The essential data are mostly collected from web sites related with public transportation in Istanbul, especially those, who are in charge of running this tough business, and several conditions, rules and actions are created based on these data.

**Introduction**

 * [|Public transportation]** (also known as **mass transit**, **public transit**, and **public transport**) is defined as a passenger transportation system, which consists totally public services available for those people, who don’t make use of personal transportation vehicles or services such as personal cars and cars for hire.

A public transport system can be consisting of various vehicles such as busses, midi-busses and mini-busses, shared taxies, trains and commuter trains, trams, subways, trolleys, van pool services, paratransit, metrobusses, funicular systems, and also some vessels such as ferries, hydrofoils (sea busses), shared motor vessels, water taxies etc.

**Brief Information about Public Transportation System of Istanbul**
The mostly used mass transit vehicles in Istanbul are busses and metro-busses, midi-busses and mini-busses, shared taxies, subways, trams, commuter trains, nostalgic tram and tunnel-tram on the ground, and ferries, hydrofoils (sea busses), shared motor vessels on the sea. Even though the water taxies are available in Istanbul, they’re not that popular and mostly used. Their relative expensiveness might be stated as the most possible reason of their unpopularity in public transit.
