  1. 11. Analysis of Retroreflection and other Properties of Road Signs

    Författare :Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

    Sammanfattning : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.

  3. 12. Synthetic Aperture Radar Signal and Image Processing for Moving Target Indication and Side Lobe Suppression

    Författare :Thomas Sjögren; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; Space time adaptive processing;

    Sammanfattning : The thesis summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. LÄS MER

  4. 13. Advance Traffic Signal Control Systems with Emerging Technologies

    Författare :Junchen Jin; Xiaoliang Ma; Iisakki Kosonen; Henrik Pettersson; Ruey Long (Kelvin) Cheu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transportvetenskap; Transport Science;

    Sammanfattning : Nowadays, traffic congestion poses critical problems including the undermined mobility and sustainability efficiencies. Mitigating traffic congestions in urban areas is a crucial task for both research and in practice. LÄS MER

  5. 14. Decision-Making in Automotive Collision Avoidance Systems

    Författare :Mattias Brännström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; collision avoidance; active safety; threat assessment; driver modeling;

    Sammanfattning : This thesis is concerned with decision-making in systems that can detect hazardous traffic situations and assist drivers in avoiding collisions by using automatic braking or steering. The aim with these systems is to reduce the number of accidents and their consequences without disturbing the driver with unnecessary interventions during normal traffic conditions. LÄS MER

  7. 15. On Threat Assessment and Decision-Making for Avoiding Automotive Vehicle Collisions
