Evaluating intervention strategies for metering in the presence of trajectory uncertainty

Presents a collection of slides from the author's conference presentation. • These results illustrate the trade-off between early and late intervention in the context of TBM - ABESS: • An intervention strategy with a ramped intervention threshold of 50 seconds per 100 NM minimizes the cost of speed intervention (as defined by the squared speed) - TMA: • An early distributed delay is clearly worse than both evenly distributed delay and “delay discounting” • Evenly distributed and “delay discounting” are similar Differences between them may be due to model effects • Next Steps - Explore other intervention strategies and costs - Model speed adjustment and vectoring together
