Cyclists perception in road traffic
Janošíková, Denisa ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
This thesis deals with cyclist behavior in real road traffic — the thesis aimed specifically at visual perception of the situation behind the cyclist before turning and lane changing. The cyclist's behavior before turning and lane changing is analyzed concerning visual perception, the time of head-turning, and signaling the direction change. The distance from the intersection, where these actions began, was also evaluated. The measurement was conducted in real rod traffic in the Valašské Klobouky town. The average times necessary for visual inspection of the situation behind the cyclist ranged from 0.97 seconds to 1.50 seconds. The average values of the distance from the intersection, where signaling of the direction change began, ranged from 41 m to 51 m. Results can be used in the field of accident analysis or education.

Women behavior in road traffic
Gajdůšková, Vendula ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
This thesis is focused on women's behavior in road traffic, specifically the visual perception of the situation behind the vehicle before initiating, during, and after completing the selected driving maneuvers. Based on the analysis of the current state, experimental measurements were proposed to be conducted in real traffic conditions in Zlín and its surrounding area. The visual perception during the analysis of the situation behind the vehicle, eye movement strategies, and their durations were analyzed. The average fixation durations ranged from 0.28 seconds to 0.47 seconds. The results showed that the longest fixation durations were recorded when stopping before an intersection and the shortest when turning right. The study also revealed differences in eye movement strategies and behavior between men and women. It was shown that women focus more on the situation in front of the vehicle than on the situation behind it. The results of this work can be utilized in the analysis of road crashes and contribute to the improvement of driving school training.

Checking of the Situation Behind the Vehicle
Jánošík, David ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
The diploma thesis deals with the issue of controlling the situation behind the vehicle. The first part of the thesis summarizes the knowledge about drivers, their reaction time and vehicle response, the construction characteristics of vehicles designed to control what is happening behind the vehicle, and the possibilities of measuring the duration of glances in the form of eye tracking. The analytical part contains an analysis of the duration of glances in the rear view mirrors depending on the mirror, the situation and also the driving manoeuvre during the day time. The data was obtained from video recordings of 12 drivers in normal traffic conditions. The duration of the saccades and fixations of glances was evaluated depending on the mirror used, in individual situations and also for selected driving manoeuvres. The conclusion of the analytical part is devoted to the comparison of the duration of glances during selected driving manoeuvres when exposed to stimuli as well as to the comparison of the differences in individual age groups of tested drivers.

Delineation of experimental ECG records
Bucsuházy, Kateřina ; Ronzhina, Marina (referee) ; Vítek, Martin (advisor)
This master thesis deals with QRS complex detection and ECG delineation. The theoretical part of this work describes wavelet transform, some of QRS detection approaches and some of ECG delineation approaches. For algorithm realization in Matlab is used redundant dyadic discrete wavelet transform. Algorithm is designed for experimental electrocardiograms of isolated rabbit hearts and it is evaluated through manually determined references.

Reaction time of Persons Influenced by Alcohol
Ohera, Adam ; Bucsuházy, Kateřina (referee) ; Semela, Marek (advisor)
This thesis is focused on the issue of reaction time of those people who are affected by alcohol. The thesis is divided into two main parts, the first part is focused on the research of the present state and it submits the theoretical background related to the topic of this thesis. The second part describes both the experiments related to the reaction time of the people affected by alcohol and the evaluation of the results of such measurements.

Analysis of the Reaction Time of a Driver Influenced by Selected Distracting Stimuli
Černohorská, Magda ; Semela, Marek (referee) ; Bucsuházy, Kateřina (advisor)
The diploma thesis deals with the analyses of food consumption influence on driver´s perception reaction time. It describes the food and drink consumption while driving, factors influencing driver´s performance, activities disturbing the driver, foreign researches and studies aimed at distracting stimuli. Practical part of the thesis is focused on driving tests of chosen driver of certain age group in current traffic, interpretation and evaluation of reaction times while driving with no distracting stimuli comparing to driving influenced by food consumption. All the data are concluded in the summary where it´s confirmed that reaction times are significantly prolonged when drivers have a snack while driving a vehicle.

Influence of selected factors on driver behavior
Křemenová, Tereza ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
The diploma thesis deals with the analysis of the influence of certain types of intersections and at the same time the time of day. The theoretical part describes the introduction to the factors affecting the driver when driving a motor vehicle. Furthermore, the work defines road junctions by law, types of road junctions and research on the issue of road junctions. The practical part of the diploma thesis is devoted to the evaluation of the total number of primary and secondary views of certain types of intersections and their average duration of day or night. At the same time, it evaluates the first direction of view according to the type of road (secondary road / main road) and the subsequent direction of travel. The obtained data are evaluated in the chapter discussion / analysis of results. The evaluated data in the first part showed that the secondary views have a shorter average duration compared to the average duration of the primary views. In the second part, the results of day and night were identical only at the roundabouts, when the drivers made the first direction of view to the left.

Analysis of Selected Distractive Stimuli on the Driver Attention
Bucsuházy, Kateřina ; Rybka, Jindřich (referee) ; Mičunek,, Tomáš (referee) ; Semela, Marek (advisor)
The dissertation thesis focuses on the problem of driver inattention as one of the main factors contributing to the traffic accidents occurrence. The importance of this topic has been introduce on the basis of the literature review. The theoretical analysis includes terminology in the field of accident analysis related to the topic of this dissertation thesis. Existing methods for driver behavior analysis have been introduced as well as the selected resuls of existing research studies focused on the driver inattention. Research gaps have been identified on the basis of the research review, on some of them has been focused this work. The defined problem situation points to the need to find and verify the relevant modern methods for analysis of driver inattention, respectivaly influence of selected distracting stimuli on the stages of driver information processing. The series of measurements also provides quantified data, especially with regard to the perception duration of selected distracting stimuli.

Driver perception in different conditions
Seriš, Jozef ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
This diploma thesis is focused on the comparison of perception of traffic signs and advertising areas in two different conditions day and night with focus on visual distraction of the driver. The introductory part deals with the analysis of the current state of the elements acting on the driver with an emphasis on mental processes and the senses of drivers affecting traffic safety. The analytical part draws on the videos from driving tests, the whose goals was to monitor the optical reactions of drivers. The resulting data were evaluated with goal to determine the time consuming views of the drivers on individual elements and the compared in different conditions. The last chapter includes the interpretation of the results of the analysis with suggestion of their use to increase traffic safety.
