This paper surveys pricing mechanisms used by government agencies to manage congestion, as well as highlights the many political and social issues that have to be addressed in order to implement a pricing mechanism. This survey was undertaken in order to be able to understand how congestion pricing could be used to help manage airspace capacity. This is an(More)
This paper documents results we obtained from meta-simulation experiments which included both dynamic airspace configuration (DAC) and Traffic Flow Management (TFM) automated decision making. The DAC decision making operated in the Chicago Center and the TFM decision making was national airspace system (NAS) wide. Our results give preliminary indications of(More)
This paper describes a preliminary study of user gaming concepts embedded in the traffic flow management. We design multiple experiments to evaluate the national airspace system (NAS) when both advanced traffic flow management (TFM) and user decision-making models are implemented. Special attention is directed at quantifying the impact of TFM user gaming.(More)
Presents a collection of slides from the author's conference presentation. ⧁ Most applications require simulator enhancements • Development resource requirements are easy to underestimate ⧁ We have used our NAS-wide simulator for a wide variety of applications ⧁ What worked? • Segregating core simulation from decision(More)
First, this paper examines fundamental issues that arise when evaluating the sensitivity of decision support tool (DST) performance to trajectory prediction (TP) accuracy. Second, this paper presents a preliminary experiment, showing that variations in TP accuracy can substantially affect performance of a traffic flow management (TFM) DST due to differences(More)
