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.

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 drivers actions
• Most complex fully automatic driving

FutureRisk 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

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
