In recent years，China’s urban rail transit engineering construction has developed rapidly. By the end of 2019，56 cities in Chinese mainland city had built 6902.5 km of construction lines，an increase of 8.3% over the same period last year. China’s urban rail transit projects，both in terms of construction speed and construction scale，have surpassed other countries in the world，and have become the world’s largest rail transit construction market. The scale of planned and under construction lines has steadily increased，and the annual completed construction investment has reached a record high. This report combs the basic situation of rail transit construction industry development in 2019，and summarizes the development characteristics of mature equipment technology level，full urban rail transit planning mileage，and continuous growth of construction scale. It is pointed out that the travel quality is not high，the flow efficiency is not good，and the design difficulty is increased. The development suggestions are put forward from the aspects of humanized design，improving efficiency，paying attention to safety，implementing intelligent construction and strengthening information construction.
