Optimal control of intersection signaling
Tinka, Petr ; Šoustek, Petr (referee) ; Kůdela, Jakub (advisor)
This master´s thesis is about the control of a traffic light. In the first, theoretical part of this work, a description of this problem introduce. The following is an overview of the optimization methods used for this problem. The practical part deals with the modeling of the network of traffic lights in program SUMO and the implementation of selected optimization methods on this. Finally, a comparison of results is made.

Simulator of Traffic Infrastructures and Situations
Švaňa, Petr ; Trchalík, Roman (referee) ; Kreslíková, Jitka (advisor)
The aim of this master's thesis is to develop a simulation system using the Siemens sX traffic controllers configurations. The system is composed of two separate applications. The first one uses the existing platform SUMO as a source of simulation data and is also used as a server. The second is a web-based application for creating and editing simulation situations and also for visualisation of simulation data from the server. The introduction to the topic of traffic engineering and the dynamic traffic control is discussed first. The description of the design and implementation of the simulation application directly follows. In the next part the design and implementation of the web-based application is discussed. The last part of the thesis describes the testing of the whole system.

Modern methods for intersection signaling control
Bartoš, Pavel ; Lacko, Branislav (referee) ; Kůdela, Jakub (advisor)
This diploma thesis deals with the optimal control of traffic lights at intersections. In the introduction, concepts are introduced and control methods are presented. Subsequently, Eclipse's SUMO software is chosen to create the model. Following the model of a real intersection, both layout and logic and traffic flows are created. The traffic flows itself are partially randomized. The control is performed using three green queue lengths and the evaluation is done by comparing the average and maximum waiting times. Pareto optimal points are thus selected. The first algorithm to obtain the optimal setting is a grid search. The second algorithm has been implemented by NSGA-II. The settings are compared with each other as well as with respect to the settings and the time window.

Analysis of vehicular ad hoc network
Varmus, Pavol ; Mašek, Pavel (referee) ; Kubánková, Anna (advisor)
This diploma thesis aims to study VANET (vehicular ad hoc network), to describe the theory of this networks and describe attributes of these networks and to set the starting point for practical part. Thesis includes VANETs possibilities, its signal transportation and description of routing protocols. Another goal was to familiarize program NS-3 and set up simulation models in its interface. The main output of the practical part is program which simulates vehicle movement in Brno city and set the communication module which is adapted to fulfill the most realistic transmission capabilities. Practical part is divided to two parts. The goal of the first one was to simulate basic communication in theorized unrealistic scenario and the second part was the more realistic scenario. Overall, throughout the practical part was tested a variety of attributes, such as mobility models, standards, routing protocols and other parameters that provided diversity in final results. All the results, which consisted of summary of basic transmission capabilities and reclassification of the applicability of those technologies in real world, are discussed in the summary of the simulations output.

Traffic Simulation Using Traffic Controllers
Dressler, David ; Trchalík, Roman (referee) ; Kreslíková, Jitka (advisor)
The aim of this master's thesis is to design an extension of the existing simulation system for designing traffic intersections. The required extension will allow the use of the Siemens sX traffic controllers. The introduction to the topic of traffic engineering, traffic controllers configuration and the dynamic traffic control is discussed first. The next part is dedicated to describing the implementation of the existing simulation system. The following chapter describes the use of the sX traffic controllers and also describes the design of the required extension of the existing simulation system, for a purpose of enabling the use of sX traffic controllers. This is followed by a chapter describing the implementation of this extension. The last chapter is devoted to testing the whole system in terms of functionality and performance. Finally, other possibilities for the future development are outlined.
