Analysis of Pedestrian Recognition by the Vehicle Driver
Šlapal, David ; Kropáč, František (referee) ; Maxera, Pavel (advisor)
This diploma thesis deals with vehicle driver’s recognition of pedestrian in different driving and light conditions. The introductory part will be devoted to basic theoretical knowledge. The attention is focused on safety measures to prevent accidents between pedestrians and vehicles. The main part will be devoted to the pedestrian´s visibility from the driver´s point of view during reduced visibility on roads in darkness. The practical part of this work summarizes the results of the experiment using the selected vehicle and chosen participants. During this experiment, the distance necessary for detection, recognition and identification of the pedestrian will be measured, to stop the vehicle safety in time or to avoid an obstacle on the road.

Analysis of the Causes of Traffic Accidents Involving Vehicles and Pedestrians on Selected Pedestrian Crossings
Šimáková, Aneta ; Ptáček, Petr (referee) ; Maxera, Pavel (advisor)
A master’s thesis deals with a problem of traffic accidents on pedestrian crossings. A theoretical part describes causes and following responsibilities of all participants of the traffic accident. Furthermore, the theoretical part analyzes a traffic system and its individual parts. A practical part of this thesis describes all measuring tools used for collection of data during the analysis. The data was obtained during a real traffic on chosen pedestrian crossing in Brno A tool used for analysis is called eyetracer. Furthermore, an evaluation of collected data and following analysis were carried out. Eventually, results were compared with reports about accidents which happened on chosen pedestrian crossings.

Differences in the Driver's Behavior when Driving through a Pedestrian Crossing at Night and in the Daytime
Vlasák, Jaroslav ; Semela, Marek (referee) ; Maxera, Pavel (advisor)
The theoretical part of the diploma thesis focuses on the drivers reacting on a pedestrian crossing during the day and the night. A particular attention is paid to all the factors that can influence drivers' behaviour while driving through a pedestrian crossing. The influence of the behaviour by these factors often causes car accidents with pedestrians. One of the basic techniques is to analyze the behavior of the driver in the optical perception of stimuli that affect the optical response. Eyetracker is used to measure the optical responses. This device monitors changes of the angle of a driver's view, navigation of a driver and the driver's reaction on different stimuli while driving. The practical part of the thesis deals with an analysis of the drivers' behaviour while driving through a pedestrian crossing during the day and during the night. Twelve drivers took part in the day measurement of driving through the pedestrian crossing in Brno. Night measurement was taken place in Břeclav and Lednice with the attendance of seven drivers. During the ride are monitored the optical reactions of drivers on various impulses with the use of a special device Eyetracker.

Analysis of driver’s conduct during solving of situations associated with pedestrians crossing the road
Maxera, Pavel ; Kolíbal, Zdeněk (referee) ; Rábek, Vlastimil (referee) ; Kledus, Robert (advisor)
The doctoral thesis analyses driver’s conduct while solving situations associated with crossing of pedestrians across the road in cases of various design of pedestrian crossings and at different conditions. The thesis deepens the knowledge of the human factor impact on the occurrence of a traffic accident involved vehicle and pedestrian and thesis also complements knowledge for the needs of the analysis of traffic accidents, especially in solving the pre collision phase and at assessment of possibilities for collision prevention by involved participants. The thesis deals with driver’s conduct, various models of the conduct as well as the thesis focuses on the visual perception, the process of information processing, the driver’s conduct and the reaction time. In terms of the solution suitable types of experiments were designed and implemented. Based on performed measurements a method of processing and evaluating data on drivers’ conduct was found as well as more significant data set was obtained for a detailed analysis of drivers' conduct in different driving situations. The assessed quantities of drivers' conduct were analysed with respect to the dangerousness of driving situations. For these purposes, the categories of the dangerousness of driving situations were defined (situations completely safe, with increased danger, dangerous and critical), into which the analysed driving situations were subsequently included. To enable the quantification of this classification of situations into the categories of the dangerousness, the coefficient of the dangerousness (so called K) was defined. From the detailed analysis of the obtained data, the limit values of this coefficient were determined, and these were subsequently verified using data from the solution of real traffic accidents. Concurrently the analysis verified the suitability of using this hazard coefficient in the analysis of traffic accidents, especially for a detailed assessment of the possibilities of collision prevention.
