Traffic analysis based on measured data of floating vehicles
Author: Riedel Marek
The aim of this study was to analyze GPS data measured by floating vehicles and to create a mathematical model of the area in form of oriented weighted graph. The paper describes data filtering, measured data refinement (map-matching algorithm), working dataset selecting (clustering algorithm), intersections finding (vertices), street finding (edges). Map sources for visual verification of the results are downloaded in the form of PNG images from Google Maps server. Results of data analysis and the mathematical model of the area is stored in the database.
