would be higher.
