UK Railways - A proposal to provide a Ubiquitous Train Location Service (TLS)

  1. 1. UK Railways A proposal to provide a Ubiquitous Train Location Service (TLS) Airports Air Traffic Management Space Andrew Sage Director, Helios 30th November 2011 Telecoms Maritime Rail www.askhelios.com
  2. 2. This presentation will demonstrate the commercial and safety value of train location information • • • • • The value of train location information Establishing a business case for investment The lack of solutions ‘off the shelf’ How the UK rail industry is tackling the problem… …and the challenge to the navigation industry
  3. 3. This presentation will demonstrate the commercial and safety value of train location information • • • • • The value of train location information Establishing a business case for investment The lack of solutions ‘off the shelf’ How the UK rail industry is tackling the problem… …and the challenge to the navigation industry
  4. 4. Network capacity has struggled to maintain progress with passenger demand
  5. 5. Growth in demand for rail services looks set to continue despite current economic conditions • Rapid growth in demand from 1996 to 2009 • Road passenger miles up 9% • Rail passenger miles up 56% • Rail freight has grown by 47% over the last fifteen years, and has started to grow again since 2010 • The UK Office of the Rail Regulator predicts a doubling of passenger demand by 2030
  6. 6. The ‘4 C’s of the UK railways and their dependency upon train location information • CAPACITY • Dynamic traffic management • Incident management/recovery • CARBON • Energy-optimised driving • Energy monitoring • COST • Low cost Train Control • Asset management/maintenance • CUSTOMER • Passenger information • CCTV/public safety
  7. 7. Train location underpins a very wide range of safety and operationally critical applications Examples of application classification Non-safety Non-safety Safety-related Safety-related Safety-critical Safety-critical • PIS • PIS • Asset management • Asset management • Signalling • Signalling • Position/time • Position/time stamping stamping • SDO • SDO • CCTV • CCTV • PLD • PLD • OTMR • OTMR • Engine monitoring • Engine monitoring • Fleet management • Fleet management • Track mapping • Track mapping • Traffic management • Traffic management • Train position • Train position referencing referencing

  9. 9. So what’s the problem?.... • Distribution of costs and benefits amongst a fragmented group of organisations • Systems procured with short term view – driven by requirements of single applications • A lack of common standards to enable interoperability and sharing of information • Stringent rail requirements that mean ‘special’, and therefor expensive solutions • A lack of ‘buying power’ in the UK and the wider European rail industry • A lack of understanding in the performance shortfalls of GNSS only solutions
  10. 10. Fragmentation makes it difficult to achieve a positive business case without consensus Passengers/ “Societal Benefit” Businesses Government £+/- 200m 50bn km £5bn £ tax £6bn Delay Network Rail minutes Track access Investment Supply industry Operating companies Passenger/Freight Maintenance ROSCOs
  11. 11. The use of GNSS remains relatively limited to a small subset of applications • Penetration of GPS in railways is growing • ~75% of trains equipped with GPS – only for non-critical passenger/management information applications • No operational use of GPS for safety critical applications • Examples of use and trials within the UK • Passenger information • Freight and asset management • Selective door opening (SDO)
  12. 12. Many lessons have already been learnt from previous installations of GPS • Insufficient match between application requirements and equipment capability • Too cheap (eg consumer devices) • Too expensive (eg survey grade) • Lack of knowledge of GPS performance shortfalls • Multipath and shadowing near main stations/gantries • Lack of service continuity • Time to first fix (TTFF) • Insufficient antenna engineering and location • Duplicate system elements and therefore increased through-life costs
  13. 13. This presentation will demonstrate the commercial and safety value of train location information • • • • • The value of train location information Establishing a business case for investment The lack of solutions ‘off the shelf’ How the UK rail industry is tackling the problem… …and the challenge to the navigation industry
  14. 14. Traditional means of train location cannot be assumed on all parts of the network • Train location information for signalling purposes is achieved with physical train detection • delivers a high level of availability and integrity necessary for safety critical operations. • Long term vision of the railways includes the elimination or significant reduction of infrastructure based train detection • Need to reduce ongoing operational and maintenance costs • ERTMS Level 3 is the planned approach to doing this and would require the removal of lineside train detection • There is no single system capable of delivering location with the coverage, availability, integrity and accuracy to satisfy application demands
  15. 15. The GNSS device landscape in the land sector has been rapidly diverging into two broad families of receiver Consumable chipsets • • • • • • Users – mobile phones, PNDs Price <1$ price Lifetime <3 yrs Functionality – ‘hardwired’ in silicon Integrated into common processing unit Market is growing exponentially Professional receivers • Users – geodetic, high precision, professional • Price >$2k • Lifetime 5-15 yrs • Firmware (and some software) upgrades • Dedicated PVT processor and platform • Market is growing steadily
  16. 16. Rail has fallen into the ‘urban chasm’ that appears to have opened up in the GNSS market POSITION ACCURACY IN-CAR NAVIGATION PROFESSIONAL ROAD RAIL SAFETY-OF-LIFE REGULATED PEDESTRIAN NAVIGATION PROFESSIONAL (EG AGRI) COMMERCIAL DGNSS GEODETIC SURVEY GNSS SERVICE AVAILABILITY

This presentation will demonstrate the commercial and safety value of train location information • • • • • The value of train location information Establishing a business case for investment The lack of solutions ‘off the shelf’ How the UK rail industry is tackling the problem… …and the challenge to the navigation industry
  18. 18. RSSB’s existing guidance on GNSS is already being used widely – both in UK and around Europe • Appreciation of satellite navigation and its limitations • Summary of augmentations available (SBAS, INS, odometer, map matching…) • Quality of Service (QoS) parameters • Technical options and classes of receiver equipment • Interface standards • Equipment selection • Installation, approvals, integration and maintenance
  19. 19. Augmentations are necessary to deliver the improvements in availability and integrity Increasing performance GPS alone GPS alone OR One-step upgrade Two-step upgrade Increase availability of position report Increase accuracy, integrity and availability GPS + basic INS GPS + basic INS Increase accuracy and integrity of position report GPS + INS GPS + INS + SBAS + SBAS OR GPS + basic INS GPS + basic INS + terrestrial + terrestrial augmentation augmentation OR GPS + basic INS GPS + basic INS + RAIM + RAIM OR GPS + basic GPS + basic INS + INS + simple map simple map matching matching Standardized interfaces allow plug & play Standardized interfaces allow plug & play IIL LL LU US ST TR RA AT TIIV VE E
  20. 20. Market intervention is required to ensure a long term and cost effective solution Anticipated COTS solutions and trends in navigation technology are too late for application timescales
  21. 21. Proposed programme for a ubiquitous Train Location Service (TLS) • Funding is currently being sought for the first year’s (2012) programme of activities • The work should be undertaken in partnership • Other European rail organisations and standards bodies • Navigation industry • • • • • Develop a “Concept of Operations” for a TLS Analysis of application requirements Technology gap analysis Value For Money (VFM) and affordability analysis Supply Chain / Market Analysis

This presentation will demonstrate the commercial and safety value of train location information • • • • • The value of train location information Establishing a business case for investment The lack of solutions ‘off the shelf’ How the UK rail industry is tackling the problem… …and the challenge to the navigation industry
  23. 23. The ideal GNSS receiver for most rail applications would ensure long-term flexibility • • • • • • • • Ability to upgrade to multi-constellation, single frequency GNSS (L1 GPS, Galileo and GLONASS) Integrated with INS or on-board odometer to provide necessary service continuity Potential to support multi-GNSS RAIM in the future Assistance data via WiFi/GSM-R for cold starts (eg in depot) Equipment lifetime at least 10 years Open standards for antenna input and PVT output to support multiple applications Integrated with on-board map/ rail network model …and all at COTS prices
  24. 24. …and it must also work on both of these!
  25. 25. Summary of key messages to take away • Train location is about more than just signalling • Sharing dynamic location information between stakeholders is critical for an efficient network • GNSS on it’s own is not good enough and traditional rail infrastructure can no longer be relied upon • Solutions are not available ‘off the shelf’ and therefore a combination of different methods is needed • The rail sector represents a new and innovative opportunity for the navigation industry • The UK rail sector is seeking to tackle these issues in partnership with other European bodies 24
