Answering the current situation and future trend of urban rail transit development From 2013 to 2020, the length of urban rail transit operating lines in China has increased year by year. By the end of 2020, a total of 40 cities in Chinese mainland had opened urban rail transit operations, with operating lines reaching kilometers. From 2013 to 2020, the operating lines of urban rail transit showed an upward trend.
In 2020, there will be 36 new urban rail transit lines in China, with a total of 247.
It is expected to exceed 95,000 by 2025. The rapid accumulation and growth of urban population is the key factor to promote the construction of urban rail transit, and it is expected that there will still be a large market space for rail transit in major cities in China in the next five years. In the future, the purpose of applying intelligent technologies such as informatization, big data analysis and artificial intelligence (AI) to the urban rail transit industry is to make its management more efficient and reduce costs while improving its operation, maintenance, safety and service levels.
This will increase the safety, availability and reliability of the system. Realize networked operation scheduling. Collect multi-source passenger flow monitoring data and build a smart passenger flow analysis and advanced system.
Improve the level of automatic detection and diagnosis of mechanical and electrical equipment, vehicles and rail facilities, and promote the maintenance of equipment and facilities from "fault repair" and "planned repair" to "state repair" and "first-class repair". It will also realize the intelligence of safety and security work. Realize the convenience and humanization of services.
At present, the sustainable development of urban rail transit mainly focuses on reducing energy consumption in the operation process.

With the deterioration of traffic conditions in many cities, public transportation, especially rail transit construction, has received attention at all levels. According to the existing plan, during the "12th Five-Year Plan" period, the average travel share rate of public transportation in all cities across the country will be significantly higher than that at the end of the "11th Five-Year Plan", and large cities with conditions will be encouraged to develop efficient railways.
At present, China's urban rail transit construction is ushering in a period of development. With the increase of investment quota, urban rail transit construction will become a new investment hotspot after large-scale railway investment, and a new growth point for infrastructure investment in the "Twelfth Five-Year Plan". As China's rail transit is gradually entering a stage of steady, orderly and rapid development, the role of the rail transit industry in promoting the national economy has gradually emerged.
According to the "2015-2020 China Urban Rail Transit Industry Market Prospect and Investment Strategic Planning Analysis Report" released by the Prospective Industry Research Institute, the length of China's urban rail transit operating lines increased year by year, with a compound annual growth rate of . In 2013, it was 2,408 kilometers, a year-on-year increase.
And the average length of a single line is increasing overall, from kilometers in 2010 to kilometers in 2012. In 2013, the length of flat roads was kilometers, a decrease from the previous year.
According to the analysis of the rail transit industry report of the Prospective Industry Research Institute, subway construction dominates the construction of rail transit in China. From 2010 to 2013, the operating mileage of China's subway increased year by year, and the proportion of urban rail transit increased.
In 2013, the operating mileage of the subway was 2,050 kilometers, accounting for the proportion of urban rail transit.
In terms of passenger traffic, the market share of urban rail transit passenger traffic has also increased. From 2009 to 2013, the proportion of bus passenger traffic in China's urban passenger traffic has declined, but the market share has always been above 60%. Taxi ridership has been declining overall, in 2013, but to a lesser extent.
The proportion of passenger traffic in rail transit is on the rise, reaching in 2013, but the market share is still small. The market share of urban passenger ferries is relatively small and declining year by year, only in 2013.

In the early 1990s, some large and medium-sized cities in China began to plan the construction of urban rail transit facilities, due to the weak manufacturing capacity of domestic urban rail transit equipment at that time, the vast majority of equipment needed to be imported, which was very expensive, so that the investment and operating costs of urban rail transit facilities remained high, and many cities could not afford it. Therefore, in 1996, a notice was issued to suspend the construction of urban rail transit facilities. In 1999, in accordance with the instructions, the former State Planning Commission took the lead in organizing the implementation of the localization of urban rail transit equipment, and at the same time launched a number of urban rail transit facilities construction projects, the premise is to increase the proportion of equipment localization, vehicles, signal systems and other key equipment to domestic production and supply.
The former State Development Planning Commission adopted a series of strong policies and measures to regulate and control the import of equipment, support domestic production enterprises to engage in localization, and required that the comprehensive localization rate of equipment required for urban rail transit projects should not be less than 70%, and the localization rate of vehicles and signal systems should not be less than 70% and 60% respectively.
Since 2004, China's urban rail transit equipment manufacturing industry has developed rapidly. The comprehensive localization rate of urban rail transit facilities has basically reached 70%, the independent design and production of Type A and B vehicles, the independent production of aluminum profiles for large car bodies, and the localization of braking systems, traction transmission systems (VVVF), automatic fare collection systems and other products have also made progress to varying degrees. After the localization level of equipment has been improved, the technical level of equipment and the construction and operation level of urban rail transit facilities have also been improved, and the investment and operation costs of equipment and urban rail transit facilities have been greatly reduced.
The weak link of the localization of urban rail transit equipment is system integration, product development and the promotion and use of localized equipment, etc., the difficulty of localization is the signal system, traction transmission system, automatic fare collection system, coupler buffer system, etc., the localization rate of these products is low, domestic enterprises generally do not master the core technology or assembly technology, and the user unit is generally inclined to use foreign products. In the next stage, new policies and measures will be adopted to further promote the localization of urban rail transit equipment in view of the weak links and difficulties of localization.
The major of rail transit transportation management is a characteristic major that has only emerged in the last decade. At present, the development of rail transit is not very mature, and it is estimated that this major in China has been good for employment in the past ten years. No matter what major, as long as you learn well, you will be able to get a job. >>>More
