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.”
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 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.
Land Transport Authority
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.

Why TETRA ?
Land Transport Authority
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.
Land Transport Authority
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).

Land Transport Authority
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.
Land Transport Authority
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.
