Trajectory Outlier Detection on Trajectory Data Streams

open access: yesIEEE Access, 2020
The detection of abnormal moving on trajectory data streams is an important task in spatio-temporal data mining. An outlier trajectory is a trajectory grossly different from others, meaning there are few or even no trajectories following a similar route.

Stacking-based visualization of trajectory attribute data [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2012
Visualizing trajectory attribute data is challenging because it involves showing the trajectories in their spatio-temporal context as well as the attribute values associated with the individual points of trajectories.

Data-driven trajectory smoothing [PDF]

open access: yesProceedings of the 19th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2011
Motivated by the increasing availability of large collections of noisy GPS traces, we present a new data-driven framework for smoothing trajectory data. The framework, which can be viewed of as a generalization of the classical moving average technique, naturally leads to efficient algorithms for various smoothing objectives.

A Data Augmentation Algorithm for Trajectory Data

open access: yesProceedings of the 1st ACM SIGSPATIAL International Workshop on Methods for Enriched Mobility Data: Emerging issues and Ethical perspectives 2023, 2023
The growing prevalence of location-based devices has resulted in a signi!cant abundance of location data from various tracking vendors. Nevertheless, a noticeable de!cit exists regarding readily accessible, extensive, and publicly available datasets for research purposes, primarily due to privacy concerns and ownership constraints.

Estimating Link Flows in Road Networks With Synthetic Trajectory Data Generation: Inverse Reinforcement Learning Approach

open access: yesIEEE Open Journal of Intelligent Transportation Systems, 2023
While traffic volume data from loop detectors have been the common data source for link flow estimation, the detectors only cover a subset of links. These days, other data sources such as vehicle trajectory data collected from vehicle tracking sensors ...

Maintaining trajectory privacy in mobile wireless sensor networks [PDF]

open access: yes, 2013
Mobile wireless sensor networks (MWSN) is a subdomain of wireless sensor networks in which sensors and/or sinks are mobile. In this study, we propose a scheme for providing trajectory privacy of mobile sink nodes.

Semantic Trajectories Data Models [PDF]

open access: yes, 2020
Semantic trajectories is a major paradigm for the representation of movement data, complementary to spatial trajectories. In this article, we introduce key concepts, focusing in particular on the structural properties of semantic trajectories. Hence, we discuss a possible taxonomy of semantic trajectory models, based on their purpose.
