Why You Sometimes See Black Tubes Stretched Across the Road

If you spend enough time driving down the right route, you may notice them: the skinny black tubes that seem to appear on stretches of road at random. But the scaled-down speed bumps are easy to miss. Unlike other features on the highway, these additions are meant to be used by the government, not drivers.

According to Jalopnik, those mysterious rubber cords are officially known as pneumatic road tubes. The technology they use is simple. Every time a vehicle’s tires hit the tube, it sends a burst of air that triggers a switch, which then produces an electrical signal that’s recorded by a counter device. Some tubes are installed temporarily, usually for about a day, and others are permanent. Rechargeable batteries powered by something like lead acid or gel keep the rig running.

Though the setup is simple, the information it records can tell federal agencies a lot about traffic patterns. One pneumatic tube can track the number of cars driving over a road in any given span of time. By measuring the time that passes between air bursts, officials can determine which time of day has the most traffic congestion. Two pneumatic tubes installed slightly apart from each other paint an even broader picture. Using this method, government agencies can gauge the class, speed, and direction of each vehicle that passes through.

Based on the data, municipalities can check which road signs and speed limits are or aren't working, and decide how much money to allot to their transportation budgets accordingly.

For a closer look at how these tubes are installed, check out the video below.

Attention Business Travelers: These Are the Countries With the Fastest Internet

Whether you travel for business or pleasure, high-speed internet seems like a necessity when you’re trying to connect with colleagues or loved ones back home. Of course, the quality of that connection largely depends on what part of the world you’re in—and if you want the best internet on earth, you’ll have to head to Asia.

Singapore might be smaller than New York City, but it has the fastest internet of any country, Travel + Leisure reports. The city-state received the highest rating from the World Broadband Speed League, an annual ranking conducted by UK analyst Cable. For the report, Cable tracked broadband speeds in 200 countries over several 12-month periods to get an average.

Three Scandinavian countries—Sweden, Denmark, and Norway—followed closely behind Singapore. And while the U.S. has the fastest broadband in North America, it comes in 20th place for internet speed globally, falling behind Asian territories like Japan, Taiwan, and Hong Kong, as well as European countries like Estonia, Latvia, Lithuania, and Spain. On the bright side, though, the U.S. is up one place from last year’s ranking.

In the case of Singapore, the country’s small size works to its advantage. As a financial hub in Asia, it depends heavily on its digital infrastructure, and as a result, “there is economic necessity, coupled with the relative ease of delivering high-speed connections across a small area,” Cable notes in its report. Within Singapore, 82 percent of residents have internet access.

Sweden, Denmark, and Norway, on the other hand, have all focused on FTTP (Fiber to the Premises) connections, and this has boosted internet speeds.

Overall, global broadband speeds are rising, and they improved by 23 percent from 2017 to 2018. However, much of this progress is seen in countries that are already developed, while underdeveloped countries still lag far behind.

“Europe, the United States, and thriving economic centers in the Asia-Pacific region (Singapore, Japan, Taiwan, and Hong Kong) are leading the world when it comes to the provision of fast, reliable broadband, which suggests a relationship between available bandwidth and economic health,” Dan Howdle, Cable’s consumer telecoms analyst, said in a statement. “Those countries leading the world should be congratulated, but we should also be conscious of those that are being left further and further behind."

Samsung Is Making a Phone You Can Fold in Half

The iPhone vs. Galaxy war just intensified. Samsung is pulling out all the stops and developing a foldable phone dubbed Galaxy X, which it plans to release next year, according to The Wall Street Journal.

It would seem the rumors surrounding a mythical phone that can fold over like a wallet are true. The phone, which has been given the in-house code name “Winner,” will have a 7-inch screen and be a little smaller than a tablet but thicker than most other smartphones.

Details are scant and subject to change at this point, but the phone is expected to have a smaller screen on the front that will remain visible when the device is folded. Business Insider published Samsung patents back in May showing a phone that can be folded into thirds, but the business news site noted that patents often change, and some are scrapped altogether.

The Galaxy Note 9 is also likely to be unveiled soon, as is a $300 Samsung speaker that's set to rival the Apple HomePod.

The Galaxy X will certainly be a nifty new invention, but it won’t come cheap. The Wall Street Journal reports the phone will set you back about $1500, which is around $540 more than Samsung’s current most expensive offering, the Galaxy Note 8.
