- [Narrator] As the use of connected vehicle technology
increases in Texas,
so does the need to standardize data sharing
between various transportation stakeholders.
The Connected Vehicle Data Framework, or CVDF,
allows TxDOT to share data,
like work zones and travel times,
and enables data exchange with third-party applications.
The Texas Department of Transportation,
with researchers at the Center for Transportation Research
and Southwest Research Institute,
work to expand the capabilities of the CVDF
to improve data sharing capabilities
and provide new benefits to Texas road users.
- The Connected Vehicle Data Framework, we call it the CVDF,
is a standardized way for TxDOT to share information,
usually that they already have,
about roadway conditions or weather
or any traveler information with the public
and third parties, like mapping providers, Google Maps,
Waze, that sort of mapping solution.
It really allows for realtime information that can help
with both safety and mobility across TxDOT roadways.
- The Connected Vehicle Data Framework
provides a standardized way for TxDOT to share information
with travelers and third-party data providers
like mapping companies, so this realtime information
can enhance the safety and mobility of everyone on the road.
- For each of the priority applications that we identified,
I mentioned that we establish reporting, formatting,
and data use standards.
Those really don't exist to date, so it's a foundation
for TxDOT to start to build a standardized,
streamlined data sharing portal
between TxDOT and the public sector, and then lastly,
we evaluated opportunities for partnerships
with third-party data services,
either to augment applications that are already supported
by the CVDF or to expand data availability
and quality for new applications.
- The most important feature that we added
was developing that road weather warning application
within the Connected Vehicle Data Framework,
and that can be used to communicate critical information
about flash flooding, any low water crossings,
potentially icy bridge conditions, or any powerful winds.
We simulated various weather conditions
in the test environment at Southwest Research and verified
that the road weather warning application performs.
- The road weather warning application
was developed and tested in a controlled environment,
so the next step is to roll it out to all TxDOT districts
through a Lonestar update.
- So we developed the one application,
but we also identified, I think,
five or six other priority applications,
data partners, strategic corridors,
and this really sets TxDOT up to continue
to grow their connected vehicle technology network
and investments.
