Example 2 — Residual Value

In the following example, which uses a percentage driver, the allocation of values to subsequent assignments leaves a residual value at the original intersection.


This graphic displays an assignment that has a residual flow, as explained in text after the graphic.

Stage A contains $100. Based on the percentage drivers, allocations to intersections in Stage B account for 80% of the value of the original amount. These assignments mean that 20%, or $20, of the original amount remains unallocated. The $20 is treated as IdleCost.
