Beijing topped the traffic congestion list of 45 major domestic cities in the second quarter, and the frequent use of ride-hailing services was cited in a report as a major reason.

Commuters in Beijing spent on average 32 minutes per hour in traffic jams while traveling during rush hours, said a report released on Tuesday by AutoNavi Software Co, a mobile web-mapping service provider.
