  1. 1. Occupant casualties in bus and coach traffic injury and crash mechanisms

    Detta är en avhandling från Umeå : Kirurgisk och perioperativ vetenskap

    Författare :Pontus Albertsson; Ulf Björnstig; Torbjörn Falkmer; Claes Tingvall; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; bus; coach; aerodynamics; crash; non-crash; cross-wind; injuries; weight distribution; road friction; restraints; haddons matrix; prevention; severe crash; mass casualty; major incident; alighting; boarding; incidents; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; Surgery; kirurgi;

    Sammanfattning : Background: The relevance of conducting this thesis is evident by the fact that bus and coach casualties have been “stubbornly stable” in Europe recent years and a need for investigating if a similar trend could be found in Sweden is therefore obvious. It was also important to add new knowledge to the bus and coach research in Sweden, since many areas were scarcely addressed. LÄS MER

  2. 2. Surviving a major bus crash experiences from the crash and five years after

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Isabelle Doohan; Britt-Inger Saveman; Ulf Björnstig; Per-Olof Michel; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bus crash; major road traffic crash; survivors; injuries; consequences; experiences; recovery; social support; emergency care; compassionate care; long-term recovery;

    Sammanfattning : Background Major road traffic crashes (RTCs) can have a significant impact on the survivors, their family, and their friends, as well as on emergency personnel, volunteers, and others involved. However, survivors’ perspectives are rare or missing in research on major RTCs in Sweden. LÄS MER

  3. 3. Towards electrified public bus transport The case of Stockholm

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Maria Xylia; Semida Silveira; Maria Börjesson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric bus; charging infrastructure; optimisation; public transport; fossil-free; transport planning; Sweden; Energiteknik; Energy Technology;

    Sammanfattning : This thesis addresses the challenge of road transport electrification using a systems approach for the particular context of Stockholm’s public transport system. The objective is to identify the benefits of large-scale bus electrification on energy efficiency and greenhouse gas emissions, as well as the cost and planning considerations required for achieving such a shift.
