Computational Model and Analysis of Adaptive Traffic Lights
Terbr, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This thesis deals with the topic of adaptive intersections and the study of their influence on the flow of traffic and others. The work contains an analysis of currently used traffic detectors, an analysis of the main problems of classic intersections and the possibilities of their solution, followed by the design of the model, a description of the implementation and testing of the created model. The resulting model is created in the UPPAAL SMC software and is a system of timed automata communicating with each other. Testing is performed by comparing the results of tests of classical traffic lights with the results of adaptive traffic lights.

Vehicle Classification Using Radar
Gottwald, Vilém ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
Cílem této práce je rozpoznávání vozidel z radarových mračen bodů. Radar poskytuje informace o vzdálenosti a úhlu každého detekovaného cíle. Tyto informace lze převést do kartézského souřadnicového systému a získat tak 3D reprezentaci scény ve formě mračna bodů. V této práci jsou představeny stávající přístupy k rozpoznávání objektů v mračnech bodů. Metoda zvolená pro tuto práci spočívá v detekci objektů pomocí shlukování bodů a následné klasifikaci pomocí rekurentní neuronové sítě. Shluky bodů reprezentující objekty jsou vytvářeny z mračen bodů pomocí modifikovaného algoritmu DBSCAN. Z jednotlivých objektů jsou extrahovány příznaky, které jsou využity pro klasifikaci na různé typy vozidel pomocí neuronové sítě s dlouhodobou krátkodobou pamětí (LSTM). Pro trénování a vyhodnocení modelu byla vytvořena datová sada obsahující 57 345 anotovaných objektů. Vyvinutý model dosáhl na těchto datech 83% přesnosti metriky F1-skóre.

Trends in traffic accidents in the Czech Republic
Přibil, Martin ; Rychtaříková, Jitka (advisor) ; Fialová, Ludmila (referee)
Trends in traffic accidents in the Czech Republic ABSTRACT The aim of the study is to describe development of traffic accident rates in the Czech Republic for selected types of accidents in the road traffic. The study monitors development of accident rates and the most severe results of accidents between 1990 and 2010, and in a more detailed analysis of selected types of accidents between 1997 and 2010. Each type of accident is described by an absolute number of events, but also by comparative, structural and intensity indicators (parameters). Key words: traffic, road traffic, traffic accidents, traffic legislation, results of accidents, types of accidents

Issues of punishment for traffic offences
Klinovský, Karel ; Říha, Jiří (advisor) ; Krupička, Jiří (referee)
My thesis is focused on the issues of the punishment for traffic offences. This topic is actually in the spotlight of the social discourse since the relatively high number of tragic traffic accidents leads to the call for the solution of the anomy on the Czech roads. One of possible solutions is also a proportional use of the state repression using the legal tools of the criminal law. The goal of this thesis is an analysis of all the punishments applicable to the traffic offences and their de lege lata and de lege ferenda evaluation. In the first part of this thesis, I will define all kinds of transportation and their legal basis. This is necessary to put the road traffic offences into their proper place in the system of traffic related offences. Furthermore, I define the traffic offence and I also elaborate on which offences are traffic offences per se. My conclusion is that we should use more restrictive approach when it comes to listing the traffic offence. Later on, I modify this restrictive approach by adding the offences of reckless endangerment and obstruction of an official decision. As a part of this chapter, I also examine each offence in the context of their practical use and judicial decisions. The second part of this thesis is focused on the traffic offender. A very specific aspect of...

Issues of punishment for traffic offences
Hejda, Petr ; Říha, Jiří (advisor) ; Bohuslav, Lukáš (referee)
Road transport intervene in life perhaps each of us. Road transport play to journey to work, spending, medical care, no matter what already like drivers or co - driver or embarkment agents collective transport persons. At present is already quite common that the family personal two car, sometimes and more. S crescendo number vehicles in our households thereby fall and in - service on way, shoot up number enmity on roads, that often end in accident. Accident are also most frequent case offences or punishable act in road transport. Most accidents hasn't calamitous consequences, every day we're news media, especially television and internet, confronted with tragic aftermath serious accidents, that happen in all limits Czech republic. Unfortunately like general prevention these jerked - in - fillings and news malfunction so always speed ill general drift on the up grade of the number of accident stop. In his work first delimitate conception transport and road transport, try to explicandum punishable act in transport and will describe individual punishable act, that come into question like punishable act in transport. Most extensive volume of work will devoted punishments attempt life behind punishable act in road transport, when first carry out common expose punishments and purpose punishment and after it take...

Roads from the Perspective of the Environmental Law
Záluská, Isabela ; Žákovská, Karolina (advisor) ; Stejskal, Vojtěch (referee)
Roads from the Perspective of the Environmental Law Abstract In this Thesis, in light of amendment of the Line Act which severely dampens the concerned authorities' means of protecting the environmental public interests, I present a brief introduction to the environmental protection legislation in relation to roads, road construction and road traffic, showing the state of related present-day legislation and means through which the environmental public interests are protected during the road construction process as of today. To this end, I present a brief description of negative effects of roads on the environment, i. e. environmental fragmentation, land annexation, pollution of land and air, noise and artificial lighting. Next, I am showing an in-depth analysis of means through which the Czech law deals with these negative effects and which means of protection against them it offers. I show the road construction process, means of environmental public interest protection in this process and administrative-legal acts through which the means of protection are applied. Here I mostly focus on the environmental public interests in environmental protection, limiting the environmental fragmentation and protection of land. Next, I present the current state of legislation dealing with the negative aspects of road...

Reception and processing of visual information in traffic
Černochová, Dana ; Rymešová, Pavla (referee)
Reception and processing of visual information in traffic Mgr. Dana Černochová Abstract The theoretical part of this work deals with the visual perception of the driver. Special attention is paid to the perception of visual information in the whole range of the field of view. From psychological point of view, the term functional field of view is important, the construct taking into account not only perception, but also the attention. Its size depends on the amount of information which have to be processed at any given moment. Foreign literature uses the term "Useful field of view" under the abbreviation UFOV, german literature uses the term "nutzbares Sehfeld" under the abbreviation NSF. The experimental part of the work focuses on evaluating the changes of the visual perception in the range of the visual field in relation to age. For this the SET of 1361 people in age group from 18 to 90 years. In further subchapters the experiment is described where the secondary task was used as variable in order to find out whether the increased cognitive load affects the range of the useful field of view. For this experiment, the set of 645 people of age 18-90 years was used. The parameters of the visual perception in the situations with and without added secondary task were also monitored for the relationship to the...
