What convenience does the opening of the subway bring to you?

The opening of the subway shortens the distance between cities, which is a blessing for people who get motion sickness on the bus, and the subway is fast and convenient to travel.

First of all, it is convenient to go home, every time I go home, take the subway for 30 minutes to the station, and when there is no subway, it really takes 1 o'clock to take the bus, which is called a slow, and secondly, it is convenient to go to the train station. And then go out to travel also.

The opening of the subway really brings a lot of convenience, for example, if you go out to play here, you can reach the city in ten minutes, no need to take a bus, and you don't need to take a taxi.

The most convenient thing about the opening of the subway is that you don't have to be afraid of being late. I can just follow the pre-arranged time, but sometimes it is very crowded, which is not particularly acceptable to me.

It relieves the pressure of public transportation, and at the same time, the speed is faster, the fare is more reasonable than that of taxis, and the environment is more comfortable, which has become the preferred way to travel to work.

The opening of the subway has made my life easier. No more traffic jams. And it's also very cheap to get closer. I really think it's very good.

I think it's very convenient to do the subway, and I won't waste time on the road, because there will be no traffic jams.

There is one more way to get around, and the number of vehicles on land is greatly reduced, creating a good air environment for going out for exercise.

After the opening of the subway, it can alleviate the traffic pressure, not traffic jams, and give office workers a good travel choice, and it is also hoped that the construction of the Baotou subway in Inner Mongolia will resume as soon as possible.

The advantages of the subway are obvious, with large capacity, fast speed, many shifts, and no traffic jams. However, the subway in some places is a little slow, and it is not as fast as the cars on ordinary roads, which is a bit wasteful.

In the past, it took more than 40 minutes to go to the Big Wild Goose Pagoda by bus, and it was an hour if there was a traffic jam, but now Metro Line 3 has opened, and it takes about 10 minutes to go to the Big Wild Goose Pagoda (**

Comfort, speed, speed, potency.

Legal Analysis: The construction of the subway must meet four conditions:

1.The local government generally pre-calculates the revenue of more than 10 billion yuan;

2.GDP reached more than 100 billion yuan;

3.The total population of the city is more than 7 million, and the population of the urban area is more than 3 million;

4.The passenger flow scale of the planned line has reached a one-way peak of more than 30,000 people per hour; In addition, it must be networked, and a single line cannot be approved.

Legal basis: "Railway Law of the People's Republic of China" Article 3 The competent railway department shall be in charge of the national railway work, implement a highly centralized and unified command of the national railway transportation management system, and guide, coordinate, supervise and help the local railway, special railway and special railway line.

1. The subway will not be congested. The time from home to work can be clearly determined. When there is no subway, if we want to go from one place to another, whether we drive or take a taxi or take a bus, the time is uncontrollable.

Vehicles on the road, such as cars, are particularly prone to traffic jams. This makes it impossible to accurately estimate when we will arrive at a certain place, so we often need to leave 1 or 2 hours in advance, but after the subway is not brought and then need to do this, we only need to be half an hour in advance or 15 minutes in advance. That's the first benefit of the subway.

2. Reduce environmental pollution. Vehicle exhaust fumes are now an important air pollution**. When the subway reaches every corner of the city, people basically don't have to drive anymore.

When most people in the city use public transportation such as subways or buses, the congestion on the road will also be reduced, and the exhaust emissions will be controlled, reducing environmental pollution.

3. Subways generally run underground. Does not occupy ground level traffic space. Moreover, you can ride many people at the same time, and more importantly, the safety of the subway is much more generous than driving on the road.

When we drive on the road ourselves, we often need to pay attention to the battery car that suddenly bursts out of the roadside and the pedestrians who suddenly pass by. But we don't need to worry about these things at all when we take the subway, because the subway traffic environment is generally single and stable. Bright.

1.The average speed of the subway does not seem to be counted, and the speed of each station and each station varies depending on the length of the station, the ramp, the curve, etc.

2.The maximum speed of a metro train can reach 80 km/h, but for safety reasons, the maximum speed stipulated is only 74 km/h.

3.If you have to ask for a constant speed, there will be, but rarely, because the road conditions in the section are different, and the driver will adjust the traction or braking force of the train at any time according to the situation, so it is difficult to ensure a constant speed.

5.It takes about half a minute from starting to constant speed, and about half a minute for braking.

6.If there are 6 cars, the total is about 118 meters.

7.There are two kinds of subway power supply, one is catenary and the other is three-track. The catenary is similar to an electrified train with a power supply line overhead.

Three-track power supply is an additional track next to the two tracks, providing several hundred volts of high-voltage electricity. In the subway powered by three rails, it is dangerous to fall off the platform.

Legal analysis: This specification shall apply to the safety assessment before the initial operation of new subway and light rail projects, and the relevant provisions of the "Technical Specifications for Safety Assessment before Yinying in the Initial Operation Section of Urban Rail Transit Part 1: Subway and Light Rail" shall apply to reconstruction and expansion projects and rejection projects.

The system joint debugging should be completed before the trial operation.

Problem description: I see that many cities have installed barrier doors on subway platforms, but there are also some that are not installed (such as Guangzhou Metro), what are the benefits of installing barrier doors? What are the drawbacks?

Analysis: The advantages and disadvantages of the upstairs have been explained, the main advantage is that it can improve safety, prevent pedestrians from accidentally falling into the track and deliberately jumping off the track to commit suicide, ensure the safety of passengers and trains, and also prevent the loss of air conditioning to achieve the purpose of energy saving.

But I want to correct a point is that the landlord said that the Guangzhou subway did not install the screen door, in fact, Guangzhou is the first city in the country to install the screen door in the subway, Guangzhou Metro Line 2 is the first subway line in China to install the screen door, and then the opening of Metro Line 3 and Line 4 The first section and the line that will be opened later will be equipped with screen doors. Metro Line 1, which did not have a screen door, is also installing screen doors one after another, and the screen door at Huangsha Station can already be put into use.

With the acceleration of urbanization, iron has become an integral part of most people's lives. In the process of riding the subway, we can often find some thoughtful designs that help us travel more conveniently. At the same time, there are also some lack of convenient facilities, which makes us feel a little inconvenient.

Below I will share some of what I have seen and heard, and at the same time, ** some subway facilities can also be convenient.

First of all, let's take a look at some thoughtful design. The common ones are:

The seat and armrests are of moderate height and position, making it easy for people of different heights to use.

Electronic screens and radio messages remind people of train arrival information, transfer routes, etc., making it easier for people to plan their travel routes.

The carriages are equipped with air conditioning and ventilation systems, allowing people to comfortably ride the subway in both hot summers and cold winters.

Some subway stations have set up services such as vending machines and power bank rental points to make it easier for people to meet their daily needs.

In addition, the following convenient facilities can be added to the land:

Charging facilities: With the popularity of electronic devices such as mobile phones and tablets, there are more and more cases where passengers need to charge on the subway. Therefore, the subway can add charging stations to allow people to conveniently charge anytime, anywhere.

Wi-Fi coverage: Nowadays, people can't do without the Internet, and they need to keep the network open anytime, anywhere. Therefore, free Wi-Fi coverage should be provided in subway cars to provide people with a better network experience.

On-site navigation: Some of the larger metro stations, especially the transfer nodes, can easily get disoriented. Therefore, the subway can set up stereoscopic navigation maps, voice navigation, etc., to help passengers find the destination they need to go to faster.

Seat display system: Sometimes the seats in the carriage are already full, but there are still people coming in and crowding, which is easy to cause friction and dissatisfaction. As a result, subways can add seat display systems that allow passengers to see which seats are empty and avoid unnecessary hassles.

To sum up, as an important part of urban public transportation, the subway's thoughtful design and convenient facilities can make it more convenient and faster for people to travel. In the future, with the continuous development of technology and the acceleration of urbanization, we believe that there will be more convenient facilities and innovative designs for the subway, making our travel more comfortable and convenient.
