Metro systems are designed to transport masses faster and efficiently. They link residential areas, cities, airports, and suburban areas. Fifteen of the twenty-five metro systems constructed in the five years leading to 2019 are located in China. The rapid growth of metro systems in the country is necessitated by the large population and the need to move masses faster without creating traffic jams. These are the newest subway systems in the world. The Jinan Metro, Wenzhou Metro, and Noida Metro were all opened in January 2019.
