23 km

42 km

  • Population: 4.2 m
  • Land Area: 685 km2
  • 707,000 vehicles
  • 3,100 km of roads
  • 140 km rail network

Development Along MRT Corridors

  • Town planners decentralised the population into New Towns away from city centre, but connecting them by an efficient transport system
  • Concentrate the highest density developments around major transport nodes (MRT stations)
  • Economic benefits
    • stimulates investment
    • creates employment
    • enhances land values
the land transport authority
The Land Transport Authority (LTA) is the provider and owner of all road and rail infrastructure.

Our Mission: “To provide an efficient and cost effective land transport system for different needs.”

The Land Transport Authority
what is mass rapid transit
A passenger carrying railway with capacity in excess of 1500 persons per train.

Underground and Aboveground.

Frequent train services.

Short station stopovers.

The most efficient means of moving people in an urban environment.

the singapore mrt
The current MRT Network is operated by Singapore Mass Rapid Transit Ltd (SMRT) and Singapore Bus Service Transit Ltd (SBST).The Singapore MRT
the modern mrt
Highly Automated.

Increasingly Reliant on Fail-Safe Computer Based Systems.

Decreased Staffing Levels demands more effective means of communication.

Highly Reliable and Flexible Radio Communication is required for effective command and control purposes.

The Modern MRT
fully automated mrt
Fully automatic operation requires that all functions of the driver be automated.

Operation Control Centre must become the driver’s eye.

Efficient data transmission plays a key role in rapid indication and diagnosis of train-borne system faults.

Consistently clear communication with passengers is essential at all times.

Fully Automated MRT

Essential Features
conclusion
LTA has chosen TETRA for the following main reasons:

Feature Rich Radio System.

Provides Secure and Highly Reliable Concurrent Voice and Data Communications.

Highly Flexible and Expandable Catering for Future Needs and Network Expansions.

Modular and Upgradable Software based System Protects the Investment.

Conclusion
conclusion33
It is for these reasons that Singapore has chosen TETRA as the preferred technology to support the operation of the Singapore MRT operations.

TETRA is likely to be the choice for future MRT lines as the transit infrastructure in Singapore continues to grow rapidly.
