Intersection identification method based on sparse sampling GPS trajectory data [PDF]
Jisuanji gongcheng, 2019 Most of the current intersection identification algorithms are based on densely sampled Global Positioning System(GPS) trajectory data,using the direction of vehicle travel as the basis for intersection identification.However,the sparsely sampled GPS ...

A novel method for road network mining from floating car data
Geo-spatial Information Science, 2021 Vehicles have been increasingly equipped with GPS receivers to record their trajectories, which we call floating car data. Compared with other data sources, these data are characterized by low cost, wide coverage, and rapid updating. The data have become

Trend-Residual Dual Modeling for Detection of Outliers in Low-Cost GPS Trajectories
Sensors, 2016 Low-cost GPS (receiver) has become a ubiquitous and integral part of our daily life. Despite noticeable advantages such as being cheap, small, light, and easy to use, its limited positioning accuracy devalues and hampers its wide applications for ...

Discovering Corridors From GPS Trajectories
Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017 The increasing pervasiveness of GPS-enabled devices results in the collection of massive trajectories datasets. The vast amount of the generated location data is particularly difficult to be processed, interpreted and analyzed, due to its complexity. Nevertheless, in many cases a considerable number of moving objects share common paths and their whole ...

Is Medoid Suitable for Averaging GPS Trajectories? [PDF]
ISPRS International Journal of Geo-Information, 2022 Averaging GPS trajectories is needed in applications such as clustering and automatic extraction of road segments. Calculating mean for trajectories and other time series data is non-trivial and shown to be an NP-hard problem. medoid has therefore been widely used as a practical alternative and because of its (assumed) better noise tolerance.
