  1. 1. Crash Compatibility between Roadside Infrastructure and Passenger Vehicles: Improving the Geometric and Structural Compatibility to Reduce Fatalities

    Författare :Weijia Wu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crash simulations.; ditches; accident analysis; crash compatibility; guardrails; roadside safety;

    Sammanfattning : Roadside accidents cause a significant number of fatalities each year in the world. To reducethis type of accident, roadside infrastructure needs to be investigated to improve protection todifferent kinds of passenger vehicles during crashes. LÄS MER

  3. 2. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

    Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER

  4. 3. Integration of car and road infrastructure design : crash severity and occupant injury risk evaluations in frontal real-world crashes

    Författare :Anders Ydenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During the last decade, traffic safety has not only been a matter of vehicle crashworthiness but an increasing interest can also be observed in the integration between vehicle and road infrastructure design. Research projects with a focus on merging these areas are however in their infancy. LÄS MER

  5. 4. Automotive Sensor Fusion for Situation Awareness

    Författare :Christian Lundquist; Fredrik Gustafsson; Thomas Schön; Jonas Sjöberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik;

    Sammanfattning : The use of radar and camera for situation awareness is gaining popularity in automotivesafety applications. In this thesis situation awareness consists of accurate estimates of theego vehicle’s motion, the position of the other vehicles and the road geometry. LÄS MER
