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.
Adriana Lima Stuns with Her ‘Healthier’ Body on the Runway
The Brazilian supermodel made a comeback on the runway at the age of 43, showing off her “slim” body transformation for the 2024 Victoria’s Secret Fashion Show.
Adriana Lima’s appearance at the Victoria’s Secret Fashion Show on October 15, 2024, was one of the best moments of the night. After retiring in 2018, after nearly 20 years with the lingerie brand, and having her third child in 2022, she amazed the crowd with her new look, which fans quickly noticed and praised.
Lima first shared her retirement in 2018 at the age of 37. In an Instagram post, which she has since deleted, she reflected on her long time with the brand. “Dear Victoria, thank you for showing me the world, sharing your secrets, and most importantly not just giving me wings but teaching me to fly,” she wrote.
When talking about her last walk, Lima told People, “This has been my 18th fashion show, and I am still as excited as I was from the first day. I think this year is going to be the highlight of my career.”
After leaving modeling, she was only seen at some events and on social media. In a TikTok video from February 2022, Lima shared that she was pregnant with her third child, her first with partner Andre Lemmers.
By April, the couple released a gender reveal video, announcing that a boy would join Lima’s daughters from her previous marriage, Valentina and Sienna. Her son, Cyan, was born in August 2022.
During her pregnancy, the retired supermodel looked amazing in stylish maternity outfits at important events, like the 75th Cannes Film Festival in May 2022. Wearing a mustard gown from Nicolas Jebran, she proudly showed off her baby bump on the red carpet, and while she looked great, it was different from her usual slimmer figure.
Fast forward to 2023, Lima attended the Venice International Film Festival in a Pinko gown with a plunging neckline and gold accents. At this event, her fuller face and body were still noticeable.
A few months later, the supermodel went to the Mon Cheri Barbara Tag event in Munich, Germany, in December 2023. She wore a form-fitting gray gown by Donna Karan and looked like she was losing her previous weight.
However, her October 2024 runway appearance showed her full transformation. During the 2024 Victoria’s Secret Fashion Show in Brooklyn, Lima wowed the crowd not just with her outfits but also with her youthful appearance. A backstage photo captured her glowing skin and tight facial features.
Once ready, Lima hit the runway wearing a checker-striped outfit with a black bra and high-waisted pants, topped with a long-sleeved cut-out top for her first look. Her grunge-style angel wings added a cool touch to the outfit.
For her second appearance, she wore a red lace nightie with sparkling wings that showcased her renewed energy. This moment reminded everyone of her younger days as an angel for the brand, and fans quickly expressed their admiration for her physical change on social media.
One fan said, “She’s lost so much weight. She’s back .” Another wrote, “SHE LOOKS GREAT HER SLIM BODY IS BACK. GREAT JOB. I LIKE THIS OUTFIT TOO.”
Kiya Cole, the mother of actress Skai Jackson, added, “She worked hard in the gym this past year! I was a witness. No quick fix for her!” Another commenter expressed, “She is back with a vengeance, love her.”
Fans were also happy to see the show featuring a variety of healthier bodies, like Lima’s. One commented, “These bodies look healthier, and I like that, in different sizes but healthy, good for VS.”
