  1. 21. 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

  3. 22. Safety of Cooperative Automated Driving : Analysis and Optimization

    Författare :Galina Sidorenko; Alexey Vinel; Johan Thunberg; Elisabeth Uhlemann; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; Cooperative Intelligent Transportation System C-ITS ; Vehicle-to-Vehicle V2V communication; emergency braking; road safety; ITS-G5; IEEE 802.11p; automated driving;

    Sammanfattning : New cooperative intelligent transportation system (C-ITS) applications become enabled thanks to advances in communication technologies between vehicles(V2V) and with the infrastructure (V2I). Communicating vehicles share information with each other and cooperate, which results in improved safety, fuel economy, and traffic efficiency. LÄS MER

    Sammanfattning : Advances in technologies for vehicular communication enable new applications for Cooperative Intelligent Transportation Systems (C-ITS). Communicating vehicles share information and cooperate, which allows for improved safety, fuel economy, and traffic efficiency. LÄS MER

  5. 24. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

    Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

  7. 25. Effects of hearing loss on traffic safety and mobility

    Författare :Birgitta Thorslund; Björn Lyxell; Björn Peters; Björn Lidestam; Håkan Alm; Statens väg- och transportforskningsinstitut; []
