Risks
|
|
The greatest risks
are not technical but institutional.
|
|
An appropriate
financial model must be in place since the benefits distribute widely but the
costs are borne narrowly. The
operating expenses of the Core could be part of the DOT budget. It could be subsidized or paid for by user
fees and sale of the collected data.
The policy must be in place beforehand to ensure successful operation.
|
|
The most significant
benefits not realized until sufficient penetration of connected vehicles in
the traffic stream. That means if
penetration takes longer to build up than anticipated, the cost savings and
other benefits will likewise take longer to materialize delaying the return
on investment.
|
|
In addition, a gap
in the connected vehicle environment due to either a gap in communications
coverage or regions not serviced by a Core System (late deployers) will
substantially reduce the benefit for those that have the Core System in
place.
|
|
The skills to
operate a Core System may be in high demand if current educational pipelines
are not synchronized with anticipated demand.

Other
Considerations
|
|
|
|
Owner/Operator
versus Participator
|
|
A local DOT may be
able to use an existing Core especially if already put in place by the State
DOT. If not the local DOT may need to
establish its own minimum Core System to gain these benefits. A large municipal region may want to
operate its own Core anyway for greater control and reliability.
|
|
A State DOT may want
to operate a Core System because no other entity is likely to operate a Core
with statewide coverage. Operating the
Core may be the best way to address rural and urban needs in an integrated
fashion that satisfies all stakeholders.

Outstanding
Questions
|
|
What barrier will
the minimum requirements to operate a Core System pose to States and smaller
local DOTs?
|
|
What happens to
traffic control and traffic flow at boundaries across operating regions where
one has a Core System and the adjacent region does not?
|
|
Could there be a
Core System with multiple-State coordination?
For example, a jointly-operated or franchised Core System to serve a
multi-State corridor or a metro area that overlaps multiple States?
