  1. TETRA IN A MASS RAPID TRANSIT ENVIRONMENT(Singapore) Presented by: Lee Thong Perng

  2. Singapore 23 km 42 km • Population: 4.2 m • Land Area: 685 km2 • 707,000 vehicles • 3,100 km of roads • 140 km rail network

  3. 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

  4. 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

  5. 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. What is Mass Rapid Transit ?

  6. N Present Development North-South Line North Est Line East-West Line MRT No. of lines 3 Route length (km) 109 No. of stations 67 No. of depot 4

  7. Length: Stations: 172 km 139 N Development Y2010 Circle Line Completion: (In 3 Phases) 2007/2008/2010 Circle Line

  8. JRL ETL BKL N Rail Transit Development Programme (Under Study) Rail Transit SystemBy Y2015

  9. The current MRT Network is operated by Singapore Mass Rapid Transit Ltd (SMRT) and Singapore Bus Service Transit Ltd (SBST). The Singapore MRT

  10. 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

  11. 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

  12. Digital Technology Benefits from Digital Signal Processing. Robust and Reliable Communication Link. Combined Voice and Data Services Simultaneous Voice and Data Transmission. Radio Requirements

  13. Automated Resource Management Bandwidth Occupancy only when Needed. Increased Capacity through Shared Resources and Trunking Schemes. Radio Requirements

  14. Ease of Expansion Modular System. Support Future Network and Channel Growth. Advanced Networking Capabilities Inter-working with Other Networks. Radio Requirements

  15. Why TETRA ? Radio Technology

  16. Frequency Economy Interleaving 4 Channels in a single 25kHz Carrier via TDMA scheme. Security for Critical Data Data Integrity through Forward Error Correction. Consistent Voice Quality No Analogue Circuit Degradation Caused by Noise and Distortion. Less User Frustration and Stress. Why TETRA ?

  17. Flexible Communications Supports both Voice and Data applications. Efficient Command and Control (fast call set-up, subscriber identification, priority management, individual, group and broadcast calls). Why TETRA ?

  18. Automated Voice/Data Traffic Routing and Network Flexibility Software Based Configurable Architecture. Trunked System Controller. Roaming between Systems. Why TETRA ?

  19. Please Stay Calm Help is on the way ….. Flexible Communication Trainborne Alarms Emergency Broadcast to passengers Please Stay Calm ……. Trainborne Display Live PA Broadcast Combined Voice & Data

  20. Contributes to High Service Availability Remote Monitoring and Diagnostics. Efficient Incident Management. Why TETRA ?

  21. Dynamically Grouped Calls Incident Management Grouped Data or Voice Communications for Incident Management Base Station Incident Area

  22. Dynamically Grouped Calls Incident Management Grouped Data or Voice Communications for Incident Management Base Station Incident Area

  23. Public Address Announcement from Control Rooms to Trains. Passenger Communication with Control Rooms During Emergencies. Automatic Telephone Patch to PABX Subscribers. Patch to Station PA Systems. Communication amongst operation and maintenance staff. Voice Traffic

  24. Higher Priority Emergency CommunicationPEC: Passenger Emergency Communication Lower Priority On Hold Control Centre PEC Low priority calls Passenger

  25. Train-borne CCTV Selection from Control Rooms. Remote Triggering of Train-borne Voice and Text Messages. Updating of pre-stored Train-borne Text and Voice Message Libraries. Data Services

  26. Trainborne Passenger Information Display Data from Control Rooms. Trainborne PA Control from Control Rooms. Train Fault and Diagnostic Data from the Trains to Control Room and Maintenance Centres. Data Services

  27. Remote Data Upload/Download Voice Comm. Data Files Download Crew Member Depot Control Centre Train Fleet Alarm Data

  28. Open Standard Interfaces Voice Communication across Multiple Virtual Private Networks. Interconnections with other TETRA compliant Networks. Multi-Vendor Support. Operational Flexibility Software Control of All Aspects. Essential Features

  29. Typical Radio System Connectivity Train Train Train Depot PSTN Station Control Centre Depot Control Station Portable ISI Other Networks Portable Portable Portable Station Boundary Station Boundary Train Direct access With Authorisation Trunk Line

  30. Easily Upgradable, Scaleable, Expandable Programmable Options provide Flexibility. Fully Synthesised, not Hard-wired. Modular Hardware Design. Ease in Migration of System Control Control Functions can be allocated at any Dispatcher Location through Soft Configuration. Essential Features

  31. 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

  32. 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. Conclusion
