SAFER’s organisation –
22 partnersGovernment
Universities Industry
The SAFER NDS/FOT Collaboration• 13 partner including:
• 4 vehicle manufacturers (OEMs) + 1 supplier• Swedish Transport Administration• Universities and institutes from Sweden and Norway
• Working with sensitive data: • Personal integrity (video etc)• Proprietary issues (vehicle CAN –
ADAS systems)
• Joint analysis (project dependent):• Combine data from several OEMs• Combine competences from SAFER partners
• All under ”one roof”

Research Focus within NDS/FOT
• Crash Relevant Events (CRE) for accident research
• Evaluation of advanced active safety systems
• Driver inattention –
specifically visual behavior
• New statistical approaches to NDS/FOT data analysis
• Use NDS/FOT data for crash causation factor break down
SeMiFOT1 -
The Aim
•
Implement and develop the Naturalistic Field Operational Test method into a powerful tool for (a) accident research, (b) evaluation of safety, efficiency, and
usage & acceptance, and (c) countermeasure innovation and
development.

• Technical aspects • Review and comparison of data acquisition from US, EU and Japan• Data acquisition systems, database/storage, and analysis tools• Data sharing and collaboration procedures• 170,000 km over12,000 trips collected
• Analysis• Crash Relevant Events (trigger design, manual review proc. etc) • Linking databases with FOT-data (map / accident statistics etc)• Events prevented• Visual behavior• Benefits of Origin and Destination Information in VII Data Set •

Events Prevented Simulated vehicle trajectories with and without LDW
Relationship Between Driving Performance Metrics (Quantifying ”Oops”) and Visual behavior
•
Implementing driver performance metrics (e.g. ReversalRate, AbsMaxLatAccel, StdLatAccel, MinLongAccel)
•
Developing state-of-the-art adaptive quality and smoothing filters

Crash causation breakdown -
DREAMi•
How can method(s) developed for in-depth crash causation research be applied on NDS/FOT data?
•
What modifications are needed?•
What is different when applied to incidents vs. crashes? Comparability?
•
Collaboration with Japan Automobile Research Institute (JARI) –

Storage/database•
Analysis tools•
Pre/post processing and data quality•
Procedures: Data sharing, manual annotation, etc
SeMiFOT2 –
analysis onlyQuestions:
•
What explanatory factors are associated with crashes or crash surrogates and can be used to predict crash or crash surrogates?• How does driver distraction influence crash likelihood?• How do dynamic driver characteristics influence crash likelihood?
• Implementation• Develop quantitative definitions of CRE severity• Extraction of CREs
(triggers/reduction)• Exploration of statistical and analytical approaches for CRE analysis•
Analysis of the impact of visual behaviour on driving performance and CREs• Expansion of SeMiFOT
