A Trajectory Collaboration Based Map Matching Approach for Low-Sampling-Rate GPS Trajectories

open access: yesSensors, 2020
GPS (Global Positioning System) trajectories with low sampling rates are prevalent in many applications. However, current map matching methods do not perform well for low-sampling-rate GPS trajectories due to the large uncertainty between consecutive GPS

Topological Path Planning in GPS Trajectory Data [PDF]

open access: yesSensors, 2016
This paper proposes a novel solution to the problem of computing a set of topologically inequivalent paths between two points in a space given a set of samples drawn from that space. Specifically, these paths are homotopy inequivalent where homotopy is a

Traffic congestion prediction based on GPS trajectory data

open access: yesInternational Journal of Distributed Sensor Networks, 2019
Since speed sensors are not as widely used as GPS devices, the traffic congestion level is predicted based on processed GPS trajectory data in this article. Hidden Markov model is used to match GPS trajectory data to road network and the average speed of

Simplifying GPS Trajectory Data with Enhanced Spatial-Temporal Constraints

open access: yesISPRS International Journal of Geo-Information, 2017
Raw GPS trajectory data are often very large and use up excessive storage space. The efficiency and accuracy of activity patterns analysis or individual–environment interaction modeling using such data may be compromised due to data size and ...

A Two-Step Clustering Approach to Extract Locations from Individual GPS Trajectory Data

open access: yesISPRS International Journal of Geo-Information, 2016
High-accuracy location identification is the basis of location awareness and location services. However, because of the influence of GPS signal loss, data drift and repeated access in the individual trajectory data, the efficiency and accuracy of ...
