   Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Clas Rydergren; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; map matching; trajectory pattern mining; closed contiguous sequential pattern mining; trajectory pattern visualization; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : A large proportion of movement in urban area is constrained to a road network such as pedestrian, bicycle and vehicle. That movement information is commonly collected by Global Positioning System (GPS) sensor, which has generated large collections of trajectories. LÄS MER

3. 2. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

   Sammanfattning : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.
