  1. 1. Dynamic speed adaptation based on information technology - a theoretical background

    Författare :Andras Varhelyi; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; driver acceptance; appropriate speeds; speed behaviour; critical conditions; Social sciences; Samhällsvetenskaper;

    Sammanfattning : Knowledge on the factors influencing driver speed-behaviour, the relationship between speed and traffic safety and means to influence speed behaviour is systematised. Expert judgements and the high proportion of injury accidents show that improved speed adaptation has the largest safety potential in the following situations: - Road surface-, visibility and weather affected situations (e.
