1 . How to charge an electric vehicle (EV) is one of the biggest concerns people have when working out whether going electric is right for them.
It is true that sometimes gaining access to reliable charging can seem a bit tricky.
First, download an app with a comprehensive map of the public charging points showing their locations, how powerful they are, and whether they’re working. All this is vital information because, even if you have public charging points nearby, you will need alternatives in case they’re in use.
A growing number of property owners are renting out their charging points and drive ways to other local EV drivers when they’re not using them.
For now, if charging access remains difficult for you, it’s still possible to go electric-in part.
A.But it may be easier than you think. |
B.It actually worked out much cheaper. |
C.There are also other innovative ways to get your EV going. |
D.A plug-in EV combines a petrol engine with a smaller battery. |
E.A “fast” charger usually takes eight hours to fully charge an EV. |
F.So you need to get a good feel for where your nearest points are. |
G.You can find a map of homeowners whose charging points are available. |

5 . Suspension bridges, with their high towers and elegant spans (跨度), are achievements of engineering. This list covers the longest main spans of suspension bridges around the world, not longest total lengths, as those main central spans are where the real engineering magic happens.
Osman Gazi Bridge, TürkiyeThe Osman Gazi Bridge is a splendid suspension bridge. The bridge was finished on July 1, 2016, and at the time, it was the longest suspension bridge in Türkiye and the fourth longest in the world by the length of its main central span, which measures 1,550 meters. It reduced travel time between Istanbul and Izmir from six hours to around five.
Great Belt Bridge, DenmarkThe Great Belt Bridge connects the Danish islands Zealandand Funen. The suspension bridge has a total length of 6,790 meters and a main central span of 1,624meters, making it the world’s sixth longest main span — for now. It enabled a direct driving route from mainland Europe to Sweden through Denmark.
1915 Çanakkale Bridge, TürkiyeThe bridge’s construction, which began in March 2017 and concluded in March 2022, was ambitious from the get-go. Spanning the historic Dardanelles Strait in northwestern Türkiye, the 1915 Çanakkale Bridge is a symbol of national pride. Officially the world’s longest suspension bridge, it stretches a remarkable 2,023 meters in its main central span.
Yangsigang Yangtze River Bridge, ChinaOpened to traffic in October 2019, the Yangsigang Yangtze River Bridge in Wuhan, Hubei Province, China, is the longest suspension bridge in China and the third longest suspension in the world. It spans 1,700 meters across the famous Yangtze River. The bridge notably has the world’s longest double-level bridge span, accommodating various forms of transportation on its two levels.

7 . Researchers have proposed a novel method for counting and tracking vehicles on public roads, a development that could improve current traffic systems and help travelers get to their destinations faster.
Using the cameras already installed on campus buses at the Ohio State University, researchers proved that they could automatically and accurately measure counts of vehicles on urban roadways, detect objects in the road and distinguish parked vehicles from those that are moving.
In previous studies, Ohio State researchers found that using these mobile cameras provides much better spatial and temporal (时间的) coverage than relying on often temporarily placed sensors that don’t provide a view of many streets and roads in a city.
“If we collect and process more high-resolution (高清) spatial information about what’s happening on the roads, then planners could better understand changes in demand, effectively improving efficiency in the broader transportation system,” said Keith Redmill, lead author of the study.
“If we can measure traffic in a way that is as good or better than what is conventionally done with fixed sensors, then we will have created something incredibly useful extremely cheaply,” he said. “Our goal is to start building a system that could do this without much manual intervention because if you want to collect this information over lots of potential vehicles and lots of time, it’s worth fully automating that process.”
While still a long way from total implementation (实施), the study suggests the system’s results bear promise for the future of intelligent traffic surveillance. Transportation planners, engineers and operators make vital decisions about the future of our roadways, so when designing transportation systems to work over the next 30 to 50 years, it’s necessary that we give them data that allows them to improve the efficiency of the system and the level of service provided to travelers.

9 . Since the 1920s, a little-known policy called parking minimums has shaped many Americans’ life. In major cities, this meant that any type of building needed to reserve a certain number of parking spaces to accommodate anyone who might visit.
But as the country attempts to cut carbon emissions (排放), we should rethink what transportation and public space look like, especially in cities. Earlier this month, the city of Austin, Texas, became the latest community to undo parking minimums.
“If we want half of all trips to be in something other than a car, then we can’t, as a city, in my opinion, demand that every home or business have at least one parking space for each resident or customer,” said Zohaib Qadri, the Austin city council member who introduced the measure. Reducing dependency on cars was a huge push for the initiative in Austin. Qadri hopes the measure also will lead to a more sustainable city.
The undoing of this law could pave the way for cities to build denser (密集的) housing, increase public transit options, and reduce their carbon emissions, according to Donald Shoup, an engineer and professor. “It isn’t just the housing crisis and climate change; it’s a traffic jam; it’s local air pollution; it’s the high price of everything—except parking,” said Shoup.
Climate change and air pollution are particularly costly outcomes, with both estimated to cost the US billions of dollars every year. Parking spots, meanwhile, can run in the tens of thousands of dollars to construct, with one estimate putting that figure at almost $30, 000 per spot.
But undoing parking minimums does not mean that all parking will disappear overnight. It means that any off-street parking built will not need to meet any minimum standard.
“Austin is the same city that it was two weeks ago,” said Shoup. “It’s going to take quite a while for that city to really get the benefits of their parking space reforms. And so it just removes a roadblock and a barrier to other reforms.”

10 . Riding the bus to school could be keeping some kids out of class. Most school buses run on fuel. Those buses send out pollution, including tiny particles and gases. Bus riders get exposed to high levels of this pollution. When breathed in, it can lead to breathing problems, such as asthma (哮喘), which may keep kids home from school. But replacing the worst-polluting buses should cut down on student absences, a new study shows.
The study focused on schools that were asked to take part in a U. S. government program. The program offered schools cash back for money spent on cleaner school buses. The 2, 816 school districts in the new study all asked for the money. But not all got it. Only 383 were picked to receive funding. Winning districts could buy new buses and desert old ones.
The program started in 2012. From 2012 to 2017, the winning districts very likely had less bus pollution. And a year after getting new buses, student attendance had improved in those districts. For an average district of 10, 000 students, about six more students attended school each day in the winning districts. Districts that replaced the oldest buses had an average of 45 more students in school each day.
Those numbers may sound small, but they can add up, says Meredith Pedde, an environmental epidemiologist (流行病学家). Almost 3 million U. S. kids ride school buses more than 20 years old, her team figures. Replacing all of those old buses could mean 1.3 million fewer student absences each year, the data suggest. And school attendance matters for student achievement.
Now the U. S. Environmental Protection Agency (EPA) has a new program for school buses. It’s offering $5 billion through 2026 to replace old fuel buses with cleaner ones. Almost all U. S. school districts can apply for the new rebates. But schools in low-income areas and in rural areas will get priority. Kids in these areas tend to face the most health risks from old buses, EPA notes. And anything that cuts air pollution, Pedde says, should improve student health.
