  1. Assessment approaches for certification INRETS EXPERIENCES

  2. INRETS ’ missions INRETS is a public research institute - under the joint supervision of Research and Transport Ministries to organize, execute and assess research transport systems,  to carry out technological assessment and decision support,  to promote technical developments, transfer of research results and to  improve scientific information dissemination.

  3. 1.We are- Research Unit Safety Research & Assessment Dependability Aspects in Railwaysectors-ATP systems • SoftwareHardware & System safety analysis • European projects: ERTMS, UGTMS, SAMRAIL and SAMNET • EURNEX, European Railway Research Network of Excellence (70 universities and reseach institutes)

  4. Estas main filed- Assesment • Systems assessed are : subways & trains like VALs, Maggaly, Meteor, TGV-North, TGV-South • Estas is a Certifer member, French Notified Body • Complexity depends on the degree of automatisation : Simplest = monitors the driver’s actions Most complex = fully automatic driving

  5. Projects in assessment field VAL of Lille 1, 2, VAL 208, Orly, Chicago, Toulouse, Rennes,Torino Roissy airport SK System and now VAL SYSTEM MAGGALY, line D of Lyon Renovation of lines A et B of Lyon METEOR Line 14 of Paris Transmanche Link ATP Line 2 of Cairo metro subway ATP TGV North ATP TGV Méditerranée Interlocking-PAI Signalling system SNCF Interlocking-PIPC Signalling system SNCF ERTMS French Base ATP TGV East

  6. Future:Risk analysis & safety assessment • Develop database (based on AEIF architecture) of railway functions to act as a harmonised basis for accident scenarios & risk apportionment • Common taxonomy (more than a glossary), model base (bowtie) and tools (software, etc.) for risk analysis • Harmonisation of a generic set of scenarios for risks to be controlled in all system phases, with emphasis on human factors • How to apply the generic set of scenarios to specific rail processes to define the necessary risk control measures + performance indicators/targets relevant to them – emphasis on human factors & links to rule management • How to translate the common safety indicators and targets into specific indicators for a given process in a given country

  7. Future: Risk analysis & safety assessment 2 • Develop better methods of analysing risk in maintenance activities & other transitions between system states • Develop harmonised approaches for assessing tolerable (societal/group) risk and comparing rail risk with other comparable risks (system boundary, units, exposure), to temper excessive demands for improved passenger safety • Assess the usefulness of minor injury statistics as performance indicator • Develop simulation models for safety validation (dynamic aspects), methodologies for the development of Cross Acceptance, interoperability and interchangeability criteria
