In China, with the development of economy, megacities are rising day by day and the urban area is getting larger and larger. So what should be the most effective means of transportation in big cities?
Planes, trains, subways, buses, light rails and other means of transportation that I can’t even think of. If you were the mayor, which one do you think can sort out the traffic quickly and effectively? All internet wizards are welcome to express their opinions. The editor has thought about it for a long time but has not been able to determine an accurate answer because I have no work experience in this area. Haha, you probably know the meaning. But the analysis I saw in the book "China's Urban Megatrends" is very consistent with my thinking. The most obvious symbol of the urban area is the "1-hour traffic circle", which is naturally inseparable from the subway and light rail I just mentioned above. , airplanes, cars and a series of means of transportation. In the metropolitan area mode, Shanghai Metro Line 11 is connected to Kunshan City, Suzhou. Guangzhou has two subways connected to Foshan . Shenzhen Metro will also be fully connected to Dongguan Huizhou in the future. Wuhan's The urban rail will also be connected to , Ezhou, and other places. This alone reflects that if the city wants to expand and develop, cars and airplanes seem to have become individualized. Only behemoths such as trains, light rails, and subways can be installed. of lower city crowds.
Trains have a long history and have limitations in development. They travel long distances to connect every city. However, light rails, like trains, run on the ground. The city's road conditions do not allow so many complicated lines to run on it, so the subway will solve the problem. All questions here. At this moment, the editor also feels that the subway is the most convenient means of transportation for direct person-to-person interaction in the city!
In fact, the development of subway transportation in foreign cities began in January 1863, when the world's first underground railway was completed and put into operation in London, England. From 1863 to 1899, 7 cities in the world built underground railways. From 1900 to 1949, 4 cities in the world built underground railways. After World War II, underground railways developed extremely rapidly. By the early 1990s, more than 80 cities around the world had built underground railways, with a total line length of more than 5,000km.
The advantage is that the subway can be built underground, on the ground or on a viaduct; although the rail weight of the subway is relatively heavy, in order to enhance the stability of the track, reduce the workload of maintenance and repair, increase the return cross-section and reduce stray current, the subway is generally They all tend to use heavy-duty rails, which have the advantage of long service life and relatively strong stability. The most important thing is transportation capacity. The running speed of the subway in one minute is generally -80 kilometers per hour, about 1-1.2 kilometers per minute. The driving speed is quite advantageous and there is no traffic jam. According to existing data, the maximum peak hour passenger flow in one direction of the Beijing-Shanghai-Guangzhou Metro is 30,000-60,000 people. Among the top ten cities in my country by subway passenger volume in July, Nanjing ranked ninth with 72.62 million, Xi'an ranked eighth with 82.06 million, Wuhan ranked seventh with 94.26 million, Hangzhou ranked sixth with 95.03 million, Chengdu ranked fifth with 141.86 million, and Shenzhen Ranked fourth with 163.11 million, Shanghai ranked third with 212.79 million, Beijing ranked second with 232.68 million, and Guangzhou ranked first with 237.04 million.
Beijing, Shanghai and Guangzhou are worthy of being super first-tier cities. Not only are they strong in comprehensive strength, but they are also far ahead in terms of passenger traffic. The three major cities have all exceeded the 200 million passenger mark, and Guangzhou ranks first in the country with an astonishing 237.04 million passengers. It can be seen from this data that the passenger volume of Shenzhen, Chengdu, and Chongqing subways has exceeded 100 million, ranking second in the square. Hangzhou and Wuhan are only one step away from 100 million passengers. With a passenger volume of more than 80 million, Xi'an is the only provincial capital city in the north to be shortlisted. It can be seen from here that if a city wants to be crowded with people during its development, it must be a subway that can give you such a feeling. It also reflects the prosperity and popularity index of a city.
Summary:
Beijing, Shanghai and Guangzhou, as China's window cities, have always been given high hopes by everyone. They are already among the best urban tourist destinations in the world. How far will the subway development in window cities in the future? We look forward to the ingenious infrastructure level of the Chinese people. Maybe in many years to come, Beijing, Shanghai and Guangzhou will become a "one-hour transportation circle" through the subway, and a Chinese super city will be born. I don’t know what everyone thinks about this? Everyone is welcome to leave messages and comments!
