Sanya tops China's reliability in transports in 40 major cities
Didi Chuxing (滴滴出行), China’s largest taxi-on-demand platform, recently released an analysis report of the reliability of transportation in China’s 40 major cities.
Sanya comes out on top with the most reliable transportation network in China, followed by Suzhou, Weihai, Quanzhou, and Tangshan. Harbin, Changchun, Jinan, Shijiazhuang, and Lanzhou were at the bottom.
China’s four largest cities — Beijing, Shanghai, Guangzhou, and Shenzhou — were ranked 22nd, 26th, 27th, and 28th respectively.
The report analyzed Didi Chuxing’s big data and developed a series of quantitative indicators to measure traffic reliability.
For example, in Beijing, most of the time, a taxi trip is considered to be one that travels on average 1 km every 2.83 minutes. However, average travel times in congested areas of the city or during rush hour can be as long as 4.94 minutes per km. Therefore, for residents in Beijing, they need to reserve at least 2.11 more minutes per km to ensure that they can arrive at their destination on time.
The report points out that to reach a destination on time, a commuter needs to reserve only 1.33 more minutes per km than average travel time in Sanya, while in Harbin, a commuter has to reserve at least 2.89 more minutes per km in order to arrive at the destination on time.
