Modeling Relative Trajectory Costs for Airborne Trajectory Reroutes using Trajectory Option Sets
2021 IEEE/AIAA 40th Digital Avionics Systems Conference (DASC), 2021This paper proposes a novel approach to calculating Relative Trajectory Costs (RTC) as part of a new third-party tool to enable advanced airborne reroute operations. A selection of cost and delay factors, such as Crew, Fuel, Airspace Cost and Downstream Congestion, have been modeled to rank reroute options within the NextGen capability called the ...

Clustering motion trajectories via dominant sets
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In recent years, video surveillance systems stand out as an important research topic in the field of computer vision. Studies in this context usually focus on detecting common motion patterns in video sequences, determining unexpected motions or predicting possible future events.

Enumeration of complete set of flock patterns in trajectories
Proceedings of the 5th ACM SIGSPATIAL International Workshop on GeoStreaming, 2014In this paper, we consider the problem of mining the complete set of spatio-temporal patterns, called maximal-duration flock patterns (Gudmundsson and van Kreveld, Proc. ACM GIS 2006) from massive mobile GPS location streams. Such algorithms are useful for mining and analysis of real-time geographic streams in geographic information systems. Although a

Trajectory multi-Bernoulli filters for multi-target tracking based on sets of trajectories
2020 IEEE 23rd International Conference on Information Fusion (FUSION), 2020This paper presents two multi-Bernoulli filters on sets of trajectories for multiple target tracking. The first filter provides a multi-Bernoulli approximation of the posterior density over the set of alive trajectories at the current time step. The second filter provides a multi-Bernoulli approximation of the posterior density over the set of all ...

Dynamical polysystems defined on closed manifolds and consisting of finite number of smooth vector fields are considered. ω-limit sets of their trajectories are studied. If a polysystem consists of one vector field we have an old and difficult problem in the Qualitative Theory of differential equations.

Contextual grammars with uniform sets of trajectories
Fundam. Informaticae, 2005Summary: A uniformcontextual grammar with contexts shuffled along trajectories uses the same set of trajectories for each context. We prove that when the alphabet has at least two symbols, the nonuniform contextual grammars with trajectories are strictly more powerful than the uniform variant.

Efficient one-click browsing of large trajectory sets
Proceedings of the 22nd ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2014Traffic researchers, planners, and analysts want a simple way to query the large quantities of GPS trajectories collected from vehicles. In addition, users expect the results to be presented immediately even when querying very large transportation networks with huge trajectory data sets.
