4 . The 2023 China-Germany Automobile Conference was held in Jilin, Henan, and Zhejiang recently. At the conference, people discussed plans for new energy vehicles (NEVs) and collaboration (合作) between Germany and China.

China has established a competitive edge in NEVs. In 2022, China’s market share of NEVs accounted for more than 65 percent of the global total, maintaining its position as the world’s leading NEV market for eight years, China Daily reported.

Reflecting on the journey of leading Chinese electric car manufacturer (制造商) BYD, Chairman Wang Chuanfu recalled about 2003 when BYD entered into the NEV industry amid doubts and mockery, as few people back then believed in the future of NEVs. Surprisingly, within a few years, China’s NEV exports increased greatly. In 2022, the China Association of Automobile Manufacturers reported an impressive total export volume of 679,000 NEVs.

In the European market, Chinese brands, such as BYD and Hongqi, have entered the top 50 best-selling motor companies across Europe, The Times reported. Shu Youxing, general manager of BYD International Cooperation Division and the European Automobile Sales Division, said that the company’s pure electric buses have now hit the roads of more than 100 major European cities such as Amsterdam, London, and Copenhagen, helping Europeans cut carbon emissions by over 200,000 tons.

NEVs made in China are also popular in Mexico. One local, Israel Aguilar, is deeply impressed. After nearly a year of trying out a Chinese NEV, Aguilar said he may never go back to driving his traditional petrol car, stating that the NEV offers better comfort.

“Technology is truly very important in these times, especially for a vehicle. And it has been truly extraordinary for me to handle these technologies that come from China,” Aguilar told Xinhua.

The thriving global expansion of Chinese NEVs is primarily thanks to the efforts of companies to improve their capability for innovation. One major example of this is China’s drive to become the global leader in making EV batteries, fueled by an advantage in the supply chain and raw materials such as lithium (锂) and cobalt (钴).

5 . 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.
