  1. 1. Speed Choice : The Driver, the Road and Speed Limits

    Författare :Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Speed choice is one of the more characteristic features of driver behaviour. The speed a driver chooses to travel at determines the degree of difficulty he or she operates under. Higher speeds lead to more accidents, higher accident risk and more severe consequences of an accident. LÄS MER

  3. 2. Measurement systems and process orientation with focus on the order process

    Författare :Anders Ljungberg; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process measurement; measurement systems; process management; measurement; Technological sciences; Teknik;

    Sammanfattning : The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. LÄS MER

  4. 3. Speed characteristics of urban streets based on driver behaviour studies and simulation

    Författare :Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
    Nyckelord :Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. LÄS MER

  5. 4. Embedded Measurement Systems

    Författare :Lars Bengtsson; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

    Sammanfattning : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. LÄS MER

  7. 5. Bilars hastighet längs gator med gupp: metod för framställning av hastighetsprofiler och analys av hastighetsförlopp

    Författare :Joachim Karlgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road hump; speed reducing effect; traffic calming; speed measurement; speed profile;

    Sammanfattning : There is a well-documented relationship between motorists speed and the number, respectively severity, of accidents in urban streets. Also, studies have shown that vehicle emissions can increase on streets where speed reducing measures are installed, if the driving pattern of the motorists becomes more jerky. LÄS MER
