As the first rail transit line under construction for the coordinated development of Beijing, Tianjin and Hebei, Beijing Rail Transit Line 22 has officially entered the stage of comprehensive construction.
The total length is 81.2 kilometers, of which the Beijing section is about 51.2 kilometers long and the Hebei section is about 30 kilometers long.
What kind of travel convenience will the opening of this line bring to the residents living in the surrounding areas?
What kind of help has been provided in stimulating economic development?
Beijing-Tianjin-Hebei "on track"
In recent years, the construction of Beijing-Tianjin-Hebei rail transit has advanced rapidly.
The Jingtang and Jingbin intercity railways planned to be completed within this year have entered the stage of operational testing.
In addition, the Beijing-Zhangjiakou high-speed railway and the Beijing-Xiong intercity railway have been opened. What kind of promotion effect has the basic formation of the "one-hour traffic circle" in the core area of Beijing-Tianjin-Hebei brought to the development of the Beijing-Tianjin-Hebei region?
Beijing Rail Transit Line 22 integrates multiple modes of operation
Yang Liming, Director of the First Track of the Beijing Major Project Construction Command Office: At the beginning of planning and design and from the perspective of construction and operation, practical problems were considered.
We have integrated a variety of operation and organization methods, including fast and slow train operation, asymmetrical departure, and the organization method of multi-crossing operation.
①Departure of fast and slow trains: For example, in the morning rush hour, everyone is in a hurry. If you want to enter the city as soon as possible, you can only stop at 7 stops, and you can get there in 49 minutes.
If you are in the off-peak period, you can stop at the station and get down the whole line for 72 minutes.
②Asymmetric departure: For example, in Pinggu, there are relatively many people entering the city, so the time must be considered, such as stopping at 11 stations and entering the city in 55 minutes.
When we get off work, we make 7 stops and can go home in 49 minutes.
③Multiple crossing road operation: multi crossing road operation means that three crossing roads are set up, and three sections can be turned back.
In Pinggu, usually the passenger flow is relatively small, so there is no need to drive so intensively, and the bus runs every 10 minutes, which can reduce costs.
In Yanjiao, the passenger flow is very dense, and it is necessary to ensure a 3-minute departure interval to pull people away, which can also reduce the effectiveness.
The operating efficiency is improved through various operating modes, which can also meet the overall operating needs.
What does it mean that the Beijing Pinggu Line has connected and transferred with many rail transit lines in the city?
Fang Hengkun, Deputy Chief Engineer of Rail Transit at Beijing Municipal Engineering Design and Research Institute: Beijing Rail Transit Line 22 is actually the first rapid rail transit line newly built in Beijing to serve commuters. A lot of research and thinking.
In fact, what Line 22 proposes is an efficient, convenient and three-dimensional rail transit network constructed through the concept of multi-network integration.
After converting a single line into network operation, passengers along the line can reach Beijing's Zhongguancun, Changping, and the three major science cities in Huairou through one transfer.
When transferring on the same platform as the S6 line at the sub-central hub, it takes 15 minutes to arrive at the T3 terminal, and 35 minutes to arrive at Daxing International Airport.
In addition to the concept of rail network operation, there is actually another innovation point on Line 22, that is, the system system and power supply method adopted by Line 22 are consistent with the railway technical standards, so that we can provide a better foundation for our future rail transit network. The interconnection with the railway network creates favorable conditions.
What kind of assistance will the construction of the Beijing Pinggu Line provide in stimulating economic development?
Fang Hengkun, Deputy Chief Engineer of Rail Transit at Beijing Municipal Engineering Design and Research Institute: In fact, the Pinggu Line is the first demonstration line in Beijing to realize the joint development of rail and land through guiding industrial planning and layout.
In 2020, Beijing proposed for the first time to realize the intensive use of land through the construction of rail micro-centers, and then promote the high-quality development of the city.
Under the guidance of the Beijing Municipal Planning Commission, the Pinggu Line project team has successively carried out integrated research at the line level, station level, and engineering level. Through this research design, the effective agglomeration between the track micro-center and the land has been realized. .
Through this process, we have reintegrated the industries along the Pinggu Line, including the CBD, Tongzhou Sub-center, Yanjiao Economic Development Zone and Pinggu New City.
Through the linkage between land use planning and industry, the reunion of industrial functions has been realized.
Under the background of the integrated construction of rail transit, the construction intensity around the micro-center stations along the line will become higher and higher, the traffic will be more convenient, and the supporting services will also be enhanced, which will eventually attract more and more enterprises to settle in , and finally realized the redistribution of industries.
Similarly, we will also lay out some residential land along the track, so that the corridor along the track will achieve a gradient balance between population and jobs, and finally achieve a high degree of integration between the track and the city.
