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.
Helen Mirren believed that the bikini snapshot her husband captured of her on the beach would remain a private, intimate moment – but internet didn’t listen
Helen Mirren has definitely earned a legion of fans throughout her more than 50-year career as an actress, and her commitment to ageing naturally has garnered her even more popularity.
Mirren started off in the entertainment industry as a theater actress, joining the Royal Shakespeare Company before making her debut on London’s West End in 1975.
Though, the now-78-year-old didn’t become a household name until later on in her life – she was 35 when she landed her breakout role as a gangster’s girlfriend in ‘The Long Good Friday’ (1980), opposite Bob Hoskins.
Having focused on her career for much of her adult life, finding the right partner and having children wasn’t on Mirren’s radar… Until she met her now-husband – US film director Taylor Hackford.
“I was 38 when I met Taylor, pretty late in life,” she stated in a 2016 AARP interview, recalling how the director had kept her waiting for an audition when they first met. When she eventually landed the part, the pair got to know each other and their relationship grew from there.
Eventually, Mirren and Hackford were able to bond over their similar working class upbringings (her mother was a working class woman whose own family came from a long line of butchers, while Mirren’s father was a Russian aristocrat who escaped to the UK during the Russian Revolution and became a cab driver to support his family).
The future spouses also bonded over their love for traveling, and apparently had a similar view on storytelling, both being in the entertainment industry.
Even though Hackford’s two children from previous marriages supported Mirren’s union with their father, this didn’t change her stance on becoming a mother herself. Though, she did explain that she found Hackford’s dedication to being the best parent to his children rather endearing.
The pair eventually married in 1997, after they came to the realization that they knew they would be together forever. At that point, they’d been together for over a decade.
The infamous swimsuit photo
Fast forward to 2008, and Mirren went viral for an image her husband snapped of her at the beach… Something that stunned fans and even the legendary actress herself!
The married couple had been on a romantic Italian beach vacation when they trekked to a secluded beach spot to take in the breathtaking views in private.
She recalled how she took a photo of her husband and then, in return, he snapped a quick pic of her. Though, Mirren said that the moment she sucked in her stomach when posing, she saw a small flash in the distance and crouched down on the rocks to hide from the apparent paparazzo.
When Mirren’s husband turned around, he couldn’t see the paparazzo, and said his wife was just being “paranoid”. Though, sure enough, the photo taken of Mirren in a red bikini was posted by a tabloid and went viral everywhere.
A few years later the actress told Ellen DeGeneres on the latter’s talk show that the image was just a fluke, saying: “I look at that picture and say, god, I wish I look like that. But I don’t.”
Years later, people are still stunned by the image of Mirren, who was 63 years old at the time it was taken – with many people on the internet commenting that they don’t look half as good as her despite being decades younger!
In 2014, the Oscar winner spoke about the image just before her 68th birthday, telling People: “The truth is I don’t really look that good, it was just a flattering picture.”
She added: “I am beyond the bikini-wearing age, really. I wouldn’t normally wear one. I look like a woman in her 60s. I’ve always looked awful in a bikini, even when I was young.”
