Commuting to and from work can be a nightmare. Cars advance slowly in stop and go traffic, crawling from one traffic jam at stoplights to the next. At peak rush hour especially, there is no chance of sailing through a series of green lights. Now, thanks to artificial intelligence, German researchers have found a way to reduce time spent at the crossroads.

Called the KI4LSA project and funded by the Ministry of Transport and Digital Infrastructure, the innovation is being tested. Scientists first studied algorithms taken from a busy intersection to learn about traffic patterns and where improvements were most needed. Then, the technology, using high-resolution cameras and radar sensors, more precisely captured the actual traffic situation and detected the average speed of the cars and their waiting times. Finally, the AI uses deep enhanced learning algorithms to calculate the best switching behaviour for the traffic lights and determine the best phase sequence to shorten waiting times at the crossroads.

The results are encouraging when it is being tried out at a busy intersection in Lemgo, Germany. The intelligent lights are said to improve traffic flow by 10 to 15 percent, which results in money saved; the EU estimates that traffic jams create economic damage that adds up to 100 billion euros a year. Aside from reducing commuting time, these traffic lights will reduce noise and CO2 emissions from cars waiting at the crossroads.

Another exciting development in this research is the K14PED project, which studies pedestrians crossing the crossroads. Using AI as well as a 3D points cloud, researchers can identify how many people are waiting at a pedestrian crossing and whether some of the disabled or elder people will need extra time to cross the street. Such a needs-based system could reduce pedestrian waiting time by 30 percent, which could then decrease jaywalking (乱穿马路) by 25 percent.

Researchers are optimistic that it will be adopted by many countries after the tests in the German towns of Lemgo and Bielefeld. This technology is exciting news for pedestrians and drivers alike. It encourages safety, protects the environment, and may even give you more time to enjoy your morning coffee before heading off to work!

1. Why is AI used in the KI4LSA project?
A.To study traffic algorithms to control CO2 emissions.
B.To detect road conditions to reduce jam or speeding.
C.To remind people to pass in sequence for a shorter wait.
D.To adjust traffic signals to ensure efficiency at the crossroads.
2. Which of the following is true according to the passage?
A.The intelligent lights serve the mere purpose of reducing commuting time.
B.The better traffic flow is improved, the less economic damage is caused.
C.The more cars are waiting at the crossroads, the more noise is reduced.
D.The effect of traffic jams is heavier on environment than on economy.
3. What is the function of K14PED project?
A.It monitors traffic conditions at intersections.
B.It helps to estimate the number of jaywalkers.
C.It ensures flexible crossing time for pedestrians.
D.It improves the speed of vehicles on busy roads.
4. What is the main idea of this passage?
A.The intelligent lights offer a blessing to transportation.
B.The AI technology is bound to be a promising industry.
C.Attentive traffic service lends a helping hand to seniors.
D.Digital traffic systems mark the beginning of smart cities.

【推荐1】Thanks to high-speed rail, the travel time between major cities in China has already been reduced to only a few hours, making travel within China much more convenient, both for Chinese citizens and travelers from overseas. This convenience in turn should accelerate development within China, as the time and expense of long-distance transportation has been greatly lowered. Without doubt, it will also bring the people of the country closer together, and in time bring about deep social changes, the full nature of which no one can fully guess.

Now that China has gained skill and knowledge in high-speed rail, it is seeking to export its technology to other countries. Its first venture on the international market was the development of a new high-speed rail line connecting Istanbul with Turkey’s capital, Ankara, 530 kilometers away. This was followed by projects in Saudi Arabia, Hungary and Serbia, Thailand, and Indonesia, among other countries. Perhaps its most ambitious project is a Trans-Asian network linking China with Europe, which is hoped to be completed by 2030 as a part of China’s Belt and Road Initiative. Already, China has agreed to build a 762-kilometer high-speed rail line in Russia linking Moscow to Kazan.

While rail travel between China and Europe has been possible for over a century with links to the Trans-Siberian Express, the lime involved has made it impractical. For instance, from Beijing to Moscow alone it takes more than a week traveling by train. However, using high-speed rail, the time from Beijing to London could potentially be cut to two or three days, making high-speed rail a fast and cost-efficient way to travel between China and Europe.

1. What directly makes traveling within China more convenient?
A.Social changes.B.High-speed rail.
C.Lower expense.D.Technology development.
2. Which word can best describe the international market of China’s high-speed rail?
A.Promising.B.Convenient.
C.Impractical.D.Adventurous.
3. How is paragraph 3 developed?
A.By giving examples.B.By sharing experience.
C.By making explanation.D.By making comparison.
4. What is the author’s attitude to China’s high-speed rail?
A.Positive and content.B.Indifferent and neutral.
C.Favorable and confident.D.Negative and concerned.

【推荐2】China Merchants Bank Co Ltd has teamed up with ride-hailing major Didi Kuaidi to provide automobile financing and expand its reach in China's booming mobile payment industry.
The two have inked a comprehensive partnership, which includes a strategic investment by the former in the latter. Under the partnership, CMB will become the first bricks-and-mortar bank that can offer in-app credit card payments to Didi users. At present, users of Didi can only choose third-party payment solutions like WeChat Payment and Alipay to pay cab fares.
Zhao Ju, vice-president of CMB, said the cooperation with Didi was an important step in its mobile Internet finance strategy. “CMB's mobile payment is going to enter a new chapter by leveraging Didi Kuaidi's vast user base," he said.
According to a report by China Internet Network Information Center earlier this month, Didi holds 87.2 percent of China's private car hailing market. The company said it has received 1.43 billion car-hailing requests on its platforms in 2015, which means 1.43 billion payments were made via smartphones.
CMB is expected to use Didi to reach the core users of China's mobile payment market. Jean Liu, president of Didi, said many of the expats prefer payment by credit card rather than Alipay or WeChat. "The new partnership will help improve service quality and customer loyalty," she said. The investment makes CMB part of Didi's existing investors, including Tencent Holdings Ltd, Alibaba Group Holding Ltd and China Investment Corporation. Both of the companies declined to reveal the actual amount of the investment.
Liu, who showed up on Tuesday for the first time in public after her treatment for breast cancer, said the cooperation with CMB is for the long run and "the capital investment is only part of it".
Under the partnership, CMB and Didi will cooperate on a wide range of initiatives on financial services and online-to-offline cooperation. Apart from the in-app credit card payments, the two companies are going to launch joint credit cards in late February and automobile financing services for Didi's car owners. CMB's branches across China are expected to help Didi recruit more drivers.
"There is a lot of room for imagination in our partnership," Li said, adding in future people may use their CMB credit card reward points to pay for the ride on Didi.
Li Chao, an analyst with iResearch Consulting Group, said the partnership may not significantly boost CMB's mobile payment business. "Didi has educated the market for three years and its customers have formed the habit of paying by WeChat or Alipay. So I think CMB can only turn a very smart proportion of Didi users into its payment customer," he said. "But the move shows that China's traditional banking industry is finally thinking out of the box and looking for outside partners in Internet finance competition," he said.
Statistics from Big-Data Research showed that more than 90 percent of China's 9.3 trillion yuan ($1.41 trillion) worth of third party mobile payment market is donated by Alibaba and Tencent.
1. Which of the following sentences is true about Didi Kuaidi ?
A.The users of Didi can pay cab fare in cash.
B.At present, Didi holds the largest market of China's private car hailing business.
C.With several years of development, the users of Didi have abandoned the third-party payment.
D.CMB will become the most important investor of Didi.
2. Which of the following is not the purpose of CMB’s cooperation with Didi? .
A.CMB is expected to use Didi to reach the core users of China's mobile payment market.
B.Through the cooperation with Didi, CMB will help improve service quality and customer loyalty.
C.CMB will launch joint credit cards with Didi to expand its service.
D.CMB will turn a very large proportion of Didi users into its payment customer.
3. What can be inferred from the passage?
A.CMB's mobile payment is going to enter a new chapter.
B.China's traditional banking industry is facing fierce Internet finance competition.
C.CMB and Didi will have a online-to-offline cooperation.

【推荐3】You’re stuck in a sea of standstill traffic when it begins: hunger pangs, the kind that release a steady stream of fast food fantasizing. With your grumbling stomach growing louder, your options are limited: You can wait a few hours for the roadways to clear or leave your car idling(挂空挡)on the highway while you set off on foot (please don’t do this).

Now Burger King, is betting that hungry drivers will welcome a third option: a direct-to-driver delivery concept the company has labeled the “Traffic Jam Whooper.” Reached by email, Gustavo Lauria, co-founder of the advertising agency We Believers, which developed the vehicle delivery concept, said the new approach allows the burger chain to gain advantage on a time of day in which the city’s terrible traffic typically slows business. “This was an opportunity for Burger King to generate new profits out of those hungry drivers”, Lauria added.

Lauria claims Burger King is the first fast food brand to deliver food to people in the middle of a traffic jam. In Mexico City, the company said, delivery drivers are already receiving an average of 7, 000 orders per day, mostly to homes and offices. To make the traffic jam delivery process possible, Burger Kings Mexico app activates the service after identifying crowded areas in Mexico City during periods of high traffic. Customers can only place an order if the app determines that the driver will be locked in traffic for at least 30 minutes and they are within a 1. 8-mile distance of a Burger King restaurant, the company said.

Early on, Lauria wrote, the act was met with disbelief. The challenges were complex: making sure real-time data of geographic location was accurate enough, and the creation of a hands-free way to take orders on cellphones in a country that has adopted serious punishment for drivers who use cellphones behind the wheel.

Though the company did not offer a timeline, Burger King says it expects to roll out the Traffic Jam Whopper in other overcrowded cities, such as Los Angeles, Sao Paulo and Shanghai.

1. What does the “Traffic Jam Whopper” (paragraph 2) refer to?
A.A proposal intended to ease the traffic jam during peak hours.
B.A practice which allows drivers to have food delivered directly to their cars.
C.A platform which makes it convenient for drivers to order food via cellphones.
D.An association monitoring whether drivers are observing traffic rules strictly.
2. Burger King is launching the Traffic Jam Whopper mainly to ________.
A.promote its business cultureB.make a shift in its sales pattern
C.achieve an increase in its profitD.popularize its business into more cities
3. What can be inferred from the passage?
A.The Traffic Jam Whopper poses a threat to the safety of cyclists.
B.Drivers will be allowed to type on their cellphones during traffic jams.
C.Technological barriers may block the traffic jam delivery process.
D.Drivers can instantly choose to activate Burger Kings app at will.
