A SYSTEM FOR VEHICLE DATA PROCESSING TO DETECT SPATIOTEMPORAL CONGESTED PATTERNS: THE SIMTDAPPROACH

摘要

In the German project simTD (“Sichere und Intelligente Mobilit?t- Testfeld Deutschland”) theso-called Car2X-technologies support the generation of traffic related vehicle data for furtheruse at the infrastructure by traffic control centres. The research lab DRIVE-Centre in thefederal state of Hessen has been prepared to process the simTD vehicle data based onKerner’s three-phase traffic theory (e.g, [1]-[4]). Within this project, a system for dataprocessing of vehicle data and their fusion with the traffic information reconstructed by themodels ASDA/FOTO (devoted to the reconstruction of congested traffic patterns based onKerner’s three-phase traffic theory) based on detector data has been developed. In this paper,the system approach and practical methodology for the data fusion of FCD (“Floating CarData” sent by the Car2X-vehicles) and ASDA/FOTO will be presented. Furthermore, theimplemented GUI in the federal state of Hessen and some real measurements will bediscussed.
