  1. 1. Influence Of Road Feature Variables On Accident Rate

    Författare :Sarbaz Najib Othman; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safe road geometry; accident rate; black spots; accident causation; Traffic safety;

    Sammanfattning : The main objective of this traffic safety investigation was to find critical road parameters affecting accident rate (AR). The secondary objective was to analyze any identified risk factors from a vehicle dynamics perspective. LÄS MER

  2. 2. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

    Detta är en avhandling från Department of Traffic Planning and Engineering, Lund Institute of Technology

    Författare :Lars Ekman; Lund University.; Lunds universitet.; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

    Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER

  3. 3. Traffic Safety Dimensions and the Power Model to Describe the Effect of Speed on Safety

    Detta är en avhandling från Traffic Engineering

    Författare :Göran Nilsson; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk; consequence; dimension; accident rate; injury rqte; speed; speed limit; cross-sectionel; Road transport technology; Safety technology; Vägtransportteknik; Säkerhetsteknik; accidents; Traffic safety; exposure;

    Sammanfattning : Traffic safety work needs different methods and tools in order to choose and evsaluate traffic safety measures. The thesis contributes to this problem by presenting and visualizing a method which describes the traffic safety situation in several dimensions. LÄS MER

  4. 4. Post Impact Vehicle Path Control in Multiple Event Accidents

    Detta är en avhandling från Traffic Engineering

    Författare :Derong Yang; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post Impact; Optimal Path Control.; Vehicle Dynamics; Multiple-Event Accidents; Collision Avoidance; Accident Analysis;

    Sammanfattning : Recent statistics show that multiple-event accidents (MEAs) possess an increasing fraction of all vehicle traffic accidents. They are characterized by having at least one vehicle subjected to more than one harmful event, such as collision with another vehicle. MEAs now comprise approximately 25% of all passenger vehicle accidents. LÄS MER

  5. 5. Studies on the Gamma Radiation Environment in Sweden with Special Reference to 137Cs

    Detta är en avhandling från Göteborg

    Författare :Sara Almgren; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gamma radiation; caesium; 137Cs; deposition; migration; precipitation; in situ; CDE; NWF; Chernobyl; soil sampling; field measurements; dose measurements; dose rate; TLD; natural radiation; Kriging;

    Sammanfattning : Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case of fallout from nuclear weapons (NWF) or accidents, knowledge and monitoring of external gamma radiation and radionuclide concentrations in the environment is important.
