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.
Star college gymnast, 21, shot dead in off campus home, 23-year-old boyfriend arrested
Loved ones are completely shattered by the “heartbreaking” death of Kara Welsh, a 21-year-old star gymnast, who was shot to death by a man identified by college friends as her boyfriend.
The national champion was found dead in her off-campus apartment on August 30, and a friend of the couple says he “beats” himself up for not sharing “just one more” moment that maybe “could change” what happened.
Keep reading to learn about Welsh’s tragic death.
On Saturday August 31, Sierra Brooks learned Kara Welsh, her best friend and former teammate, was shot to death the night before.
“I can’t even wrap my head around how someone could do this, let alone to such a beautiful person,” she writes in a tribute to the 21-year-old Welsh, a University of Wisconsin-Whitewater (UWW) student who was majoring in business and economics.
Welsh, a gymnast, also won an individual title on the vault in 2023.
According to a statement, the student, from Plainfield, Illinois, was found dead in an off-campus apartment about 11:54 p.m. on August 30.
She was shot multiple times.
When police arrived, a 23-year-old male who was known to Welsh was also in the home and “it was determined that leading up to the shooting, an altercation had occurred between the two.”
‘Heartbreaking’
“Absolutely heartbreaking to receive a phone call like this one. Kara, you deserved the world and more,” shares Brooks, who in her earlier years trained with Welsh at the Aspire Gymnastics Academy. “Wish I could just see you one more time. Wish I could laugh with you just one more time. Wish I could hug you one more time.”
Aspire also shared several photos of the star gymnast along with a touching tribute for the young woman on their Facebook site.
“As Kara grew, so did Aspire. She was a constant in a sport that is filled with ups and downs. She was full of life and full of personality,” the training center writes. “Kara had a way of communicating through facial expressions that was second to none. Aspire lost a piece of its heart today. Kara, we love you.”
Corey King, chancellor at UWW, released a statement on August 31 and calling Welsh “a standout member of the Warhawk gymnastics team,” he shares that “news of Kara’s death is heartbreaking for our close-knit university community.”
“I hate that evil touched this sweet girl’s life,” writes a friend on Facebook, who shares the tribute posted by Aspire. Referring to Welsh’s sister Kaeli, the netizen continues, “The Welsh girls showed us how to be gym sisters but so much more. Kara was all heart. The loss is unfathomable.”
‘I beat myself up’
Police have not yet released the name of the suspect as he has not yet been officially charged.
But friends reveal the pair were dating, and the man, identified as Chad Richards, was helping Welsh move into her apartment.
“Sometimes I beat myself up, if I was able to see them that day maybe…just one more joke one more memory we could make…could change…” says Brayten Wilkerson, a friend of both Welsh and the suspect, who was a member of UWW wrestling team. Speaking with ABC affiliate WISN, Wilkerson continues, “Kara was a sweetheart. She was one of the best people you could meet. Her family did a great job raising her – a wonderful woman.”
