Center node: "experimental design for human in the loop driving simulations"
  Abstract: This report describes a new experimental setup for human-in-the-loop simulations. A force feedback simulator with four axis motion has been setup for real-time driving experiments. The simulator will move to simulate the forces a driver feels while driving, which allows for a realistic experience for the driver. This setup allows for flexibility and control for the researcher in a realistic simulation environment. Experiments concerning driver distraction can also be carried out safely in this test bed, in addition to multi-agent experiments. All necessary code to run the simulator, the additional sensors, and the basic processing is available for use.

Connected through hyperedge HE-1 (induced by source paper "people as sensors imputing maps from human actions"):
  with members:
    - "agreeing to cross how drivers and pedestrians communicate"
    - "evaluation of automated vehicles encountering pedestrians at unsignalized crossings"
    - "joint attention in autonomous driving jaad"
    - "identifying modes of intent from driver behaviors in dynamic environments"
