Public Transportation Lines classification by GNSS data
Pizur, Jaroslav ; Lázna, Tomáš (referee) ; Jílek, Tomáš (advisor)
The subject of this thesis is digitalization of bus transportation. The input is represented by a sequence of GNSS data which are transformed to the OpenStreetMap format. Doing so, it is enriched by the information OpenStreetMap format provides and it gains its positional advantages as well. Then this thesis deals with ways by which one can detect bus lines from this general sequence of GNSS coordinates. A bus line is recognized as a repeating trajectory, which satisfies criteria derived from its expectable or defined characteristics. A few clustering solutions are proposed and tested for their performance. On the basis of this testing, there is one solution chosen as the best performing one, to be the proposed solution of this thesis. The overall output will therefore be formed by automatic mapping of bus lines with no theoretical area limit and with minimum manual intervention needed. It lays the foundations for various intelligent real-time processes to be implemented as well as allowing for infrastructure to be processed for the statistics purposes or urban planning.
Simulator Of Network Communication With Map Interface For Ns3
Benedikt, Jan
The work deals with the description of creating a network simulator with a map interfacefor Network Simulator 3. The first part of the work deals with the existing solution Network Animator(NetAnim) and based on the submitted requirements, justifies the intention to create a new simulationinterface. The following is a description of the technologies and standards used to create a newinterface. The main part of the work is a description of the development of the simulator itself.The last part of the work presents the developed interface for analysis of simulation results from theNetwork Simulator 3 (NS3).
