  1. 16. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

    Författare :Azra Habibovic; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident prevention; Naturalistic observation; Causation analysis; Active safety system; Vulnerable road user VRU ; Driver behavior; Functional requirements; Statistical analysis; VRU behavior;

    Sammanfattning : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.

    Sammanfattning : This thesis consists of an introductory chapter and four research papers, summarized as follows. The overall purpose is to study various external effects of the transport system; effects that are not considered (or not fully considered) today. LÄS MER

  4. 18. Filtering and modelling for automotive safety systems

    Författare :Fredrik Sandblom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; automotive safety; sensor data fusion; motion models; radar sensor models; filtering theory; moment estimation;

    Sammanfattning : This thesis makes five important contributions to the development of an automotive safety system: filtering algorithms, three modelling frameworks concerning the usage of radar detections in tracking, vehicle motion, and decision-making for intervention decisions, and finally the implementation architecture.In the filtering context, we have developed a new sigma-point method for estimating the moments of a transformed Gaussian random variable.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architectural analysis; architectural program; property developer discourse; discourse analysis; aesthetic design program; municipality planning; architectural quality programs; planning process; road movie; city development; city environment program; traffic planning discourse analysis; instrument of evaluation; road architecture; Arkitekturdiskurs; arkitekturprogram; byggherrediskurs; diskursanalys; gestaltningsprogram; kommunal planering; kvalitetsstyrning; planeringsprocess; road movie; stadsutveckling; stadsmiljöprogram; trafikplaneringsdiskurs; utvärderingsinstrument; vägarkitektur; Architecture; Arkitektur;

    Sammanfattning : This licentiate thesis on architecture addresses how the state and municipalities use programs that deal with the design process in town planning projects. The author describes the process of creating an aesthetic design program and also studies a completed aesthetic design program. LÄS MER

  7. 20. Willingness to Pay for a Reduction in Road Mortality Risk: Evidence from Sweden

    Författare :Henrik Andersson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Willingness to Pay; Value of a Statistical Life; Revealed preferences; Stated preferences; economic systems; economic theory; econometrics; Economics; ekonomisk teori; ekonometri; ekonomisk politik; ekonomiska system; economic policy; Nationalekonomi; Road-mortality risk;

    Sammanfattning : The thesis consists of an introductory chapter, followed by three chapters in which willingness to pay (WTP) for a reduction in car- and road-mortality risk is estimated using both revealed- and stated-preference methods. In chapter 2 the hedonic regression technique is used to estimate the value of traffic safety, using information from the Swedish market for automobiles. LÄS MER
