What are the different classifications of urban rail transit systems?

Urban rail transit vehicles are mainly divided into: urban railways, suburban railways, underground railways, light rail trams, monorail transit, maglev lines, new transportation systems, etc. Urban rail transit vehicles facilitate the daily travel of all of us and become an indispensable tool in our lives.

Urban rail transit under construction in the city needs a large number of rail transit professionals, the employment situation is very good in the next 5 to 10 years, and they live in big cities or provincial capitals. In China's cities that already operate rail transit, more and more residents choose to travel by urban rail transit. With the continuous improvement of urbanization rate, China's urban rail transit will enter a period of rapid and healthy development in the future, and at the same time, it will also bring a lot of development and employment space for urban rail transit employment.

Because smooth, convenient and reliable transportation is not only the basis for travelers to choose the mode of travel, but also the goal pursued by urban traffic managers, urban rail transit has become an important part of urban public transportation by virtue of its fast and convenient, high safety, large capacity and high transportation efficiency. The major of urban rail transit transportation and management is divided into subway direction and high-speed rail direction.

The direction of high-speed rail mainly focuses on cultivating service-oriented talents with good image, elegant temperament, high quality and strong communication skills, and the employment direction is mainly for high-speed rail crews, high-speed rail bars, security checks, security, ground handling, ticketing and other work inside and outside the province.

The subway direction mainly focuses on cultivating applied and compound talents with professional knowledge of urban rail transit operation and management, high comprehensive quality and strong urban rail professional skills, and can be engaged in urban rail transit operation and management production, command and management, operation and service. These jobs have a good employment environment, many promotion channels, high salaries, and guaranteed benefits. Urban rail transit is a good choice.

There are many types of urban rail transit, the technical indicators are quite different, and the evaluation standards of countries around the world are different, and there is no strict classification. Urban rail transit is developing rapidly in the world, due to the different regions, countries, cities, and different service objects, so that urban rail transit has developed into a variety of types.

1.Classified by way.

According to the guiding mode, urban rail transit can be divided into wheel-rail oriented urban rail transit system and guide rail guide.

to the urban rail transit system.

2.Classified according to the way the line is erected.

According to the way of line erection, urban rail transit can be divided into underground (underwater) urban rail transit system, new type of urban rail transit system of high subway and ground urban rail transit system.

3.Classified by the degree of line isolation.

According to the degree of line isolation, urban rail transit can be divided into fully isolated urban rail transit system and semi-isolated city.

Municipal rail transit system and non-isolated urban rail transit system.

4.Classification by track material.

According to the track material, urban rail transit can be divided into steel wheel rail urban rail transit system and rubber wheel concrete rail beam urban rail transit system.

5.Classified by towing method.

According to the traction mode, urban rail transit can be divided into rotary DC motor traction urban rail transit system, AC motor traction urban rail transit system and linear motor traction urban rail transit system.

6.Categorized by how operations are organized.

Urban rail transit can be divided into traditional urban rail transit, regional rapid rail transit and urban (suburban) railway according to the operation organization.

1.Classification according to operation Urban rail transit can be divided into the following two categories according to the operation scope in different areas of the city: 1) Urban rail transit:

The urban rail transit system, such as subway and light rail, generally belongs to this category. 2) Urban rail transit: the service scope covers the rail transit system within the urban area.

Such systems have different names in different countries, such as the RER line in Paris, France.

Urban rail transit has subways, public transportation, and various types.

Urban rail transit can be divided into ten categories: subway system, urban express rail system, light rail system, medium and low-speed maglev transportation system, cross-travel seat monorail system, suspended monorail system, self-guided rail system, tram system, guide rail rubber wheel system and electronic guide rubber wheel system. ”

There are many kinds of urban rail exchanges, and the technical indicators are quite different, mainly divided into seven categories: tram, subway, light rail, suburban railway, monorail system, maglev system, and new transportation system.

The seven types of urban rail transit are trams, underground railways, light rail transit, suburban railways, monorails, new transportation systems, and maglev trains. 1. Tram: It is a light and intelligent rail transit vehicle that is driven by electric strip force and runs on the track.

2. Underground railway: refers to the urban railway system that mainly runs underground.

Metro, light rail, monorail, tram, suburban railway, maglev, new transportation system.

What are the types of urban rail transit? The difference between them is: different natures and different characteristics.

Urban rail transit mainly includes underground railways, elevated railways, and surface railways.

Underground railway: does not occupy an area, does not pollute, has a large capacity, but is expensive.

Ground railway: no pollution, but it occupies a lot of land, is noisy, and has a great impact on other infrastructure.

Elevated track: no land, no pollution, construction cost is only 30 of the subway.

Urban rail transit is divided into "light rail" and "heavy rail" in terms of nature.

"Light rail" is an electrified railway system with a smaller capacity compared to "heavy rail". It can both share the road with other means of transport and drive on a dedicated road; It can be used to pick up and drop off passengers on a high platform, or in the form of a low platform, or even no platform. Vehicles can consist of single or multi-sections, and usually what we call modern trams fall into this category.

"Heavy rail" is also an electrified railway system with a larger capacity than "light rail". It must have a separate road; The vehicle consists of multiple carriages, and the speed and acceleration are fast; There are complex signaling systems; And there needs to be a higher platform to pick up and drop off passengers. The road to travel can be on the ground, underground, and on elevated lines.

Foreign "heavy rail" transportation systems include suburban trains, subway trains, etc.

Advantages and disadvantages of the subway:

1. The maximum one-way peak hour passenger flow that the subway can adapt to is 3-60,000 passengers.

2. The radius of the plane curve of the subway is not less than 300 meters, and the light rail is generally between 100 meters and 200 meters, and the number of trains in the subway is more than that of the light rail, and the number of vehicles is also more, so the conventional capacity of the subway is greater than that of the light rail.

3. The subway has the characteristics of large capacity, fast speed, safety, punctuality, environmental protection, energy saving and land use.

Urban rail transit is a complex system integrating multiple disciplines and types of work, which is usually composed of rail routes, stations, vehicles, maintenance and overhaul bases, power supply and transformation, communication signals, command and control centers, etc. The transportation organization, function realization and safety guarantee of urban rail transit should follow the objective law of rail transit. In the transportation group, Youmin should implement centralized scheduling, unified command, and organize traffic according to the operation chart.

In terms of functional realization, all relevant specialties such as lines, stations, tunnels, vehicles, power supply, communications, signals, mechanical and electrical equipment and fire protection systems should be in good condition and normal operation. In terms of safety assurance, it mainly relies on the normal operation of the driving organization and the setting to ensure the necessary driving interval and the correct driving route.
