Quantitative Analyse der Komplexität von Knotenpunkten und ihr Einfluss auf die UnfallhäufigkeitGidion, Fritjof 27 September 2019 (has links)
Innerorts-Knotenpunkten gilt aufgrund der vielen Unfälle eine hohe Aufmerksamkeit in der Unfallforschung und -prävention. Die vorliegende Arbeit identifiziert und quantifiziert Einflüsse, welche die Komplexität von Knotenpunkten bestimmen und sich so auf Fehlerraten und somit Unfallzahlen auswirken. Dazu werden verallgemeinert lineare Modelle verwendet. Dabei erweisen sich neben der Verkehrsstärke vor allem die Anzahl der Konfliktpunkte an nichtsignalisierten Knotenpunkten sowie die Links- und Rechtsabbiegersignalisierungen an signalisierten Knotenpunkten als signifikante Einflüsse auf die Unfallzahlen. Entsprechend können komplexitätsverringernde Maßnahmen abgeleitet werden. / A great deal of research on road safety and accident prevention focuses on urban intersections due to high crash frequencies. In this paper urban intersection complexity is broken down into single quantifiable effects that determine crash counts using generalised linear models. Besides traffic volumes it can be shown that the number of conflict points explain crash counts at non-signalised intersections. Whereas crash counts at signalised intersections are effected by protected left- and right-turn signalling. Practical measures can be deduced from this work in order to manage intersection safety.

Modernizace ulice Brněnská v Miroslavi / Design of Brněnská street - MiroslavVeselý, Petr January 2022 (has links)
The subject of the diploma thesis is the elaboration of documentation for the issuance of a joint decision (DÚSP) for the project Modernization of Brněnská Street in Miroslav. The reason for the modernization is the emergency condition of the existing road and its unsatisfactory technical solution. The communication of functional group B (collection) is located in the urban area of the city. As part of the modernization of Brněnská Street, modifications of intersections, exits, sidewalks and parking spaces are also addressed.

GIS-based Episode Reconstruction Using GPS Data for Activity Analysis and Route Choice Modeling / GIS-based Episode Reconstruction Using GPS DataDalumpines, Ron 26 September 2014 (has links)
Most transportation problems arise from individual travel decisions. In response, transportation researchers had been studying individual travel behavior – a growing trend that requires activity data at individual level. Global positioning systems (GPS) and geographical information systems (GIS) have been used to capture and process individual activity data, from determining activity locations to mapping routes to these locations. Potential applications of GPS data seem limitless but our tools and methods to make these data usable lags behind. In response to this need, this dissertation presents a GIS-based toolkit to automatically extract activity episodes from GPS data and derive information related to these episodes from additional data (e.g., road network, land use).
The major emphasis of this dissertation is the development of a toolkit for extracting information associated with movements of individuals from GPS data. To be effective, the toolkit has been developed around three design principles: transferability, modularity, and scalability. Two substantive chapters focus on selected components of the toolkit (map-matching, mode detection); another for the entire toolkit. Final substantive chapter demonstrates the toolkit’s potential by comparing route choice models of work and shop trips using inputs generated by the toolkit.
There are several tools and methods that capitalize on GPS data, developed within different problem domains. This dissertation contributes to that repository of tools and methods by presenting a suite of tools that can extract all possible information that can be derived from GPS data. Unlike existing tools cited in the transportation literature, the toolkit has been designed to be complete (covers preprocessing up to extracting route attributes), and can work with GPS data alone or in combination with additional data. Moreover, this dissertation contributes to our understanding of route choice decisions for work and shop trips by looking into the combined effects of route attributes and individual characteristics. / Dissertation / Doctor of Philosophy (PhD)
