  1. 1. Loyal Speed Adaptation Speed limitation by means of an active accelerator and its possible impacts in built-up areas

    Författare :Sverker Almqvist; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active accelerator; LSA; speed; speed reduction; driver behaviour; traffic safety; ISA; Teknik; Technological sciences; Road transport technology; Vägtransportteknik;

    Sammanfattning : Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, which have been found to be an important factor for causing serious and fatal accidents.

  2. 2. On Auxiliary Systems in Commercial Vehicles

    Författare :Christian Andersson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; simalation model; auxiliary system; vehicle; hybrid driveline; Road transport technology; Vägtransportteknik; pollution control; Environmental technology; kontroll av utsläpp; Energy research; Energiforskning;

    Sammanfattning : As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. LÄS MER

  3. 3. Consequences of Traffic Casualties in Relation to Traffic-Engineering Factors - An Analysis in Short-term and Long-term Perspectives

    Författare :Monica Berntman; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Police and Hospital Data; Traffic Casualties; Consequences for Society and Individulas; in Short-term and Long-term Perspectives; Health Index; Traffic-Engineering Factors; ISS; Potential Traffic Safety Measures; Predictors; Road transport technology; Vägtransportteknik;

    Sammanfattning : The over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. LÄS MER

  4. 4. Catching the Bus in Old Age - Methodological Aspects of Accessibility Assessments in Public Transport

    Författare :Gunilla Carlsson; Arbetsterapi och aktivitetsvetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rehabilitering medicinsk och social ; revalidation; rehabilitation; kinesitherapy; cluster analysis; activity; functional limitation; crticial incident; Enabler; environment; elderly; focus group; model; occupational therapy; participant observation; planning; performance; travel; Physical medicine; Road transport technology; Vägtransportteknik;

    Sammanfattning : Engagement in daily activities is central for people’s health and well-being. Today, our activity arenas mostly cover great geographical areas, and to reach different activities we must travel. However, people with functional limitations are sometimes restricted in their travelling. LÄS MER

  5. 5. Are Beautiful traffic environments safer than Ugly traffic environments?

    Författare :Helena Drottenborg; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driving behaviour; traffic safety; eye blink; heart rate; mood; basic emotional process; environmental psychology; gestalt theory; ugly; aesthetics; beautiful; speed.; Road transport technology; Vägtransportteknik;

    Sammanfattning : To link aesthetics to traffic safety, the field of environmental psychology was consid-ered. A new model of driving behaviour was developed, based on Lewin’s (1951) equation, B = f (P,E) and by employing Küllers’ (1991) model of the basic emotional process. LÄS MER
