Railway, expressway and air traffic flows in China still remain high as a travel rush triggered by millions of travelers returning from their hometowns is sweeping the country.

Some 30,000 railway trips are expected to be made on Friday at the newly-built Chongqing Xi Railway Station, with an additional two pairs of shuttle trains running northbound, with the aim of saving on transfer time for passengers.

The railway authorities in Jinan City, capital of east China's Shandong Province, have increased the passenger capacity of the busiest trains with adding an additional 550,000 seats for the trains heading to metropolises such as Beijing, Tianjin and Shanghai.

On expressways, long lines of vehicles were seen across the country on Wednesday, the last day of the toll-free dates for the Spring Festival.

More than 690,000 vehicles were recorded passing through the toll gates of Kunming City, capital of the country's southwest Yunnan Province, an increase of 0.7 percent year on year.

The massive traffic flow led to a large congestion early on Friday morning with the expressways becoming clear on around midday.

A total of 11.4 million plane trips were made from Feb 15 to Wednesday during the Spring Festival holiday, up 16.1 percent from the same time period of last year, according to the Civil Aviation Administration of China.

This year's flight punctuality rate has also improved, stood at 90.95 percent with a 6.1-percent points rise.

Airports at popular tourism destinations like Haikou, Lijiang, and Harbin were busy as many Chinese holidaymakers chose to travel domestically.

Hundreds of millions of Chinese went back to their hometowns with their families to celebrate the Chinese Lunar New Year, which fell on Feb 16.

The annual travel rush around the festival, known as "chunyun", often puts the transport system to test.
