Golden Traffic--Analysis Report of Major Urban Traffic in China

The report of China's major cities'congestion ranking is based on the massive traffic trip data accumulated by Gaode. It is calculated by big data mining, and its rationality and scientificity are guaranteed by the general algorithm and theory. The report uses the "congestion delay index" as the evaluation index of urban congestion degree, that is, the ratio of the actual travel time of an average trip of urban residents to the travel time of free flow.

China's urban traffic analysis report uses "congestion delay index" as the evaluation index of urban congestion degree, that is, the ratio of the actual travel time of an average trip of urban residents to the travel time under free flow. From the perspective of travelers, the index expresses the time cost of traffic congestion to travelers in a simple and understandable way. This report objectively reflects the traffic congestion situation in cities from multiple dimensions, striving to be accurate, precise and accurate, and provides valuable theoretical reference for public transport travel, institutional research and government decision-making.
