Trajectory Clustering for People's Movement Pattern Based on Crowd Souring Data [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
With the increasing availability of GPS-enabled devices, a huge amount of GPS trajectories recording people's location traces have been accumulated and shared freely on the Web.

Trajectory analysis at intersections for traffic rule identification

open access: yesGeo-spatial Information Science, 2021
In this paper, we focus on trajectories at intersections regulated by various regulation types such as traffic lights, priority/yield signs, and right-of-way rules.

Recording fine‐scale movement of ground beetles by two methods: Potentials and methodological pitfalls

open access: yesEcology and Evolution, 2021
Movement trajectories are usually recorded as a sequence of discrete movement events described by two parameters: step length (distance) and turning angle (bearing). One of the most widespread methods to record the geocoordinates of each step is by a GPS

Automatic Generation of Road Maps from Low Quality GPS Trajectory Data via Structure Learning

open access: yesIEEE Access, 2018
Up-to-date road maps are critical for intelligent transportation applications, such as car navigation and route planning. Unfortunately, conventional road map generation through surveying and image digitizing is labor intensive and time consuming ...

Patterns in Mongolian nomadic household movement derived from GPS trajectories [PDF]

open access: yes, 2020
This paper presents an approach for a quantitative analysis of movement patterns of nomadic households based on GPS trajectories. We distributed GPS loggers to 400 Mongolian herder households who carried them over a 9-month period, continuously recording
