- [Narrator] How traffic signals operate
is traditionally based
on a set of uniform engineering standards
but using real-world data gathered
at local intersections,
agencies can improve mobility and safety
while tailoring operations to specific communities.
The Texas Department of Transportation with help
from the Texas A&M Transportation Institute
has developed a set
of guidelines for identifying data-driven strategies
and techniques to improve traffic signal performance
and operation more responsive to local needs.
- Right now, a lot of our signals are run sort
of in an isolated manner,
which means that we don't get a lot
of information back and a technician would have to go
to the location to be able to troubleshoot.
With advanced traffic signal performance measures,
we get feedback from Signal for not only timing purposes
but also for troubleshooting purposes for basic maintenance,
things of that nature.
- With the advances in technology,
the newer controllers are able to log by 1/10 of a second
everything that's happening at the intersection.
Along with that, the advances
in computation technology allows us tools
to analyze these data so that we have a better idea
of the performance of the intersection continuously
so that we can go back
and see how the intersection is performing
even before we get a complaint about it,
so that we can then proactively respond
to any issues that are at the intersection.

So this project's objective was to evaluate
and assess the various tools that are available
to analyze the high-resolution data that are being logged
by the controllers, and understand the needs of TxDOT
as an agency, understand the needs of individual districts
and develop a systems requirement that would be suitable
for TxDOT for statewide deployment
and develop draft specifications.
- The research objective was trying
to see what equipment is needed, see what sort
of improvements can be made along the corridors.
Larger goals are basically to see
how we can adjust our infrastructure
to meet these additional needs
for the ATSPM and make sure
that we can provide the best travel solution to the public.
- The next step that that would help
in this venture is to have some technology transfer sessions
with the individual districts so that they are more familiar
with the requirements of ATSPM systems.
One of the ways this can also be achieved
is by implementing some pilot deployments of ATSPM Systems.
This will facilitate the transfer of technology
to the individual districts so that they are familiar
with the requirements as well as benefits
of ATSPM systems, and the operation of ATSPM systems.
