中国内地31城开通轨道交通 53城开工建设

As of the end of June, 31 cities on the Chinese mainland had urban rail transit in operation, with a total length of 3,965 km, according to the China Association of Metros.

中国城市轨道交通协会称，截至今年6月底，中国内地已有31个城市开通运营城市轨道交通，运营总里程达3965公里。

Another 53 cities have started building rail transport facilities, with a planned construction length of over 9,000 km. About 5,770 km is under construction.

另有53个城市已开工建设轨道交通设施，规划建设规模超过9000公里，在建规模约5770公里。

"Urban rail transit on the Chinese mainland has seen rapid development for more than 10 consecutive years," said Zhou Xiaoqin, executive vice president of the association.

该协会常务副会长周晓勤说道：“中国内地的城市轨道交通已连续快速发展10年以上。”

He said this year the length of urban rail transit in Beijing and Shanghai both surpassed 500 km.

他表示，今年北京、上海的城市轨道交通规模双双突破500公里。

Together with Guangzhou, their urban rail transit systems carry more than 50% of the total passenger volume of public transportation.

北京、上海和广州的城市轨道交通系统承担的客运量占公共交通总客运量的比例均超过了50%。

Urban rail transit will continue to be a priority of the country's urban infrastructure construction over the next few years.

未来几年，城市轨道交通仍将是我国城市基础设施建设的重点之一。

It is estimated that the total length of Chinese urban rail transit in operation will reach 6,000 km in 2020, Zhou said.

周晓勤称，据预计，2020年全国城市轨道交通运营总里程将达6000公里。
