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.

Samsung is taking steps to provide Apple with image sensors built with advanced technology for iPhones. Reportedly, the sensors for the iPhone will be manufactured in Samsung’s current Austin, Texas facility, and the company is anticipated to soon have production equipment installed for the upcoming project.
The image sensor of the iPhone is expected to have a three-stack design for better low-light performance and a higher density of pixels with multiple layers stacked vertically. This results in less power consumption, a dynamic range that’s higher, and faster speeds for readouts.
It’s believed that the new sensor will be made for the upcoming iPhone 18 in 2027. Apple and Samsung have reportedly arrived at a deal where Samsung will be supplying the component for the sensor. This marks the first occasion Apple will be going with another company apart from Sony as their main supplier for image sensors for its iPhones.
Texas football has lost its fair share of players to the NFL draft and transfer portal over the past few weeks, dwindling the roster. Despite the loss of a few big names such as linebacker Anthony Hill Jr., safety Michael Taaffe and others, the Longhorns have held onto star quarterback Arch Manning.
While it was unlikely that Manning would enter the portal, there was some hype surrounding the possibility of the first-year starter entering the NFL Draft. Why did the young star decide to forego the pros? According to Manning, his journey at Texas isn’t quite finished.
Manning Wants to Continue His Development With Texas

“I felt like I developed a lot this year, especially towards the back half, and I want to keep it going,” Manning said, according to Inside Texas’s Evan Vieth. “There’s no reason to leave. I feel like I got a lot more football left to play, and excited to still be a part of this team.”

Manning didn’t quite have the season that most fans and analysts envisioned for him, struggling at the start of the year. Despite these struggles, Manning went on to improve throughout the regular season, demonstrating why he is one of the nation’s top quarterback talents.

At the start of the season, Manning’s accuracy and timing were a bit off. The offense as a whole seemed out of sync, and Texas was not looking like the powerhouse that was promised heading into the season.
Eventually, though, Manning found his stride, and more than just improving his stats, the Longhorn quarterback looked more comfortable. Eventually, the stat sheet reflected his improvements, posting 1,625 passing yards over the last six games of the season, alongside 16 total touchdowns.
Now, returning to Texas for what will likely be his last year in college before departing for the NFL, next season should be an exciting one for the Longhorns. Not only is Manning more experienced as the team’s top quarterback, but the wide receiving core will have developed as well.
Texas wide receivers had their struggles with drops this season, but showed improvements at some points throughout the year.

Though it may be difficult to abstain from declaring for the draft, ultimately Manning made perhaps the best decision for his career and development. With another year to grow, by the time he enters the NFL, Manning will be much more experienced and likely better prepared.

Manning will have one more chance to take the field this season in the upcoming Citrus Bowl, where Texas will take on the Michigan Wolverines on December 31.
