Influence of Steering Wheel Holding Techniques on Length of Driving Maneuver
Kašpar, David ; Kadula, Lukáš (referee) ; Mikulec, Roman (advisor)
This master’s thesis deals with the position of the hands on the steering wheel and its impact on the driving manoeuvre time. In the theoretical part, the correct sitting position of the driver, his seat and steering wheel settings were described. Furthermore, the analysis of the initial positions of the palms on the steering wheel was carried out as well as the positions that are recommended for quiet driving on the highway. These positions were analysed in terms of the ability to turn the steering wheel and to provide a range of turning in given positions. For the experimental measurements, a questionnaire for the passenger vehicle drivers was created. The responses were evaluated to construct the most common hand positions on the steering wheel. From the selected positions, test drives were conducted to determine the required time for manoeuvring or the time required for change of hand positions on the steering wheel to perform the manoeuvre.

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.

Impact of Drivers' Working Regimes in Freight Road Transport on Transport Safety
Máša, Vojtěch ; Novotný, Jiří (referee) ; Libertín, Josef (advisor)
Working arrangements are restrictive limits for drivers important for both motor carriers and drivers. Have a major impact on the logistical arrangements of manufacturing companies that transport their goods by road. Failure to comply with these limits, is recently one of the major problems in road transport and leads to unfair competition between road hauliers. Carrier's failure to obtain such social legislation crucial competitive advantage. Recently the problem devoted much time from the perspective of politicians. States, violations of social legislation by the carrier and the driver severely punished and often the articles we read on the operating modes of drivers and their associated hazards of freight transport, road safety hazard, danger for drivers of cars. For 10 years devoted to the issue and participate in the creation of training materials on the subject of Logistics and. In my work I wanted to examine the issue of working arrangements drivers from professional point of view - how the limits are set and working arrangements whether they comply with road safety. Next, consider the statistics of accidents in the CR in relation to drivers' working arrangements and to propose changes that would contribute to the improvement of social legislation in relation to road safety.

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.
