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.
“She’s a real Thumbelina” – Meet the girl who’s only 99cm tall and defied all the odds
Kenadie Jourdin-Bromley, a Canadian child from Ontario, seemed ordinary at first glance.
She had high hopes for the future, loved sports and drawing, and went to school.
Nonetheless, one characteristic set Kenadie apart from her peers: her diminutive height of 99 centimeters.
Reports state that when Kenadie was born in February 2023, she weighed a mere 2.5 pounds. Her condition was quickly diagnosed by doctors as an uncommon form of cardiovascular disease, thought to affect only 100 people globally. The nurses dubbed her “Thumbelina,” quite fittingly.
Regretfully, Kenadie had slim chances of surviving.
According to reports, the girl’s condition can lead to complications like delayed mental development, respiratory issues, and digestive issues. Doctors at the hospital where the girl was born were concerned that she wouldn’t have much time to live due to her brain injuries.
Understandably, her parents were devastated. In order to give their little girl a name in case she passed away, they chose to christen her on the day of her birth.
“We thought we were going to take her home to die, because that’s what the doctors told us,” mom Brianne explained to Barcroft TV back in 2016.
Still, as the days went by, Kenadie steadfastly refused to give up. After she triumphed over all the challenges and hardships, her parents were able to dream again that she would survive. It was nothing less than a miracle for them.
Many years later, Kenadie still astounds everyone she encounters. She is only 99 centimeters tall, her arms and legs are still immature, and she struggles to learn new things, but she is a content young girl who enjoys life to the fullest.
Kenadie reportedly enjoys bowling and ice skating. Above all, she makes people happy that she meets.
“Kenadie makes me laugh. She’s very empathetic – if you hurt your finger she comes and gives you a hug. She’s got an infectious laugh that makes you want to laugh along with her,” Kenadie’s assistant Jessica Putnam mentioned to Barcroft TV in 2016.
Naturally, Kenadie and her family face many new challenges in their lives. Despite her loved ones’ best efforts to take each day as it comes, the young girl is continuously dealing with medical issues.
“My hope for Kenadie’s future– my biggest hope for her– is I want her to be happy. I want her to smile and be successful. If we can get through today, then we’ll see about tomorrow,” her mom said.
We are happy to share Kenadie’s inspiring story!
