【推荐1】China’s future high-speed trains might be self-driving, with a top speed around 600 kilometer per hour and an adjustable interior and entertainment system with high-speed Internet，a senior engineer said on Monday.

Fuxing, which debuted first on the line connecting Beijing and Shanghai, has an operating speed of 350 km/h---the world’s fastest. It now serves a dozen major cities, from Chengdu, Sichuan Province, to Shenzhen, Guangdong Province, according to the China Railway Corporation.

Chinese scientists are developing a new model of Fuxing that can adopt to different track widths and still run consistently at 400 km/h, Ding said, an officer of the corporation.

“These new trains can be used effectively in Russia or countries along the Belt and Road Initiative.”

“The new model will enter service within five years, about the same period needed to create and launch the Fuxing. In the next 8 to 10 years, China will launch a high-speed bullet train that is suspended from a magnetic rail-nearly twice the speed of the one currently operating in Shanghai.” he said.

Chinese engineers also are aiming to make future trains more comfortable, including adding more leg room in all carriages, stronger Internet signals and some high-class seats that might involve adjustable interior and entertainment systems, such as windows that can change color or serve as movie screens.

Artificial intelligence will be included in future trains, using equipment such as scanners that automatically check and deduct fees when passengers board and exit trains without having to deal with tickets.

Trains also will have advanced self-driving systems that can predict abnormal conditions and automatically check slow in case of emergencies. These systems will be finished within three years.

Now, China’s high-speed railway network has extended about 25000 kilometers of track, which makes up about 60 percent of the world’s total, according to the corporation.

【推荐2】Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

Unless otherwise posted, the maximum speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles’ headlights on during the day and some have banned driving while using a hand­held cell phone. Motorcycles cannot share a lane, and safety helmets for motorcycle riders and passengers are necessary.

Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

【推荐3】Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever- increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to changing traffic conditions.
The online economics magazineForbes.comsays traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.
Bui scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers. planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders，reach an accident area faster.
The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.
About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.
The center shares its findings with firefighters, police，Transportation departments and the military. They also share information with universities and transportation company. The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.
Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.
