- [Narrator] Information from the Automated Traffic Signal
Performance Metric system is used to improve efficiency
and safety for drivers.
The Texas Department of Transportation
along with researchers from the University of Texas
at Arlington work to develop the ATSPM in the loop
simulation framework filling the gap between planning,
design and implementation stages.
- We realized that it's important to incorporate the ATSPM
concept into traffic signal planning and design
before we actually deploy it.
Plus, we need a better training program to help Texas
operate the system and gather most out of it
and to tackle these challenges,
we're using traffic simulation as a stand in for ATSPM data.
This way we can test the traffic signal timings
before deployment and show how ATSPM system works.
- We create a new solution or software package
to connect simulation and traffic simulation
and ATSPM system 'cause two system
they belong to different worlds,
they don't know each other in the last 20 years.
So using the simulation of the output to feed
the real world ATSPM system, as a result the ATSPM system
can generate all the performance measures
the same as they are being generated in the real world.
- We got the green light for phase two project
to fine tune the software and documentation
and we plan to use these two
in our current deployment projects.
- This tool is really help them to quickly pick up
the experience or provide a scientific tool
even for the new traffic signal engineers
when they design a system with this complexity.
So instead of using the experience from a supervisor
or mentor or have to develop by themself
they can simulate users to see what's going on there.
- This project can really improve
how we design traffic signals,
especially the more complicated ones.
It also boosts the training program for ATSPM (indistinct).
This systems basically makes traffic signals
that are more efficiently and safely
which is great news for everyone on the road.
