IF YOU EVER SEE BLACK CABLES STRETCHING ACROSS THE ROAD, THIS IS WHAT YOU SHOULD DO

Unveiling the black road cables: Silent traffic observers capturing data for smarter road networks. Data-Driven Traffic Insights

As you navigate the highways and byways of your daily commute, you may have encountered an intriguing sight: black cables stretched across the road, almost like stealthy sentinels of the pavement. But what exactly are these enigmatic tubes, and what role do they play in our transportation infrastructure? The answer lies in the realm of traffic management and data collection.

These unassuming black cables are, in fact, portable traffic counters strategically placed by transportation authorities for research purposes. Primarily used by local agencies, these tubes hold vital insights into road usage and traffic patterns. With more than 12,000 of these traffic counters scattered across the state, they provide invaluable data that fuels the planning and development of our road networks.

Decoding the Mechanism Behind the Black Cables

The technology driving these unobtrusive rubber cords is elegantly simple yet remarkably effective.2 Each time a vehicle’s tires contact the tube, a burst of air is triggered, setting off an electrical signal recorded by a counter device. This ingenious pneumatic mechanism can track the volume of vehicles passing over a road within a given timeframe. Transportation agencies can gain insights into peak traffic congestion periods by analyzing the intervals between these air bursts. When deployed in pairs, these tubes provide even richer data, enabling the determination of vehicle class, speed, and direction.

Such information is far from trivial—it forms the bedrock for informed decisions on road signage, speed limits, and allocation of transportation budgets. Based on these insights, municipalities can fine-tune their traffic management strategies, ensuring that road systems remain efficient and safe for all road users.

Road Tubes: Beyond Just Counting

While the primary function of these pneumatic road tubes is traffic counting, their utility extends far beyond mere enumeration.3 These inconspicuous instruments serve as multi-dimensional data collectors, playing a pivotal role in enhancing our road infrastructure and ensuring smooth traffic flow.

The U.S. Department of Transportation sheds light on the operational intricacies of these tubes. When a vehicle’s tires traverse the rubber tube, a burst of air pressure is generated, closing an air switch that sends an electrical signal to a counter device. These tubes can be set up either as temporary or permanent installations, each serving distinct purposes. Temporary configurations, often lasting only a day, offer quick glimpses into traffic dynamics, while permanent setups provide continuous, in-depth monitoring.

Transportation agencies strategically position these black cables in areas with minimal interference, targeting straight stretches of road for optimal data collection. Through single-tube setups, agencies can gauge vehicle counts and time gaps between vehicles. When utilizing paired tubes, the system delves into the intricacies of traffic, capturing axle count, direction, and speed.

These unassuming tubes also step in when urban road management faces challenges. If residents raise concerns about speeding or shortcutting, these tubes are deployed to investigate and validate claims. The data they generate contributes to the formulation of transportation budgets and the implementation of effective solutions.

In conclusion, the next time you encounter those mysterious black cables stretching across the road, you can appreciate the intricate web of data they weave behind the scenes. These unassuming instruments serve as silent observers, capturing the heartbeat of our roads and guiding the decisions that shape our transportation landscape. As you pass over these tubes, remember that they are more than meets the eye— they are the pulse of our evolving road networks.

Tragic events bring orphan colt, mare together

An orphan colt whose mother died shortly after giving birth has a new mom – a mare that had tragically lost her foal – thanks to the generosity of strangers and Washington State University veterinarians playing matchmaker.

Pairing an orphan foal and a nursing mare is a challenging task and one that commonly ends with failure. In this case, the connection was instantaneous. 

“The mare had only been without a foal for about 24 hours,” Dr. Lisbeth Matthews, an equine medicine and surgery intern, said. “We walked her into the Veterinary Teaching Hospital and past him. He made a noise, and she went, ‘oh, there’s my foal,’ and started making noises back at him.”

It was a surprise to everyone how quickly the mare, named Shelly but affectionally called Mama by her owners, Roy and Faye Lions, accepted the colt. Equine veterinarian Jenifer Gold, who was helping to care for the foal and to supervise its introduction to the mare, said nursing mares frequently reject orphan foals, and when they don’t, the pairing process often takes days. 

“She walked in and started nickering at him like it was her own baby – it was unbelievable,” Gold said. “I’ve been doing this for 20 years, and I have never seen it happen that way.” 

The foal, which has been named Laredo, was admitted to the teaching hospital by his owner, Spokane resident Rachel Williams, just days after he was born when he started showing troubling digestive issues. Shortly after the colt arrived in Pullman, Faye Lions placed a call to WSU to see if the equine team was aware of any orphan colts needing a nursing mare.

“Our foal was dead, and nothing was going to bring it back, so we were hoping we could help someone else,” Faye Lions said. “It just so happened there was a foal there.”

A day later, the colt and Shelly were introduced. 

“For them to be so willing to basically hand over their animal to a complete stranger after experiencing their own tragedy was pretty phenomenal,” Williams said. “I feel like in this scenario it was the worst of the worst for everybody, but there was a little bit of silver lining to the story.”

Williams is also grateful for the care and treatment she and her foal received at WSU. 

“I just can’t even find words to say how great the veterinarians at WSU were,” she said. “They went above and beyond. I am just happy I ended up at WSU. I am so glad we were able to match those two up – it is kind of a miracle.”

Shelly will live with Williams until the colt is ready to be weaned, likely in six months, before she will return to her home in Kamiah, Idaho. 

“It will be tough to say goodbye because you just naturally start to bond with animals, and she has kind of been my lifesaver,” Williams said. “It will be bittersweet for sure, but I am sure her owners will be happy to have her back.”

During the spring, the equine team at WSU typically sees at least a handful of orphan foals. Equine medicine specialist Dr. Macarena Sanz said orphan foals can be fed a powdered milk formula designed for horses, but those raised by humans typically develop behavioral issues that can become problematic as the animal matures. 

“They turn out to be socially weird, have no understanding of personal space, and they are more difficult to train,” WSU equine veterinarian Macarena Sanz said. “The fact that this orphan foal has a mare is really going to make a difference.”

Sanz strongly encourages owners to immediately call their veterinarian if a foal is orphaned, as early care is critical to the animal’s survival.
