The objective of the
BCA is to assess the benefits and costs of the applications for the entire
United States.
|
|
The first step is to
develop a “baseline” scenario (which includes connected vehicle
infrastructure installed for safety and mobility applications), this is the
world without AERIS applications and includes projections of fuel prices,
vehicle miles travelled, etc.
|
|
The second step is
to estimate benefits for the applications on a unit basis (i.e. per vehicle).
These values are then monetized ($) for each environmental benefit category
(GHG and criteria pollutant emissions and fuel savings). The unit benefits
and monetary values change over time, this is accounted for in the model.
|
|
The third step is to
estimate the costs on a unit basis (i.e. per road mile) associated with the
applications. Cost elements may have capital and/or operating costs as well
as a life associated with the element. These are accounted for in the model.
|
|
The deployment
assumptions for baseline RSEs, OBEs, and applications are utilized to
determine the number of applications deployed and requirements for cost
elements and benefit potential. The model calculates benefits and costs for
the nation for each year in the analysis and net present value (the
discounted (7%) value of the cumulative project).
|
|
There is a great
deal of uncertainty and we conducted some initial sensitivity analyses
including testing assumptions related to deployment as well as compliance
rate.

A similar model is
being used for analyses in the Road Weather Program and CDDS
