Types of Public Transport

Bus: Buses are one of the most common forms of public transport. They follow fixed routes and schedules, stopping at designated bus stops. They are relatively flexible and can cover a wide area, reaching various neighborhoods and suburbs.

Subway/Metro: Subways or metros are rapid transit systems that usually run underground in urban areas. They are known for their high speed and capacity, capable of transporting a large number of passengers quickly. They are ideal for reducing traffic congestion in dense cities.

Train: Trains include commuter trains, regional trains, and long-distance trains. Commuter trains are used for daily travel between suburbs and city centers. Regional trains connect different cities and towns within a region, while long-distance trains are used for traveling across the country.

Tram/Streetcar: Trams or streetcars run on tracks along the streets. They are often used in city centers and have a slower speed compared to subways but offer a more scenic and accessible mode of transport, stopping at frequent intervals.

Light Rail: Light rail systems are similar to trams but are usually more modern and have a higher capacity. They can operate on a mix of street-level and dedicated tracks and are often used to connect different parts of a city or serve growing suburbs.

Ferry: Ferries are used for waterborne transport, carrying passengers across rivers, lakes, or bays. They are common in coastal cities or areas with significant waterways and can provide a unique travel experience.
