What are the black tubes that run across Texas roads?
TEXAS (KXAN) — Those traveling across Texas have probably seen — and driven over — a slew of black cords running across roadways. But what exactly are they, and how are they used?
The U.S. Department of Transportation’s Federal Highway Administration (FHWA) calls them “pneumatic road tubes,” an in-roadway sensor that can help detect and track vehicles traveling on roads. They’re typically used as short-term traffic counts, with some models having the ability to gather data related to the following:
- Gaps between vehicles
- Intersection stop delays
- Stop Sign delays
- Saturation flow rate
- Spot speed
- Traveling time
Alongside their uses in short-term traffic counts, they can be used to detect vehicle classification (via axle count and spacing) as well as assist with planning and research studies. But how, exactly, do they work?
How does it work?
The tubes are portable and are placed perpendicular to the direction of the traffic flow. When a vehicle’s tires drive over the tube, the tube’s sensors “send a burst of air pressure along a rubber tube,” per the FHWA.
That air pressure pulses close to an air switch, which is able to create an electrical signal that’s then sent back to a counter or analysis software synced with the tube.
Here in the Lone Star State, the Texas Department of Transportation collects roughly 82,000 short-term traffic volume counts each year along with approximately 1,000 vehicle classification counts, per its traffic count maps database. Among those counts collected, nearly half of them — 46.9% — are used to track traffic volume, according to the database.
The state department has more than 300 permanent count locations across Texas that collect data around the clock. KXAN reached out to TxDOT to confirm how many pneumatic road tubes are used as part of those traffic data collections. We will update this story once we’ve received a response.
There was a significant reduction in the number of antisemitic incidents in Rhode Island in 2025, according to a national Jewish advocacy group.
According to the Anti-Defamation League’s latest Audit of Antisemitic Incidents, there were 26 antisemitic incidents in the state last year. That’s down from the 52 incidents counted by the group in 2024.
Samantha Joseph, New England regional director of the Anti-Defamation League, says a big reason for the reduction is a steep decline in antisemitism on college campuses.
“It shows that campus administrators are taking their responsibilities very seriously to provide a safe environment for all of their students,” said Joseph.
Brown University had over $500 million in federal funding frozen by the Trump administration last year following investigations into alleged antisemitism on campus. The funding was restored after Brown reached a settlement with the administration.
The reduction in antisemitic incidents in Rhode Island reflects a wider trend in New England as a whole. According to the ADL’s report, there were 400 antisemitic incidents in the region in 2025, compared to 638 the previous year.
While she’s pleased about the overall drop in antisemitic incidents in Rhode Island, Joseph says a number of concerning trends continue to persist. In particular, the state is still seeing more anti-Jewish incidents than it did prior to the October 7 attacks on Israel that launched the Gaza War in 2023.
Joseph is also concerned about the violent nature of local incidents of antisemitism.
“Even though overall incidents are down, assaults are up and assaults with a deadly weapon are up significantly,” said Joseph. “Our communities remain concerned for their safety, and our work is far from done.”

Money and rankings don’t make a great university. Providing opportunities for disadvantaged students and protecting academic freedom, however, do.
Case in point: Michael and Susan Dell recently surpassed $1 billion in giving to the University of Texas at Austin, launching a plan to build a new medical center and advanced research campus in north Austin.
To be sure, this is a magnanimous gift that will fund important initiatives. While enormously grateful for this contribution, I am disappointed that this gift was not accompanied with a strong message from Michael Dell admonishing the University for gutting DEI and infringing upon academic freedom.
As a colleague of mine astutely observed: “Good luck recruiting doctors and med students. The attacks on DEI and political climates will mean a lot more than rankings and money long-term.”
UT System Board of Regents Chairman Kevin Eltife, referencing the Dell gift, is right: “We are transforming this site into a new campus the world has never seen before.” Yes, never seen, but in a very negative and dangerous way!
Last week, I received a message from the Texas Exes: “This is your last chance to show your support during 40 Hours for the Forty Acres, UT Austin’s Texas-sized fundraising event. Can we count on you?”
My answer: “No, absolutely not. I won’t give one dime to a university that no longer is committed to diversity and preserving academic freedom.”
Having proudly taught at UT for 41 years, I am sad to say this.
