  • Evaluation of En Route Performance Measures

    Principal Investigator(s) 
    Ball, Michael O.
    Lovell, David J.

    Federal Aviation Administration

    This project is a joint effort between researchers at the University of Maryland and the University of California, Berkeley. The goal is to develop methods to determine what causal factors contribute to the en route inefficiency of commercial flights in the United States, and the extent to which each of those causal factors is responsible.



  • National Traffic Management Log Analysis

    Principal Investigator(s) 
    Lovell, David J.

    Federal Aviation Administration

    The goal of this project is to generate metrics and visual dashboards related to the National Traffic Management Log (NTML). The NTML is a repository of data related to the execution, by the FAA, of a wide variety of traffic management initiatives, to control air traffic in the National Air System. Their objectives are to ensure safety and diminish congestion, and they use initiatives such as Ground Delay Programs, Airspace Flow Programs, and Miles-In-Trail restrictions, among others, to accomplish these objectives.



  • Optimization and Prediction for Collaborative Trajectory Options

    Principal Investigator(s) 
    Ball, Michael O.
    Lovell, David J.

    National Aeronautics and Space Administration

    This project is a subcontract to Metron Aviation, Inc. The goal of the project is to help determine how the FAA should define and manage a new paradigm in aviation congestion management called the Collaborative Trajectory Options Program (CTOP). In this program, carriers submit, for each scheduled flight, a menu of possible flight plans that they would be willing to use for that flight, with an accompanying measure of preference for each plan. Armed with this information, the FAA can jointly optimize the allocation of airspace resources to these flights by selecting from amongst these plans. The FAA accomplishes its mission of preserving safe operations with as little congestion as possible, and carriers are allowed collaborative input into the decision-making process, without unlawful collusion, maintaining the propriety of their data and plans, and without the FAA having to pick winners and losers.
