2017年哪个城市最堵？

Jinan in Shandong was the most congested city in the country in 2017, said a report on China’s major cities’ transportation in 2017 released by Gaode maps, the research institute of Ministry of Transport, and Alibaba Cloud recently.

据高德地图、交通运输部科学研究院及阿里云近期发布的《2017年度中国主要城市交通分析报告》显示，2017年山东济南是全国最拥堵的城市。

According to the rankings, the other top 10 cities were Beijing, Harbin, Chongqing, Hohhot, Guangzhou, Hefei, Shanghai, Dalian, and Changchun.

据排行榜可知，拥堵城市前10中的另外9个分别为北京、哈尔滨、重庆、呼和浩特、广州、合肥、上海、大连及长春。

Among these 10 cities, Hohhot, Hefei, and Changchun were listed on the top 10 rankings for the first time. Although Jinan was most congested, its congestion level did not change from 2016.

以上10个城市中，呼和浩特、合肥与长春是首次跻身(被列入)前10。尽管济南是最拥堵的，但其2017年拥堵程度与2016年相当。

On the whole, the general congestion condition improved nationwide in 2017. The congestion level fell by 2.45 percent compared to that in 2016, which was almost the same as that in 2015.

总体看来，17年全国的拥堵情况普遍有所改善，与16年相比，拥堵水平下降2.45%，该水平与15年相当。

The congestion level in 51 percent cities declined, 27 percent saw no change and 22 percent reported an increase compared to that in 2016.

同2016年相比，51%的城市拥堵程度有所下降，27%城市无明显变化，据报道称22%的拥堵情况有所恶化。

The month of December saw most congestion both in 2017 and 2015, while in 2016 September recorded worst congestion due to the odd-and-even license plate rule’s implementation in many northern cities.

2015年与2017年都是在12月份最拥堵。而2016年却是9月份的交通最拥堵，因为当时大部分北方城市实行了单双车牌限行规定。

The report also shed light on other traffic conditions: Xi’an had the best effect of the odd-and-even license plate rule; Harbin, Guangzhou, Urumqi, Qingyuan were most congested during morning rush hours, evening rush hours, off-peak hours, and holidays respectively; Jinan had the longest hours of traffic congestion; and Hong Kong had the highest cost of traffic congestion.

该报告也阐明其他城市交通情况:西安实施单双号限行规则效果最佳;哈尔滨的早高峰期全年最堵、广州的晚高峰期最堵、乌鲁木齐的非高峰期最堵、清远的节假日最堵;济南交通拥堵为期最长;香港交通拥堵所耗成本最高。

The congestion-delay index was chosen as the evaluating indicator to measure a city’s traffic congestion level, which objectively and multidimensionally reflected a city’s traffic congestion condition and its treating effect, also could provide valuable evidence for public transportation, institute research and government policies.

交通拥堵指数被作为衡量一个城市交通拥堵水平的评价指标，它客观多维度地反映了一个城市的交通拥堵情况以及它的治理效果，同时能为公共交通，学术研究和政府政策提供有价值的依据。
