    Sammanfattning : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. LÄS MER

    Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER

  4. 3. Soft measures to shift modality

    Författare :Alfred Söderberg; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soft transport measures; Modal shift; Innovation; ICT; E-bikes; Segmentation; Motivation; Evaluation;

    Sammanfattning : Traffic accumulated by cars is responsible for considerable problems in our cities. The problem is partly about the negative effects on human health due to harmful particulate emissions, noise, traffic accidents and sedentary lifestyles, partly about the space it occupies, which leads to congestion, and the fact that valuable land is taken up by road infrastructure and parking lots.

  5. 4. Optimization of Snow Removal in Cities

    Författare :Roghayeh Hajizadeh; Kaj Holmberg; Elina Rönnberg; Henrik Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Removing snow in a city is an unavoidable task in Nordic countries like Sweden. A number of streets in an area need to be cleared of snow by a limited number of vehicles and the tours for the vehicles must be planned in order to minimize the time and/or cost. LÄS MER

  7. 5. On urbanisation and birds : Insights from a molecular and physiological perspective

    Författare :Pablo Salmon; Evolutionär ekologi; []
    Nyckelord :Air Pollution; Antioxidants; Birds; great tit Parus major; Local adaptation; Nitrogen oxides; Oxidative stress; Parallel evolution; Survival; Telomere dynamics; Telomeres; Urbanisation;

    Sammanfattning : Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. LÄS MER
