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.

Determination of duration that driver needs to assess the situation behind the vehicle in course of turning or overtaking manoeuvres.
Belák, Michal ; Rábek,, Vlastimil (referee) ; Kolíbal, Zdeněk (referee) ; Semela, Marek (advisor)
The dissertation thesis deals mainly with determining of the duration that driver needs to assess the situation behind his vehicle at manoeuvers of turning and overtaking, based on the measurements made in real road traffic. These are common and frequent driving manoeuvers, which the driver performs while driving the vehicle in regular road traffic. For their safe execution the driver needs to have sufficient amount of information about the situation around the vehicle and especially behind the vehicle. This information can driver usually gain from devices for indirect vision, most often rear view mirrors. The time thus defined, suitable e.g for the needs of forensic engineering applications for the analysis of road accidents, has not been studied in detail yet. For the purpose of its determination, therefore, an extensive analysis of the current state of problematics related to the indirect vision from the vehicle was carried out. There were formulated influences on the time duration and with this related characteristics of humans as a part of the driver-vehicle-environment system in the thesis. The characteristics of human perception were investigated and the problematics of reaction time was discussed. Existing research focused on the duration of rear view mirrors glances was analyzed and possible methods of its measurement in detail were presented by author. Based on this, an experiment was designed and realized, the time necessary for rear view mirror glances was defined by the author. The results enable to quantify the time that the driver needs for assessing the situation behind the vehicle in connection of turning, overtaking and other driving manoeuvers when the driver needs to change the driving direction. The conclusions showed that the time needed to evaluate the situation behind the vehicle by means of the rear-view mirrors does not normally exceed duration 1 second.

Checking of the Situation Behind the Vehicle
Perničková, Tereza ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
This diploma thesis deals with the control of the situation behind the vehicle. The theoretical part of the thesis summarizes the knowledge about the transport system, the reaction time and the individual phases, including the factors influencing the reaction time and the possible methods of its measurement. Further, there are issues of vision from the vehicle and the rules of safe driving. Explanation is the eyetracking method, the types of these devices, and the methods of visualizing the data obtained from the records. In the analytical part are drawn from data recorded video. There are testing route, testing device, testing vehicle and information about testing drivers. The frequency and length of the individual components of the mirror views were evaluated depending on the selected mirror even without dependence from the data obtained.

Usual time and frequency of mirrors and dashboard observation by the driver
Krejčí, Vojtěch ; Sedlák, Robert (referee) ; Bradáč, Albert (advisor)
The thesis deals with the analysis of the usual time and frequency of vehicle mirrors and dashboard observation. Within the theoretical part are summarized the current knowledge of the visual distraction of the driver, or circumstances which affect the conduct and behavior of the driver while driving. Furthermore there is a closer approximation and characterization of devices for recording the driver's eye movement, which is used during the measurement of the usual time of observation. This data is used in the experimental part of the thesis. The results were processed and statistically analyzed to determine the usual time of mirrors and dashboard observation. Conclusions done from the measurement results are contained in the last chapter, which also evaluates contribution of this work to practical use in the field of analysis of road accidents and to improve safety on our roads.
