  1. Applying Knowledge Representation to Runway Incursion csci477 – Senior Design Capstone Class FAA Airport Design Competition for Universities Spring, 2007

  2. The Problem of Runway Safety/Runway Incursion • Airports are complicated places with many safety requirements. • How do they manage safety? • How are they held accountable? • Can airports be designed to be safer? • In particular, there are many techniques to mitigate the incursion risks found at airports. • How are airports made aware of them? • Which are most effective? • Real-time incursion detection and recovery is a critical function of air-traffic control. • What techniques are available? • How can new techniques be introduced to airports?

  3. The Technology Challenge • Can the information required to answer the questions raised by the previous slide be captured and used by computers? • Yes, use an AI Knowledge Representation (KR) system. • So, tools to aid in airport design, and real-time intrusion detection and recovery can be based on a KR system? • Yes. • Will such a system be able to justify its decisions with explanations? • Yes.

  12. Real-Time Incursion Detection and Recovery • Same model (with concepts about airplane, trucks, etc. having positions, moving on surfaces, etc. • Rules about incursions: If a plane is moving on a mixed-use runway, and another vehicle is on a surface that crosses it, then you have a Possible-Collision Risk. • Find mitigation instances for the risk, sort them for relevance, and present them.

  13. Accountability • Systems should know what’s going on. • Inferences can be traced and explained. • People hate systems that act like black boxes, especially when they misbehave. Sophisticated explanations and justifications give users confidence

  14. Agent Design for Airport Planning

  15. The Real-Time Incursion Process • Real-Time data is read. • Risk rules are applied and risks found (mostly by reconstructing the original risk analysis that led to covering strategies). • The strategies whose actions mitigate the risk are found and presented to the controller. • The controller assesses the situation and makes selections. [Could this be done automatically?] • How to present multiple incursion and their mitigation strategies is, of course, a human factors problem.

  16. USC Intrusion Management Intelligent, Extendible Tools • USC IM - Next Wave safety application • Capturing and organizing common knowledge • Using deductive power to solve problems • Aids for planning and improving airports • Aids for real-time detection and recovery • Using the same knowledge base for each activity
