Discount delay
This is an optional feature that is currently not used.
The idea is to dampen the effects of extreme deficiency while still
being sensitive to changes in V/C above 1. A discount value of .5,
for example, would reduce delay from congestion above V/C = 1
(i.e. below half the FFS) by 50%.
There is really no way to calibrate this number, and to date, using the
conical VDF and scanning the no-build network for extreme V/C and making
needed corrections has been adequate. Setting the discount = 1 effectively
turns off this feature.

Parcel the benefits out into primary and secondary types
Primary: caused by improvement to the link
Secondary: caused by improvements to other, nearby links
For each link, the first step is to calculate the percentage of primary and secondary benefit
Start with rules:
New Links
| Decrease Delay |Increase Delay
Increase Capacity (New Road) | |
Increase Volume | n/a |Primary
Decrease Volume | n/a |n/a
| |
| |
Existing Links | |
| Decrease Delay |Increase Delay
Increase Capacity (Widening) | |
Increase Volume | Primary |Secondary
Decrease Volume | Both (D.D.) |n/a D.D. = decreased delay
Decrease Capacity (Road Diet) | |
Increase Volume | n/a |Both (I.D.) I.D. = increased delay
Decrease Volume | Secondary |Primary
For the cells above labelled "Both", a ratio of primary and secondary benefits
must be determined.
The change in capacity is used to approximate the proportion of primary benefit.
i.e. capacity increases are the result of the project
The change in volume is used to approximate the proportion of secondary benefit.
i.e. volume decreases are the result of improvement in other projects
Thus, the following ratio of ratios:
abs(%change in Cap) / ( abs(%change in Cap) + abs(%change in Vol) )
Absolute value is needed because, while capacity and volume are moving in opposite
direction, you want to know their relative magnitude.
This metric will determine how much of the change in delay on the project is
due to the project and how much is the secondary benefit from other projects.
Example 1: if a link's capacity increases by 20% and it's volume decreases by 10%:
2/3 of the delay reduction is due to the project. That is primary benefit.
1/3 is due to improvements from other projects drawing volume away. Secondary benefit.
Example 2: if a link's capacity decreases by 30% and it's volume increases by 10%:
3/4 of the delay increase is due to the project.
1/4 is due to changes in other links.
