  1. 1. Traffic Emissions of Aerosols

    Författare :Matthias Vogt; Douglas Nilsson; Eiko Nemitz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. LÄS MER

  2. 2. Safety within the Vessel Traffic Service (VTS) Domain. Understanding the role of the VTS for safety within maritime traffic management

    Författare :Gesa Praetorius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; maritime safety; safety construction; traffic management; Vessel Traffic Service VTS ;

    Sammanfattning : Vessel Traffic Service (VTS) is a shore-sided service implemented to promote the safety of navigation, safety of life at sea, and the protection of the marine environment. Its purpose is to work for safe and fluent traffic movements within a determined area, a VTS area. LÄS MER

  3. 3. Light Design : Outdoor Urban Public Places : - Urban Lighting: Design and Technologies -

    Författare :José Nuno Sampaio; Björn-Erik Erlandsson; Izael Pereira Da Silva; KTH; []
    Nyckelord :Light-based Technologies and Design; Energy Technology; Energiteknik;

    Sammanfattning : Most of the present time outdoor lighting investments seem to be focused on road and automotive traffic facilities or oriented toward safety, security and efficiency. We can identify this in many of the world cities, as a globally spread common practice, where lighting is still highly perceived as a pure matter of quantities’ distribution.

  4. 4. Evaluation of Road Equipment with Emphasis on Condition Assessment

    Författare :Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. LÄS MER

  5. 5. Exploring Road Traffic Interactions Between Highly Automated Vehicles and Vulnerable Road Users

    Författare :Victor Fabricius; Pontus Wärnestål; Jonas Andersson; Barry Brown; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automated driving system; Vulnerable road user; Traffic interaction; User Experience;

    Sammanfattning : Understandings of road traffic interactions are largely based on human-human interactions. However, the development of vehicles controlled by highly auto- mated driving systems (ADS) would introduce a radically novel type of road user. LÄS MER
