5 . When you walk on a sandy beach, it takes more energy than walking down a sidewalk—because the weight of your body pushes into the sand. It turns out that the same thing is true for vehicles driving on roads.
“The weight of the vehicles creates a very shallow indentation in the pavement—and it makes it such that it's continuously driving up a very shallow hill,” said Jeremy Gregory, a scientist at M. I. T...He modeled with his teammates how much energy could be saved-and greenhouse gases avoided—by simply hardening the nation's roads and highways.
And they found that hardening 10 percent of the nation's roads every year could prevent emissions equal to 440 megatons of carbon dioxide over the next 5 decades—that amount is equal to how much CO, you'd spare the planet by keeping a billion barrels of oil in the ground or by growing 7 billion trees for a decade. It reduces 0.5% of projected transportation emissions over that time period.
As for how to harden roads, Gregory says you could combine small amounts of certain fiber with high technology into paving materials. Or you could pave with specially-made concrete, which is harder than ordinary construction materials.
This system could also be a way to shave carbon emissions without some of the usual barriers. “Usually, when it comes to reducing emissions in the transportation department, you're talking about changing policies related to vehicles and also driver behavior, which involves millions and millions of people—as opposed to changing the way we design and preserve our pavements. That's just on the order of thousands of people who are working in transportation agencies.” And when it comes to improving our streets and highways-those agencies are where you might say the rubber meets the road.

6 . Cars could soon be communicating with each other using 5G to make drivers aware of upcoming dangers, scientists claim. The ultra-fast mobile Internet would allow for rapid information transmission and could make drivers aware of black ice, pot holes or other dangers up ahead.
Several car manufacturers are already integrating 5G into their vehicles, including as a tool to welcome the coming of self-driving vehicles. Experts believe the high-speed connection will also improve the reliability and capability of automated vehicles to the point where they will be safer than the manual cars being driven today. They predict the number of road traffic accidents—which according to the World Health Organization (WHO) account for more than 1.3 million deaths and up to 50 million people injured worldwide every year—will drop thoroughly as a result.
Dr Dimitrios Liarokapis, a member of the research group, said: "With the help of 5G, an early warning system that alerts (给……报警）drivers is possible within the next few years. Cars that are close enough to the danger area will send warning messages to other cars around them using short-range communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will transmit the same information to cars near them and so on, forming a joined-up, multi-vehicle communication chain that stretches far and wide."
Automotive giant Ford is already working on connected cars. Earlier this year it revealed its intention to fit 80 percent of its 2020 vehicles with technology that warns drivers about upcoming road accidents, bad weather and traffic jams. The system pools data from other connected road users, emergency services and the authorities and sends it from the cloud directly to the car. Alerts are shown on the car's dashboard display warning the driver about what lies around the corner.

7 . To get from New York City (NYC) to Chicago, there are several transportation options. Consider the pros and cons of each option to choose the best one for you.
Time | Cost | Best for | |
Train | 20 hours | from $70 | seeing scenery |
Flight | 3 hours | from $48, but varies widely | getting there quickly |
Bus | 19 hours | from $38 | travelers on a budget |
Car | 12 hours | from $60 | stopping for attractions |
By train
Traveling by train from NYC to Chicago is a relatively long journey. Trains go from Penn Station in Manhattan to Union Station. The route is serviced by Amtrak, via the Lake Shore Limited or Cardinal to Chicago or by changing trains either in Washington, D. C. or Pittsburgh. You can purchase tickets in advance by Amtrak or in person at Penn Station.
By plane
Flying to Chicago is the fastest and most convenient way to travel there from NYC. The major carriers include JetBlue, Delta, United, and American Airlines, as well as budget carriers including Southwest and Spirit Airlines.
