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.
Donald Sutherland dead at 88: iconic actor starred in “MASH,” “Ordinary People,” “Hunger Games”
Sutherland was born July 17, 1935 in New Brunswick, Canada, later moving to Bridgewater, Nova Scotia. Throughout his childhood he battled a number of serious illnesses including polio, rheumatic fever and spinal meningitis.
He left Canada to pursue an interest in acting at the London Academy of Music and Dramatic Art, and soon found work in TV and low-budget films.
He got a Hollywood breakthrough in the classic war film The Dirty Dozen, whose ensemble cast includes Lee Marvin, Charles Bronson, Ernest Borgnine and Jim Brown. It was the fifth highest grossing film of 1967.
After leaving London for Hollywood, Sutherland landed one of his most iconic roles in the 1970 anti-war comedy-drama MASH, originating the role of “Hawkeye” Pierce. MASH was one of the most successful films of the decade and is regarded as a classic.
Throughout the ’70s, Sutherland was a Hollywood leading man: his films include in the Oscar-winning Klute opposite Jane Fonda, the psychological horror Don’t Look Now, and the remake of Invasion of the Body Snatchers. He also appeared in the hit comedy Animal House.
In 1980, he starred in Robert Redford’s Ordinary People, which won the Academy Award for Best Picture. Other major films include Backdraft, JFK, Six Degrees of Separation, The Italian Job and Pride and Prejudice.
Sutherland also had success on TV, winning an Emmy Award for the 1995 film Citizen X, and a Golden Globe for the television film Path to War.
A younger generation of moviegoers was introduced to Sutherland through The Hunger Games, the hit dystopian blockbuster series: Sutherland starred as the villainous President Coriolanus Snow.
Though he surprisingly never received an Oscar nomination, he received an Academy Honorary Award in 2017, “for a lifetime of indelible characters, rendered with unwavering truthfulness.” He also received a star on the Hollywood Walk of Fame in 2011, and on the Canadian Walk of Fame in 2000.
Sutherland was married three times; he was married to actress Francine Racette for 52 years until his death. He was previously married to Lois May Hardwick and Shirley Douglas, and also had an affair with his Klute co-star Jane Fonda.
He had five children — including most famously his son Kiefer Sutherland, the actor best known for playing Jack Bauer in 24.
”I was too young to go watch my father’s films in the cinema,” Kiefer Sutherland told The Hollywood Reporter in 2017. “By the time I hit 20, VHS was available and a friend of my fathers had a lot of his films. In three days I watched Don’t Look Know, Klute, M*A*S*H, Kelly’s Heroes, 1900 and Fellini’s Casanova.”
“It was such a wide spectrum of characters, and I remember calling him up and I felt really badly that I grew up not knowing what a profoundly special actor he was, I felt horribly guilty of that. As a young actor, I had never known or seen another actor who’ve done characters so diverse either.”
Rest in peace to the iconic actor Donald Sutherland who lent his talents to so many great, classic movies — you will be missed 💔😢
