Modeling Air Traffic Situation Complexity with a Dynamic Weighted Network Approach

Hongyong Wang, Ziqi Song, Ruiying Wen
2018 Journal of Advanced Transportation  
In this paper, we propose a new approach for the measurement of air traffic situation complexity.  ...  This approach considers the effects of both airspace and traffic flow and objectively quantifies air traffic situation complexity.  ...  On the other hand, piecewise functions are used to guarantee that, for traffic situations with the same spatial proximity, a larger spatial approaching rate (larger divergence) corresponds to smaller situation  ...

Ad Hoc Participation in Situation Assessment

Christian Reuter, Thomas Ludwig, Volkmar Pipek
2014 ACM Transactions on Computer-Human Interaction  
This article presents a study on how emergent "collaboration needs" in current work of response teams located on-site and in the control center could be supported by mobile geo-collaboration systems.  ...  Such informal practices can facilitate ad hoc participation of units in situation assessment, but this may lack overall situation awareness.  ...  ACKNOWLEDGMENTS The project InfoStrom is funded by a grant from the German Federal Ministry for Education and Research (No. 13N10712).  ...

Learning situation-dependent costs

Karen Zita Haigh, Manuela M. Veloso
1998 Proceedings of the second international conference on Autonomous agents - AGENTS '98  
We present the development and use of these rules for a robotic path planner. We present empirical data to show the e ectiveness of Rogue's novel learning approach.  ...  Our learning approach is applicable for any planner operating in any physical domain.  ...  Planners can then use these situation-dependent rules to make better decisions.  ...

Situation awareness systems, states and processes: a holistic framework

Jonas Lundberg
2015 Theoretical Issues in Ergonomics Science  
Based on an analysis of four enactments of Air Traffic Control situations, the paper argues that what is domain-characteristic may not characterise all situations in a domain.  ...  This paper argues that state, system, and process descriptions of situation awareness (SA) are interdependent. Based on SA research from the last 30 years, the paper proposes a holistic SA framework.  ...  The tower simulation recordings were also supported by Tobii Technology.  ...
