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.”


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 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.


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.


Radio Requirements Digital Technology

Benefits from Digital Signal Processing.

Robust and Reliable Communication Link.

Combined Voice and Data ServicesSimultaneous Voice and Data

Transmission.


Radio Requirements

Automated Resource ManagementBandwidth Occupancy only when

Needed.Increased Capacity through Shared

Resources and Trunking Schemes.


Radio Requirements

Ease of ExpansionModular System.Support Future Network and Channel

Growth. Advanced Networking Capabilities

Inter-working with Other Networks.


Radio Technology

Why TETRA ?


Why TETRA ? Frequency Economy

Interleaving 4 Channels in a single 25kHz Carrier via TDMA scheme.

Security for Critical DataData Integrity through Forward Error Correction.

Consistent Voice QualityNo Analogue Circuit Degradation Caused by

Noise and Distortion.Less User Frustration and Stress.


Why TETRA ?

Flexible CommunicationsSupports both Voice and Data

applications.Efficient Command and Control (fast call

set-up, subscriber identification, priority management, individual, group and broadcast calls).


Why TETRA ?

Automated Voice/Data Traffic Routing and Network Flexibility

Software Based Configurable Architecture.

Trunked System Controller.Roaming between Systems.

Essential Features

Easily Upgradable, Scaleable, ExpandableProgrammable Options provide Flexibility.Fully Synthesised, not Hard-wired.Modular Hardware Design.

Ease in Migration of System ControlControl Functions can be allocated at any

Dispatcher Location through Soft Configuration.


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

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.
