  1. 1. Sustainable Personal Road Transport : The Role of Electric Vehicles

    Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

    Sammanfattning : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. LÄS MER

  3. 2. Distributed Road Grade Estimation for Heavy Duty Vehicles

    Författare :Per Sahlholm; Karl Henrik Johansson; Emilio Frazzoli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; estimation; distributed systems; automatic control; heavy duty vehicles; road grade; road maps; Automatic control; Reglerteknik;

    Sammanfattning : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. LÄS MER

  4. 3. Road Safety Development Index : Theory, Philosophy and Practice

    Författare :Ghazwan Al-Haji; Kenneth Asp; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport; Road Traffic; Sustainability; Road safety; European research cooperation; Civil engineering and architecture; Research on Europe; Public health science; Statistics; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. LÄS MER

  5. 4. Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective

    Författare :Lina Nordin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Road climate; RWIS; frost; snow; fuel consumption; heavy-duty vehicles; route optimisation programme; energy efficiency; winter road maintenance;

    Sammanfattning : Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency potentials in the different aspects of the road maintenance area. LÄS MER

  7. 5. Operating cycle representations for road vehicles

    Författare :Pär Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Sammanfattning : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. LÄS MER
