Jinan city has failed to shed its unwanted title as "the most congested Chinese city".

For people living in the capital city of East China's Shandong province, they have to allow an extra 30 minutes during morning and evening rush hours, according to a report on transportation conditions in major Chinese cities in the first quarter of 2017.

The report, released by domestic navigation company Amap, found China's second and third-tier cities are facing increasing traffic congestion, while the problem has eased slightly in first-tier cities.

The report noted a growing number of shared-bicycle riders contributed to the decrease of cars on the roads within 5 kilometers of first-tier cities. The number of car trips made in Beijing and Shanghai dropped 3.8 percent and 3.3 percent respectively in the first quarter.

Affected by downfalls of snow, Hohhot, a third-tier city of North China's Inner Mongolia autonomous region, became one of the top three traffic-clogged cities, with its time-delay index in rush-hour congestion reaching 1.91.

Since coming in as the sixth most congested city, Guangzhou's Shenzhen made big progress in easing congestion this year, as has the previously eighth placed Hangzhou in Zhejiang.

Both cities dropped out of the top 10 traffic hot spots.

Let's take a look at the Chinese cities with the worst traffic so far this year.
