Beijingers lost as much as 7,972 yuan on average to traffic jams last year, the highest in the country, said a report.

Published by Didi Kuaidi, China's largest ride-hailing application and its partners, the report revealed Beijingers on average spent 52 minutes travelling 19.2 kilometers daily between their home and office.

White-collar workers in China's mega cities - Beijing, Guangzhou, Shenzhen and Shanghai - were those who lost most money to congestion.

The cost ranged between 7,972 yuan and 6,324 yuan per person in the four cities whose residents are among the best paid employees in China.

Research based on data collected on Didi Kuaidi's online platform showed that not only those in mega cities suffered from poor traffic conditions.

The report said residents in second-tier cities spent 37 minutes on average between home and work with a travelling speed of 23 km/h due to congestion. The speed was even slower than first-tier cities' 24 km/h.
