Special rail services will also ease traffic volume.

Railway authorities will run 80 bullet train trips every day on the Beijing-Zhangjiakou high-speed network to provide commuter services for the Winter Games. Additional train services will be provided during the opening and closing ceremonies.

Railway lines will shuttle participants, including athletes, media representatives and Olympic personnel, to and from the various Games zones.

In order to comply with epidemic control protocols, railway stations, including Qinghe and Yanqing in Beijing, and Taizicheng in Zhangjiakou, are operating separate services for participants in the closed-loop system and regular passengers, until March 16.

Even though Beijing has greatly improved the city's air quality in recent years, efforts to minimize pollution will be further ramped up during the Games.

Residents are strongly recommended to use public transport where possible, while a stricter traffic restriction policy－based on odd-even license plate numbers－will be in place when the air quality is not good enough.

Zheng Kai, a technology employee in Beijing, said it is everyone's duty to contribute to the Winter Olympics, so he will take the subway as much as possible during the Games instead of driving.

"I'm very much looking forward to the Winter Olympics, and hope that the athletes can enjoy the Games and their time in Beijing," Zheng said.

The on-site weather service teams will provide the latest meteorological updates to agencies at the main operation center of the organizing committee. The round-the-clock service will issue traffic-related weather reports, weather warnings and forecasts. The weather team in Yanqing will also pay special attention to forest-fire control and traffic.

The use of 5G technology will facilitate instant updates and communication.

For Beijing 2022 athletes and participants, an immersive 5G experience will start the moment they step into a competition area.

There are about 2,000 base stations in total, including both 4G and 5G, which will provide stable internet coverage across all major venues during the Games, said Cai Kai, general manager of the Network Optimization Center at China Unicom Beijing Branch.
