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

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 current MRT Network is operated by Singapore Mass Rapid Transit Ltd (SMRT) and Singapore Bus Service Transit Ltd (SBST).
The Singapore MRT
![Page 11: Land Transport Authority TETRA IN A MASS RAPID TRANSIT ENVIRONMENT (Singapore) Presented by: Lee Thong Perng](https://reader033.vdocument.in/reader033/viewer/2022061616/56649e595503460f94b53884/html5/thumbnails/11.jpg)
Land Transport Authority
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.
![Page 12: Land Transport Authority TETRA IN A MASS RAPID TRANSIT ENVIRONMENT (Singapore) Presented by: Lee Thong Perng](https://reader033.vdocument.in/reader033/viewer/2022061616/56649e595503460f94b53884/html5/thumbnails/12.jpg)
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.
