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.

Highly pathogenic virus found in herd of Texas dairy cows
AUSTIN, Texas – State and federal agriculture officials said highly pathogenic avian flu has been found in a herd of dairy cows in Texas.
What we know:
Officials said the H5N1 virus was confirmed with laboratory tests in late May after cows at an unspecified farm became sick and milk production dropped. The dairy has since been quarantined and an investigation is underway.
This is the first case of avian flu in a Texas dairy herd this year, officials said.
What they’re saying:
“The U.S. Food and Drug Administration (FDA) is confident that pasteurization is effective at inactivating H5N1, and that the commercial, pasteurized milk supply is safe,” officials at the Texas Animal Health Commission said in a statement.

Dig deeper:
H5N1 has a high rate of severe disease and death in animals that become infected.
According to the Centers for Disease Control and Prevention, the risk to the general public from avian flu is low. Some sporadic human infections have been reported around the world since 1997. There have been no known cases of person-to-person spreading of avian flu.

New Texas law tightens rules for autonomous vehicle companies, including Waymo
AUSTIN, Texas — Self-driving cars have become a common sight on Austin streets, but a new Texas law is adding tougher requirements for the companies behind the wheelless vehicles.
Senate Bill 2807 imposes stricter rules on autonomous vehicle companies operating in the state, including state authorization, emergency response plans for law enforcement, and a public portal where residents can verify operators and file safety complaints.
The changes come as Austin continues to track incidents involving autonomous vehicles. The city’s autonomous vehicle dashboard shows 75 incidents in 2026, including a collision, eight near misses, and seven incidents of ignoring police direction.
Attorney Drew Gibbs, a partner at Slingshot Law, said one crash involved a Waymo vehicle.
“There was a T-bone collision. A pretty serious T-bone collision where a Waymo just crashed into the side of my client’s vehicle,” Gibbs said.

One of the incidents of ignoring police direction happened during the mass shooting on West Sixth Street back in March, when three people died, and 15 others were injured.
Austin Police Association President Michael Bullock said autonomous vehicles can struggle in unusual situations.
“It didn’t impede on anything in the moment, but it’s not necessarily uncommon where these vehicles don’t quite know how to deal with these one-off scenarios,” Bullock said.
The new law requires autonomous vehicle companies to be authorized by the state, to provide an emergency response plan for law enforcement, and to participate in a public-facing portal that allows the public to verify operators and submit safety complaints.
Kara Kockelman, a professor of transportation and engineering at the University of Texas at Austin, welcomed the added oversight.
“I’m glad that the state is taking this a bit more seriously now,” she said. “It’s important not to just let others slip in without kind of meeting those basic minimums.”
Bullock said the emergency planning requirement may not make a major difference in fast-moving situations. Asked how impactful it is to have a fully laid out emergency response plan, Bullock said, “These plans are great, but it takes time to work through all of those versus the immediacy of having someone behind the wheel.”
The four autonomous vehicle companies operating in Austin — Waymo, Zoox, AV-Ride, and Tesla — are all state-authorized.
The Texas DMV said an autonomous vehicle company can lose its authorization to operate in Texas if the agency deems the vehicles are operating in a way that endangers public safety.
Waymo was contacted for comment, but had not responded.
