Academic literature on the topic 'Analýza jízdy'

Shrnutí Částice obsažené ve výfukových plynech spalovacích motorů jsou jejich pro lidské zdraví nejvíce škodlivou složkou. Se snižující se celkovou hmotností emitovaných částic se zvyšují nároky na její měření, které vyžaduje plnoprůtočný ředicí tunnel nebo proporcionální vzorkovač s ředěním části toku s rychlou odezvou. Pro umožnění takových měření během jízdy vozidla a v méně vybavených laboratořích bylo vytvořeno nízkonákladové zařízení pro proporcionální vzorkování výfukových plynů. Zařízení využívá dvojici regulátorů hmotnostního průtoku, z nichž jeden dodává proměnlivé množství ředicího vzduchu do miniaturního ředicího tunelu, a druhý udržuje konstantní průtok směsi ředicího vzduchu a výfukových plynů přes filtr, na který jsou částice vzorkovány. Výsledky naměřené tímto systémem během dynamických jízdních cyklů jsou, po korekci systematického rozdílu, v rozmezí faktoru dvou od výsledků gravimetrické analýzy vzorků odebraných z klasického plnoprůtočného ředicího tunelu.

This paper deals with the preparation, implementation, and basic assessment of the motorists’ response times to simple optical and complex – other than optical - stimuli. Driving tests conducted partly under regular traffic conditions and partly on a test track are completed with findings on how drivers react when they use their phones during driving. Knowledge of the actual technically achievable reaction time is necessary in performing analyses and consequent assessments of the causes and developments of road traffic accidents.

V rámci této práce byl navržen a implementován systém pro analýzu dopravy z videa. Tento system umožňuje detekovat, sledovat a klasifikovat automobily. Systém je schopný detekovat pruhy z pohybu projíždějících automobilů a také je možné určit, zdali daný automobil jede v protisměru. Rychlost projíždějících automobilů je také měřena. Pro funkčnost systému není vyžadován žadný manuální vstup nebo kalibrace kamery, jelikož kamera je plně automacky zkalibrována pomocí úběžníků. Navržený systém pracuje s velkou přesností detekce, sledování a klasifikace automobilů a také rychlost automobilů je měřena s~malou chybou. Systém je schopný pracovat v reálném čase a je aktuálně využíván pro nepřetržité online sledování dopravy. Největším přínosem této práce je plně automatické měření rychlostí projíždějích vozidel.

This project aims to create a mobile application for iOS devices that provide valuable information about user's car rides. Needed data are obtained by ELM327 located in OBD-II scanner which can communicate with the car. Obtained data are analyzed using table of limits. The application informs riders about their driving mistakes and giving them tips how to fix them. Trips can be saved and exported in the form of logbook. In addition application includes diagnostic functions that can be found in every other diagnostic application.

In this thesis entitled ,,Analysis of motion of the bicycle when riding in a straight line”, I deal with the history of the bicycle, classifications and descriptions of the various parts of the bicycle and the analysis of accidents. The main objective is to analyze the movement of cyclists (bicycle) in a straight line in the implementation of tasks, typical for him - pedaling, showing a change in direction, or looking back for him. In conclusion evaluation, which can then be used in the processing of judicial opinions by experts.

The objective of this master thesis is to design and develop a real-time storage system for geographic data from driving school trips. The system provides tools for analysis and evaluation of practice trips. This system is an extension of the DoAutoskoly.cz project which is described in the text. The next part contains an introduction to geographical data, spatial data and available databases with spatial extensions. The understanding to spatial databases is very important for the system design, an explanation of a solution for a database layer and implementation of major parts. Solution for a graphical view of the results and possible extensions of the system are described in the last part of this thesis.

The present apparatus for the technical analysis of road accidents has no well-integrated information, recommendations or procedures of how to solve comprehensively the analysis of road accidents involving vehicles equipped with stabilization system of driving dynamics. The problem in the investigation of a vehicle movement in a curve is the ignorance of the contributions of vehicle dynamics intervention of the electronic stability system. Although some of the simulation software used in the analysis of road accidents makes it possible to take into account the modelled vehicle movement impacted by a stabilization system in the examined process, but the experts do not know what parameters should be entered in the numerical models of stabilization system in a computer programme. Therefore, the thesis investigates the issue of the expert analysis of vehicle riding and braking in a general spatial curve at speeds exceeding 50 kph with simultaneous examining the impact of electronic stability system chassis on vehicle driving dynamics. The thesis first deals with the solutions based on classical analytical methods, then dwells on experimental measurements in real conditions on testing grounds and, finally, addresses the use of computer simulation software in expert practice. Nevertheless, it is important to realize that no computer simulation software can be an absolutely unambiguous solver, and it is not enough to generate a computer simulation, but so obtained results should be evaluated and justified technically. Road accident analyst needs to know the impact of vehicle electronic stability control systems on vehicle movement. The thesis investigated the mutual relationship between the vehicle speed limit in a curve specified by analytical calculation and the vehicle speed in a curve experimentally detected by measuring the parameters of driving dynamics of a vehicle equipped with electronic stability system. The impact of selected electronic stability control systems of the chassis on the vehicle movement in the investigated processes in the curve was detected and quantified by driving experiments. Finally, the input values of significant quantities of computational models of the ESP simulation programs were found consistent with the results of experimental measurements in defined curves for the vehicles equipped with electronic stability systems. The results of the thesis can be used both in the expert and in the teaching activities.

This diploma thesis Analysis of selected manoeuvres of bicyclists deals with the history and development of the bicycles, further their division of, construction, analysis accident and national legislation in the theoretical part. The practical part of the master thesis is devoted to the measurements of the bicycles. Specifically, it is about acceleration, deceleration, transverse movement, ride in the curve and looking back before changing the direction. For measuring are selected different type of bikes with different construction. The results of individual measurements are evaluated in the end of the diploma thesis.

Practical measurements with bicyclists is in the second part of this thesis. Cyclists performed deceleration on three surfaces, acceleration and a manoeuver, in which cyclist looked behind himself before changing the direction. The evaluation of all measurements and comparison with other similar works has been made in the last chapters.

The diploma thesis titled Interpretation of traffic accident analysis results in relation to related legal decision deals with the interpretation of legal decisions accidents with not giving right of way. The main goal of this thesis is to find an established line for assessing culpability for comparable accident situations. Before the analysis of the 230 court rulings measurement is performed to estimate the distance an speed, because it is closely connected with right of way. In the context of theoretical part is characterized by a right of way, an expert in criminal proceedings, the road traffic regulations, penalties and the factors that influence us while driving. The analytical part draws on 230 court rulings and 5 expert opinions provided by the Institute of Forensic Engineering of the Technical University in Brno. Conclusion of the analytical part an established threshold for assessing culpability for comparable accident situations is found.
