Didi released its 2017 data on the afternoon of January 8. In 2017, Didi provided more than 7.43 billion trips to 450 million users in more than 400 Chinese cities, excluding trips for bikes and driver services. That is roughly equal to everyone in China using Didi five times in the past year.
In 2017, Didi carpooling and car sharing shared 1.05 billion seats. Didi offered 1.1 billion trips in 2017.
Didi said its most important technologies are machine learning, big data and AI. Didi provided 30 million little green spots (recommended waiting spaces) based on AI technology, and saved 2.1 billion phone calls in 2017. By the end of last year, Didi was more than 85 percent accurate in forecasting travel demand based on its capacity.
In 2017, Didi conducted intelligent transportation tests with many cities, launching smart signals, intelligent guidance screens and tidal lanes. According to Didi data, by the end of 2017, Didi had optimized more than 1,200 traffic lights in Jinan, Wuhan and Guangzhou, reducing the local traffic congestion index by 10 percent to 20 percent.
In addition, Didi also cooperated with the public security department to carry out certificate identification and background screening. In 2017, the Didi platform refused 40,000 non-conforming registration applications every day. Didi unveiled anti-fatigue driving and safety driving monitoring systems, which reduced the traffic accidents on Didi by 21 percent. This rate is lower than the average level of the traffic industry. Through publicizing, education and tips, Didi increased the use of seat belts in the rear seat from 2.5 percent to more than 10 percent.
