The full form of MRTS is Mass Rapid Transit System.

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 system 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.

All public transport or mass transit system runs on infrastructure, either on roads, rail, airways or seaways.

Types of Mass Transit Systems include:

1. MRT (Mass Rapid Transit)
2. LRT (Light Rail Transit)
3. BRT (Bus Rapid Transit)
4. Metros
5. Commuter Rails

Between heavy rails and light rails, heavy rails are one of the better forms of mass transit as they are fast and will not interfere with the other traffic as they require separate underground infrastructure. But the initial cost of heavy rail is very high. It works best at places where a larger number of people will ride them such as in the center of big and densely populated cities.

The Singapore Mass Rapid Transit, or the MRT, as it is popularly known as was a small metro network to begin with. Back in the year 1987, it first began operations, thereby becoming the second oldest metro network, when compared with its neighbouring countries. The city places great emphasis on developing a sound public transportation network, with the MRT, greatly contributing to this. It currently runs on 5 lines, with 1 additional line that’s in its construction stage. If, things go according to plan, in addition to these 6 lines, 2 more lines will also be constructed. These 5 lines, run across a length of 170.7 km, while serving 102 stations along the way. SMRT Trains and SBS Transit are the two companies responsible for the operations of this massive network. Their dual participation in its operation makes it easy to integrate the metro with the other means of public transportation that are available. As a result of their continuous efforts, the MRT has a daily ridership north of 2 million passengers, as of 2015.
