This graph compares your revenues with your expenses over the long term. Current revenues are shown in green, new revenues in blue and any bonding in brown. Your spending is represented by the red line.
As you adjust revenues and programs, you'll see the graphic change accordingly. Instead of the average annual program that much of this Calculator is focused on, this graphic demonstrates how the revenues and programs grow over time.
These numbers represent only the revenues available for construction and distribution to the various modes. Specifically, the "Non-Construction Expenditures" from the "Local Roads, Modes, and Other" tab have been netted out.
NOTE: If you included any additional bonding as a part of your program, you'll notice that your available revenues dip after 2014. This is because the new debt payments have been subtracted out. In the years 2010-2014, the debt payments are netted out of the bond revenues (shown in brown).
