Chongqing has surpassed Beijing as the most congested city in China, according to a report made by China's biggest car-hailing app Didi Kuaidi, using its Internet-based big data analysis.
In its first ever China Urban Smart Transportation Report released on Wednesday, Didi Kuaidi ranked Chongqing as the country's most congested city, followed by Qingdao and Guangzhou, beating the megacities like Beijing and Shanghai, Beijing only came in the fourth place while Shanghai finished the eighth.
Analyzing its 1.43 billion rides by its 300 million app users in 2015, Didi said traffic congestion has already spread to China's second- and third-tier cities amid the country's rapid urbanization and car purchases wave.
