As we all know, public transportation is a shared transportation service that can be availed by the public for a fare or sometimes it’s free. Public transportation is also known as public transit or mass transit and is quite different from car pooling or hailing a cab because in public transport, the service is shared by strangers.

There are different modes of public transport; these can be enumerated and explained as follows:

1. Airline – This type of public transportation is used when it is impossible to get to the destination by other modes of transportation because of there is no proper ground infrastructure. Hence this mode is preferable for long distance journeys. The speed at which airlines travel is very high and hence one can get to the destination very fast but has to incur a lot of waiting time prior to the travel or after the travel by aircrafts. Bush airlines are another example, it works just like bus stops; i.e. when the aircraft is full of passengers, it takes off.

1. Buses or coaches – These are probably the most common mode of public transportation. They operate on conventional roads and has the ability to carry a large number of passengers. Other forms of buses are electric buses and trolleybuses, these do not work like conventional buses because they require overhead wires for its operation. Nowadays, electrical buses also ply the road; these are buses that work on batteries which can be recharged via underground wires.

1. Trains – After the bus, this is the second most common mode of public transportation. Depending on the built, trains can be fast or slow. Common forms of urban rail transit are light rail, rapid transit, trams, funiculars, commuter rail, people movers, etc. Some of the high speed passenger trains can run at a speed of 120 miles per hour! Countries like Europe and Japan have well developed high speed rail transport system and are a great alternative for air travel because it is both fast and comparatively cheaper.

A new concept of train transit is the personal rapid transit which is like the cab service but it is automated and it does not run on conventional roads, instead it operates on guideways or rails. This type of transport is quite uncommon. Unlike the cab or taxis, personal rapid transit is not labour-oriented. It drops people directly to the location of their choice.

1. Ferry – A ferry can be defined as a boat or ship that carries people or even vehicles sometimes, across a water body. Water bus is a common form of ferry; it works just like bus, in the sense that it carries passenger only and has many stops. Ferry services is not only limited to a small water body, the ships that carries passengers across large water bodies like the Mediterranean sea are also termed as ferry services.
