Intersection Safety Systems (ISS) Development

Building on the success of the Intersection Safety Challenge, the Intersection Safety Systems (ISS) development initiative aims to support development of innovative ISS that can operate effectively under real-world conditions. The goal is to accelerate the development of full end-to-end prototype ISS and its components, including sensor fusion, AI-based decision-making, and conflict mitigation.

Key Research Questions

  • Conflicts. Can an ISS reliably predict conflicts among vehicles and vulnerable road users?
    • How far in advance can conflicts be predicted?
    • Under what conditions can reliable conflict predictions be made?
  • Unsafe Conditions. Can an ISS reliably identify conflicts and characterize unsafe conditions?
    • What types of unsafe conditions can be reliably identified or anticipated?
    • How quickly can unsafe conditions be reliably identified or anticipated?
  • Mitigating Strategies. Can an ISS take meaningful mitigating actions, either in the form of warnings or changes to intersection control, to mitigate conflicts and/or unsafe conditions?
    • Can changes to intersection control be implemented in real-time to mitigate unsafe conditions (e.g., eliminating permissive vehicle turning movements traversing busy crosswalks)? What changes to control are most effective?
    • Can warnings be issued in real-time to mitigate conflicts? What types of warnings are most effective (e.g., visual, auditory, haptic)?
    • Can modifications to intersection control be utilized to mitigate individual conflicts (e.g., delay the illumination of a WALK signal until all approaching vehicles have safely cleared the crosswalk)?
    • What are potential safety and congestion-reduction impacts resulting from these mitigating strategies?
