The V2I
Communications for Safety research program is comprised of three tracks that
define the work program.
|
|
Track 1, Enabling
Technologies – will culminate in the V2I Reference Implementation, which
will include the standards, specifications and interfaces for hardware and
firmware that can be used in the connected vehicle environment. The V2I
Reference Implementation will also include a physical manifestation, a
complete system of the hardware and firmware that can be used to evaluate
potential applications and be used to insure new systems are compatible and
interoperable with other components.
|
|
Track 2,
Application Selection, Development and Evaluation – builds on crash
analysis work to select V2I Safety applications that have potential to
significantly reduce the cost of traffic crashes. Work has progressed through defining
Systems Requirements for three priority safety applications (red light
violation warning, stop sign gap assistance, and curve speed warning). On-going work includes development of
Systems Requirements for an additional set of potential applications, including
rail-grade crossing warnings, vehicle restrictions (height/weight), speed
management (e.g.: school zones and work zones), Stop Sign Violation, and work
zone warnings (including alignment changes and active/inactive
notifications).
|
|
Track 3,
Infrastructure Planning and Policy – includes various efforts to
establish governance and business models for V2I Communications. The AASHTO “footprint” study is part of
this track. Systems analyses are being
conducted to determine what components and capabilities are the absolute
minimum required if an agency desires to support safety, mobility, data
capture, and environmental applications.
Work under this track will incorporate the standards and
specifications produced under Track 1, and the CBAs for various applications
developed under Track 2, to assist agencies in making deployment and
investment decisions. The final
product of this track are Public Agency Guidelines and Specifications, which
are intended to help decision makers identify the total costs of
participating in the connected vehicle environment, including potential
liability and regulatory issues, and also define the anticipated benefits,
including improved safety, reduced congestion, performance/asset management
issues, and environmental impacts.
