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.
The Mysterious Reason Why Zac Efron Moved to a Different Country and Changed His Lifestyle
Zac Efron has been a globetrotter since gaining fame, often jetting off for both business and pleasure. Despite this, he maintained his California roots, his birthplace, and his hometown. However, everything took an unexpected turn when he opted to spend more time overseas, leading him to rethink his lifestyle in search of genuine happiness.
He lived most of his life in the United States.
Originally from San Luis Obispo, in California, Zac Efron spent the majority of his life in the United States, having grown up close to the heart of Hollywood. Despite this, his parents were never involved in the entertainment business. Still, he took his first steps into that world early on in his life. His journey in acting and singing began during his time at Arroyo Grande High School in the early 2000s, with a drama teacher playing a pivotal role in connecting him to an agent.
After he achieved success with teen flicks like the High School Musical trilogy and 17 Again(2009), he shifted into more dramatic roles in films such as The Greatest Showman(2017) and, more recently, Extremely Wicked, Shockingly Evil and Vile(2019). It was this ever-growing filmography that allowed him to amass a net worth of around $25 million and allowed him to purchase a mansion in Los Feliz, Los Angeles, in 2013. He lived there for seven years until he no longer felt like it was the right place for him.
So, what happened to Zac Efron to make him change his mind? Keep reading to find out.
His L.A. house had everything to offer, but ultimately it wasn’t enough.
The 36-year-old actor put his Los Feliz home up for sale in December 2020, and the listing made public the house’s astounding features. The property, which is nestled against the Hollywood Hills and located in a prestigious neighborhood filled with plenty of celebrity residents, offers breathtaking views, accentuated by walls of glass, terraces, and numerous outdoor spaces that offer panoramic vistas of the city below.
With five bedrooms and five bathrooms within its 5.455-square-foot layout, the main level includes a living area, dining room, chef’s kitchen adjoining a family room, and a master suite with a spa-like bathroom. But that’s not all!
Additionally, it has three bedrooms with bathrooms downstairs, along with a separate one-bedroom, one-bath guesthouse. It also features amenities such as a gym, media room, game room, and security cameras, and the outdoor space includes view decks suitable for outdoor dining and lounging.
So, with all its potential, it wasn’t shocking that it sold in only a few months, despite the hefty price tag. In May 2021, the house sold for $5.3 million. Albeit below the initial asking price of $5.9 million, it still marks a profitable venture for Efron, as he paid around $4 million when he first purchased the property.
He fell in love with a different country.
In 2020, Efron made a move that had a deep impact on him — he relocated to Byron Bay, Australia. Back then, he still owned the Los Feliz mansion, so many thought it was just a temporary home. The fact that he lived out of a van, before buying a property in the Australian beachside town also led many to believe nothing much could come of the move.
However, he shot the second season of his Netflix documentary series Down to Earththere, which allowed him to spend over a year with the Aussies. Eventually, he did return to the US to enjoy quality time with his family, but it wasn’t long before he was once again on Australian ground. This time, it was to shoot Ricky Stanicky, a movie in which he co-stars with John Cena and that has yet to have a set date for its debut.
But a special situation might have sealed the deal for his ever-growing bond with the country. Shortly after he moved to Australia, Efron found love. He met Vanessa Valladares, a waitress at the Byron Bay General Store & Cafe, in June 2020. They began dating and eventually spent Christmas and New Year’s together in Australia. Although the couple has since called it quits, the relationship might have been the final trigger of Efron’s decision to move permanently from the US, as he then put his L.A. home on the market.
Finally, a source close to the actor revealed in January 2021, that Efron already considered Australia «home.»
The actor doesn’t think Hollywood is a healthy place to live in.
The actor had previously expressed his intention to move out of Hollywood, though, and it was precisely in a scene from Down to Earth. In the fourth episode, he candidly shared his desire to move away from the Hollywood scene and the lifestyle associated with it, and emphasized that it didn’t contribute in any way to a «long, happy, mentally-sound life.»
Curiously, what happened to Zac Efron also happened to Chris Hemsworth, in which both actors decided to move to Australia so they could distance themselves from the hecticness of Hollywood. Although Hemsworth himself is Australian, his mindset was similar to that of Efron.
In 2016, Hemsworth, known for his role as Thor in several Marvel movies, relocated his family from Los Angeles to Byron Bay. The 40-year-old similarly expressed a wish to escape the suffocating nature of being constantly surrounded by the entertainment industry. Opting for a more tranquil lifestyle, as of 2023, he and his family reside in a $20 million mega-mansion in Byron Bay’s hinterland, which they view as a healthier environment for their children to grow up in.
Zac Efron isn’t the only celebrity who decided to move to a new home. Many others did as well, and they spared no expenses to buy the luxury house of their dreams. We listed a few of the most expensive celebrity homes here and showed what makes them extraordinary.
