It is the second time that Jinan surpassed Beijing to be the most jammed city since the third quarter of last year, according to a report compiled by map service provider AMAP and a transport research center attached to the Tsinghua University.

该报告由地图服务提供商高德地图联合清华大学下属的某交通研究中心编制。报告称，这是济南继去年三季度之后，再次超越北京成为第一"堵城"。

Other top 10 of most congested cities include Harbin, Chongqing, Zhengzhou, Shenzhen, Guiyang, Kunming and Guangzhou.

其他进入"堵城"排行榜前10的城市有：哈尔滨、重庆、郑州、深圳、贵阳、昆明和广州。

济南超越北京 再成我国首堵城市

Traffic congestion eased greatly during the first quarter, as large numbers of people working in cities traveled back to their hometowns to celebrate the spring festival, AMAP analyst Fang Yiduo said.

高德地图分析师房一多表示，由于大量在城市工作的人回到自己的家乡共度春节，所以在第一季度大城市的交通拥堵情况大大缓解。

First-tier cities including Beijing, Guangzhou, and Shanghai see congestion reduce by 40 percent during the same period, Fang added.

房一多补充说道，包括北京、广州和上海在内的一线城市在同一时期拥堵情况降低40%。

In terms of speed, the average speed in rush hours in Jinan was slightly over 20 kilometers per hour.

在速度方面，济南高峰时段的平均时速略高于20公里每小时。

Hong Kong performed well with a traffic speed of nearly 30 km per hour in rush hours thanks to its advanced transport infrastructure and high proportion of highway.

得益于先进的交通基础设施及高比例的高速公路，香港在交通流动速度方面表现良好，在高峰时段大约为30公里每小时。
