BEIJING, Dec. 23 -- China's transportation system will carry a record number of passengers during the upcoming "Chunyun," peak travel period around the Lunar New Year Festival.

Up to 2.91 billion trips are expected to be made via road, railway, air and water between Jan. 24 and March 3 in the annual migration, up 3.6 percent year on year, said the National Development and Reform Commission (NDRC), the country's top economic planner.

The NDRC asked related agencies to prepare for extreme weather conditions to guarantee safe and smooth traveling and to use technology to improve services.

This year Lunar New Year will fall on Feb. 8.

The world's largest human migration, the travel spree will see millions of people traveling home to see their families.
