What are the characteristics of the subway? 5. What are the characteristics of the subway?

Advantages: 1. Land saving: Due to the high value of urban land in general metropolises, the railway is built underground, which can save ground space and make the ground land available for other purposes.

2. Reduce noise: The railway is built underground, which can reduce the noise on the ground.

3. Reduce interference: Because the driving route of the subway does not overlap or intersect with other transportation systems (such as surface roads), the traffic is less disturbed and can save a lot of commuting time.

4. Energy saving: Under the problem of global warming, the subway is the best means of public transportation. Due to the stable speed of the subway, it saves a lot of commuting time, makes people happy to ride, and also replaces a lot of energy consumed by driving.

5. Reduce pollution: The general car uses gasoline or oil as an energy source, while the subway uses electric energy, there is no exhaust emissions, and it will not pollute the environment.

Disadvantages: 1. High construction cost: Due to the need to drill underground, the cost of underground construction is higher than that of building on the ground.

2. Long construction period: also due to the need to dig tunnels, lay rails, install equipment and various commissioning work. It takes a long time for the subway to be put into operation from the start of construction.

3. Long pre-production time: The pre-construction of the subway is long, and even tests are required due to the need for planning and approval. It takes a very long time from the beginning of the brewing to the implementation of the groundbreaking, which can be as short as a few years or as long as more than ten years.

The subway has been used as a transportation facility in modern cities for more than 100 years. In 1863, the world's first underground ran in the UK. By the early 90s, more than 200 subways had been built in 88 cities in 39 countries around the world, with more than 50 million people taking them every day.

Why build an underground railroad? Practice shows that the underground railway has the characteristics of fast vehicle speed, many trains, large passenger volume, convenience and comfort. In wartime, the underground railroad was also a good anti-aircraft shelter. Let's take the Shanghai Metro as an example to illustrate the superiority of the subway.

1.It's fast. Shanghai Metro Line 1 has a total length of 13 stations. The subway is more than twice as fast as the bus, and it used to take 1 hour to get there, but it only takes 20 minutes to take the subway.

2.There are many trains. The interval is 2 minutes.

3.The passenger traffic is large, convenient and comfortable. Shanghai metro cars were imported from Germany. Each carriage is 23 meters long and 3 meters wide, and can carry more than 400 passengers. The carriages are looser than the buses, and at peak times, there are 5-6 people per square meter standing, while the buses are 12 people.

The Shanghai metro station is air-conditioned, equipped with closed-circuit television, radio, automatic disaster alarm system, and a department store, which can be said to be a safe and comfortable little world, which can be used as an ideal air defense place in wartime.

Because of all the advantages of the subway, most of the world's major cities have underground rail.

Compared with other means of transportation in the city, the subway has many advantages: first, it has a large capacity, and the transportation capacity of the subway is 7 10 times larger than that of ground buses; Second, the speed is fast, the subway travels at lightning speed in the underground tunnel, unimpeded, the speed is 2 3 times faster than the general ground vehicle, and some can exceed 100 kilometers per hour; Third, there is no pollution, the subway is powered by electricity, and there is no air pollution problem. In addition, the subway has the advantages of punctuality, convenience, comfort and energy saving.

1. Advantages: Urban rail transit has a large transportation capacity.

Urban rail transit has high punctuality.

Urban rail transit has high speed accessibility.

Urban rail transit has a high level of comfort.

Urban rail transit has a high level of safety.

Urban rail transit makes full use of underground and above-ground space.

The operating cost of the urban rail transit system is low.

Urban rail transit has low pollution to the environment.

2. Disadvantages: 1The construction cost is large.

2.The construction period is long.

3.Once built, it cannot be changed.

Advantages of subway: saving land, reducing noise, reducing interference, saving energy, reducing pollution;

2.Disadvantages of subway: high construction cost, long construction period, long upfront time;

3.The subway is a means of public transportation and a public place, so when taking the subway, we should be civilized, observe etiquette, abide by safety norms, and jointly create a good and harmonious riding environment.

Although the subway will not be seen everywhere in my life, but in important cities, the subway is a landmark construction, and the characteristics of the subway are: no traffic jams, fast speed, convenience, and no occupation of surface land resources.

Noise reduction: The railway is built underground, which reduces noise on the ground. Reduced disruption: Because the subway route does not overlap or intersect with other transportation systems, such as at-grade roads, there is less traffic disruption and a lot of commuting time can be saved.

The advantage of the subway is that it can go directly to the destination, which can reduce the time for consumers. It's great to reduce congestion and reduce noise pollution for the whole city, the only bad thing is that you need to spend too much money.

Pros:1Land saving: Due to the high value of urban land in general metropolises, the construction of railways underground can save ground space and improve the ground land.

2.Noise reduction: The railway is built underground, which reduces noise on the ground.

The subway is fast and punctual because it doesn't have to wait for traffic lights and the speed is much higher than that of buses.

Pros:

The metro and other means of transport in the city.

In addition to avoiding congestion on the urban floor and making full use of space, there are many advantages.

1. Large volume. The capacity of the metro is 7 to 10 times greater than that of ground buses, which is unmatched by any means of urban transport.

2. Punctuality, punctuality rate is generally higher than that of buses.

3. The speed is fast, the subway train is moving in the underground tunnel, and the maximum speed is generally 80 kilometers per hour, which can exceed 100 kilometers and even reach 120 kilometers.

Cons:

1. High construction cost: the subway project has a long route and a wide range of influence, and it is usually necessary to demolish, renovate, and protect the structures, pipelines, and roads along the route, and the cost outside the project is relatively large. Most of the subway projects are underground, and the cost of underground construction is higher than that of building on the ground due to the need to drill underground.

Key features: The vast majority of urban rail transit systems.

They are used to transport passengers who commute within the city, and in many cases, the urban rail transit system will be regarded as the backbone of urban transportation. In general, urban rail transit systems are used by many metropolises to solve the problem of traffic congestion.

The metro has taken on the main task of transporting passengers in many cities, the Moscow Metro.

It is one of the busiest metro in the world, with an average of 8 million Muscovites taking the metro once a day, and the metro is responsible for 44% of the city's total passenger traffic. Tokyo Metro.

The operating mileage and passenger traffic are very close to those of the Moscow Metro.

The Paris metro already carries more than 10 million passengers a day. New York has the fifth-longest subway route in the world, with a total of 20 million daily passengers, accounting for 60% of the city's transportation by all modes of transportation. Hong Kong MTR.

Although the total length is only one kilometer, it carries a whopping 2.2 million passengers a day, reaching 2.8 million passengers at its peak.
