    Conclusions / Recommendations

     Cooperative Positioning is needed to
     improve the positioning accuracy in the
     vehicular environment
     Communication constraints affect the level
     of accuracy that we can get from
     cooperative positioning

    Conclusions / Recommendations

     Efficient broadcast transmissions are a
     key factor in VANETs
     Tradeoff between reliability, latency and
     efficiency
     In safety related applications, latency is a
     critical issue
     A correct but too delayed information has
     no utility
     IF, with few adjustments, could be a
     solution

   Highlights from Presentation "Security Risk
Analysis Approach for on-board Vehicle Networks"

          Future vehicles will become mobile nodes
          in a dynamic transport network
                vehicle systems will be under threat from
                malicious individuals and groups seeking to
                gain personal or organizational advantage
                ensuring security will be critical for the
                successful deployment of V2X technology
          EU project EVITA aims to prototype a
          toolkit of techniques and components to
          ensure the security of in-vehicle systems
                hardware, software, analysis methods

    Conclusions / Recommendations

     A security risk analysis approach has been
     developed from automotive safety and IT
     security practices
                 attack trees to identify asset attacks from use cases,
                 attacker type and motivations
                 4-component security risk vector, potentially
                 including security-related safety issues
                 attack potential and controllability to assess
                 probability of successful attack
     Level and frequency of risks associated
     with asset attacks indicate priorities for
     counter-measures
                                                                 International

  Highlights from Presentation "The Benefits of
Enabling a Fully Autonomous Vehicle with Wireless
                 Communications"

      Automated, Autonomous,Communication-
      Enabled, and Cooperative – what do they
      mean
      Case study presented:
            Cooperative Sensor Sharing
            Cooperative Cruise Control
            Cooperative Convoy System
      Mobility, Safety, Environmental impacts
      are reviewed

    Conclusions / Recommendations

     The convergence of more aggressive
     active safety systems with more robust
     communication strategies will ENABLE the
     emergence of truly cooperative systems.
     The more “autonomous” vehicles become,
     the more they will need to interact
     cooperatively with their surroundings (V2I
     and V2V).
