For some of us living in big cities, imagining our lives without the Metro would be difficult. The method of transport allows us to travel major distances much faster while simultaneously helping us skip the road traffic and greater exposure to pollution. When compared to private automobiles, this mode of transportation is also quite affordable. Based on all these reasons, the popularity of the Metro rail has gone up significantly.

Rapid transit or mass rapid transit MRT , also known as heavy rail , metro , subway , tube , U-Bahn , metropolitana or underground , is a type of high-capacity public transport generally found in urban areas. Modern service on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks , although some systems use guided rubber tires, magnetic levitation maglev , or monorail.

The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by the same public transport authorities.

However, some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. The world's first rapid transit system was the partially underground Metropolitan Railway which opened as a conventional railway in , and now forms part of the London Underground. Metro is the most common term for underground rapid transit systems used by non-native English speakers. One of these terms may apply to an entire system, even if a large part of the network for example, in outer suburbs runs at ground level.

In Scotland , however, the Glasgow Subway underground rapid transit system is known as the Subway. In most of North America , underground mass transit systems are primarily known as subways. Chicago 's commuter rail system that serves the entire metropolitan area is called Metra short for "Metropolitan Rail" , while its rapid transit system that serves the city is called the "L". The opening of London's steam-hauled Metropolitan Railway in marked the beginning of rapid transit.

Initial experiences with steam engines, despite ventilation, were unpleasant. Experiments with pneumatic railways failed in their extended adoption by cities. Electric traction was more efficient, faster and cleaner than steam and the natural choice for trains running in tunnels and proved superior for elevated services. The Liverpool Overhead Railway was designed to use electric traction from the outset.

The technology quickly spread to other cities in Europe, the United States, Argentina, and Canada, with some railways being converted from steam and others being designed to be electric from the outset. Budapest , Chicago , Glasgow and New York all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services.

Hybrid solutions have also evolved, such as tram-train and premetro , which incorporate some of the features of rapid transit systems. The first rapid transit line in Australia was opened in Sydney in , which will feed into a larger network known as the Sydney Metro upon completion of a second line in Since the s many new systems were introduced in Europe , Asia and Latin America. Rapid transit is used in cities , agglomerations , and metropolitan areas to transport large numbers of people often short distances at high frequency.

The extent of the rapid transit system varies greatly between cities, with several transport strategies. Some systems may extend only to the limits of the inner city, or to its inner ring of suburbs with trains making frequent station stops.

The outer suburbs may then be reached by a separate commuter rail network where more widely spaced stations allow higher speeds. In some cases the differences between urban rapid transit and suburban systems are not clear. Rapid transit systems may be supplemented by other systems such as trolleybuses , regular buses , trams , or commuter rail.

This combination of transit modes serves to offset certain limitations of rapid transit such as limited stops and long walking distances between outside access points. Bus or tram feeder systems transport people to rapid transit stops. Each rapid transit system consists of one or more lines , or circuits. Each line is serviced by at least one specific route with trains stopping at all or some of the line's stations.

Most systems operate several routes, and distinguish them by colors, names, numbering, or a combination thereof. Some lines may share track with each other for a portion of their route or operate solely on their own right-of-way. Often a line running through the city center forks into two or more branches in the suburbs, allowing a higher service frequency in the center. Alternatively, there may be a single central terminal often shared with the central railway station , or multiple interchange stations between lines in the city center, for instance in the Prague Metro.

The Chicago 'L' has most of its lines converging on The Loop , the main business, financial, and cultural area. Some systems have a circular line around the city center connecting to radially arranged outward lines, such as the Moscow Metro 's Koltsevaya Line and Beijing Subway 's Line The capacity of a line is obtained by multiplying the car capacity, the train length, and the service frequency.

Heavy rapid transit trains might have six to twelve cars, while lighter systems may use four or fewer. Cars have a capacity of to passengers, varying with the seated to standing ratio —more standing gives higher capacity. The minimum time interval between trains is shorter for rapid transit than for mainline railways owing to the use of Communications based train control : the minimum headway can reach 90 seconds, but many systems typically use seconds to allow for recovery from delays.

Typical capacity lines allow 1, people per train, giving 36, people per hour. Rapid transit topologies are determined by a large number of factors, including geographical barriers, existing or expected travel patterns, construction costs, politics, and historical constraints.

A transit system is expected to serve an area of land with a set of lines , which consist of shapes summarized as "I", "U", "S", and "O" shapes or loops. Geographical barriers may cause chokepoints where transit lines must converge for example, to cross a body of water , which are potential congestion sites but also offer an opportunity for transfers between lines.

Ring lines provide good coverage, connect between the radial lines and serve tangential trips that would otherwise need to cross the typically congested core of the network. A rough grid pattern can offer a wide variety of routes while still maintaining reasonable speed and frequency of service. Line , e. Cross, e. X-shaped, e. Two crossing paths air bladder , e. Secant , e. Radial, e. Circle-radial, e. Complex grid, e. Extended loop, e. Sofia , Naples , Newcastle. Rapid transit operators have often built up strong brands , often focused on easy recognition—to allow quick identification even in the vast array of signage found in large cities—combined with the desire to communicate speed, safety, and authority.

A transit map is a topological map or schematic diagram used to show the routes and stations in a public transport system. The main components are color-coded lines to indicate each line or service, with named icons to indicate stations. Maps may show only rapid transit or also include other modes of public transport. Maps help users understand the interconnections between different parts of the system; for example, they show the interchange stations where passengers can transfer between lines.

Unlike conventional maps, transit maps are usually not geographically accurate, but emphasize the topological connections among the different stations. The graphic presentation may use straight lines and fixed angles, and often a fixed minimum distance between stations, to simplify the display of the transit network.

Often this has the effect of compressing the distance between stations in the outer area of the system, and expanding distances between those close to the center. Some systems assign unique alphanumeric codes to each of their stations to help commuters identify them, which briefly encodes information about the line it is on, and its position on the line. Seoul Metro is another example that utilizes a code for its stations.

But unlike that of Singapore's MRT, it's mostly numbers. Based on the line number, for example Sinyongsan station, coded as station As it is on Line 4, the first number of the station code is 4. The last 2 numbers will be the station number on that line.

Interchange stations can have multiple codes. It has a code of and respectively. The Line 2 is a circle line and the first stop is City Hall, therefore, City Hall has the station code of For lines without a number like Bundang line it will have an alphanumeric code. With widespread use of the Internet and cell phones globally, transit operators now use these technologies to present information to their users.

In addition to online maps and timetables, some transit operators now offer real-time information which allows passengers to know when the next vehicle will arrive, and expected travel times. The standardized GTFS data format for transit information allows many third-party software developers to produce web and smartphone app programs which give passengers customized updates regarding specific transit lines and stations of interest.

Compared to other modes of transport, rapid transit has a good safety record, with few accidents. Rail transport is subject to strict safety regulations , with requirements for procedure and maintenance to minimize risk.

Head-on collisions are rare due to use of double track, and low operating speeds reduce the occurrence and severity of rear-end collisions and derailments. Fire is more of a danger underground, such as the King's Cross fire in London in November , which killed 31 people. Systems are generally built to allow evacuation of trains at many places throughout the system. Platform screen doors are used on some systems to eliminate this danger.

Rapid transit facilities are public spaces and may suffer from security problems: petty crimes , such as pickpocketing and baggage theft, and more serious violent crimes , as well as sexual assaults on tightly packed trains and platforms. In some countries a specialized transit police may be established. These security measures are normally integrated with measures to protect revenue by checking that passengers are not travelling without paying.

Some rapid transport trains have extra features such as wall sockets and internet connectivity. The technology used for public, mass rapid transit has undergone significant changes in the years since the Metropolitan Railway opened publicly in London in High capacity Monorails with larger and longer trains can be classified as rapid transit systems.

Light metro is a subclass of rapid transit that has the speed and grade separation of a "full metro" but is designed for smaller passenger numbers. It often has smaller loading gauges, lighter train cars and smaller consists of typically two to four cars. Light metros are typically used as feeder lines into the main rapid transit system. Some systems have been built from scratch, others are reclaimed from former commuter rail or suburban tramway systems that have been upgraded, and often supplemented with an underground or elevated downtown section.

This method of construction is the cheapest as long as land values are low. It is often used for new systems in areas that are planned to fill up with buildings after the line is built. Most rapid transit trains are electric multiple units with lengths from three to over ten cars.

Power is commonly delivered by a third rail or by overhead wires.

Mass Transit System – Impacts, Advantages & Disadvantages

The greatest advantage of the railway transport is that it is the most dependable mode of transport as it is the least affected by weather conditions such as rains, fog etc. The rail transport is better organised than any other form of transport. It has fixed routes and schedules. Its service is more certain, uniform and regular as compared to other modes of transport. Its speed over long distances is more than any other mode of transport, except airways. Thus, it is the best choice for long distance traffic. Railway transport is economical, quicker and best suited for carrying heavy and bulky goods over long distances.

Urban freight movement by rail. Movimento de mercadorias por ferrovias em zonas urbanas e suburbanas. This paper explores the idea of using existing urban and suburban rail networks for distributing and delivering goods in cities. Six case studies are discussed, where four of them have already been implemented in European cities: Amsterdam, Dresden, Paris and Zurich. The Newcastle metro potential to transport freight is also analysed.

Metro systems around the world have many differences in their design and operation, one aspect of which is the level of automation. The most advanced technology available allows for unattended train operation with no staff on-board, which can bring a number of benefits. This paper uses the Tyne and Wear Metro as a case study to highlight the potential benefits and obstacles of implementing driverless trains on an existing metro system.

Metro bus advantages and disadvantages

The rapid expansion of new metro systems in the last two decades shows a globally growing interest in urban rail transit infrastructure. Every time a new metro line is opened, it has the potential to change the existing modal split, which is usually dominated by private car or motorcycle transport users. For each new or expanding metro system, a feasibility study is conducted, which focusses mainly on existing mobility issues, travel demand, new infrastructure proposed, and environmental and financial aspects of a new metro project. In these documents, specific methodologies are applied, using local parameters and suitable software, for demand forecasting purposes. However, not much attention is usually dedicated to potential users, their modal choice characteristics, willingness to shift to metro and conditions under which such a shift would be encouraging.

Mass transit system refers to public shared transportation, such as trains, buses, ferries etc that can commute a larger number of passengers from origin to destination on a no-reserved basis and in lesser time. It can also be termed as Public Transport. Rapid transit is an important form of mass transit such as subways and surface light rail systems, designed for commuting inter-city or intra-city. Mass transit may be based on fixed route system such as subway trains, metros or non-fixed route system such as buses. It is potentially more economical, eco-friendly and less time consuming. In addition it is the most competent way of reducing the ever growing traffic congestion of the developing city. Mass transit has the advantage of smaller rights of way and developing lesser amount of infrastructure required for highways and roads.

Road transport means transportation of goods and personnel from one place to the other on roads. Road is a route between two destinations, which has been either paved or worked on to enable transportation by way of motorised and non-motorised carriages. There are many advantages of road transport in comparison to other means of transport. The investment required in road transport is very less comp. Rail transport is also known as train transport. It is a means of transport, on vehicles which run on tracks rails or railroads.

У нее часто возникало чувство, что Стратмор не слишком высокого мнения о Дэвиде и считает, что она могла бы найти себе кого-то поинтереснее, чем простой преподаватель.

Сьюзан не могла скрыть изумления. NDAKOTA - анаграмма. Она представила себе эти буквы и начала менять их местами. Ndakota… Kadotan… Oktadan… Tandoka… Сьюзан почувствовала, как ноги у нее подкосились. Стратмор прав.
