  • The FESTA “V” showing where the focus of this presentation lays.
  • The focus for this presentation is on in-vehicle DAS DAS, but there are also other means of data collection
  • Several different DAS systems. This due to different systems tested and differences in experience and previous usage.
  • Many different challanges

    2. 2. www.eurofot-ip.eu Contents • Illustration of different approaches for Data Acquisition Systems and challenges • Illustration of data analysis tools and challenges. • Practical issues to be considered in large scale FOTs. September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    3. 3. www.eurofot-ip.eu Project objectives and plans September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    4. 4. www.eurofot-ip.eu Definition of Data Acquisition System • In-Vehicle DAS • External services – e.g. map/weather • Questionnaires (subjective data) • Background data (driver/vehicle) September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    5. 5. www.eurofot-ip.eu In-Vehicle DAS in euroFOT • Different DAS system used at different sites, but with common basic methodology • CAN (vehicle bus) only • CAN + video + (extra sensing) September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    6. 6. www.eurofot-ip.eu Challenges in in-vehicle DAS implementations in euroFOT • Difficult to find appropriate DAS systems for CAN+video • Multiple vehicle bus interfaces needed • Stability of the systems must be very high and require automotive spec. components (incl. EMC). • Making sure integrity and proprietary issues for data access are covered • Easy configuration and installation in vehicles September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    7. 7. www.eurofot-ip.eu Challenges for data analysis tools in euroFOT • Working with huge amounts of data Data processing time – database querying and calculations Quality assurance in analysis Database design to allow for multi user analysis and data upload How to get an overview September 2009 Jonas Bärgman – ITS 2009 - Stockholm
    8. 8. www.eurofot-ip.eu Practical issues in large-scale FOTs • Vehicles, installation and configuration • Study design that allows for system boundary conditions • Quality assurance of data – definitions and implementation • Wireless data transfer – roaming costs • Handling of vehicle bus information • Consistency and traceability of data and analysis • Data storage implementation – HW/SW • Access rights and multi user handling September 2009 Jonas Bärgman – ITS 2009 - Stockholm
