  2. 1. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels

    Author : Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Krister Sandberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system analysis; ESOM; Transportation; Climate change; Air quality; Energy Engineering; Energiteknik;

    Abstract : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. READ MORE

  4. 2. Transportation asset management : Quality related accounting, measurements and use in road management processes

    Author : Berth Jonsson; Hans Lind; Lars Westin; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : Today there are shortcomings in monitoring, control, analyses, learning and reporting of the results of activities and operations in the road management processes. There are also shortcomings in transparency and verifiability, in knowledge of road management’s costs and life cycle costs, of the road capital’s standard and condition and in measures of quality deficiency costs, productivity and maintenance backlog.

  5. 3. Valuation of goods transportation characteristics : A study of a sparsely populated area

    Author : Kerstin Westin; Einar Holm; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Just-In-Time; Goods transportation; Sparsely populated areas; Social and Economic Geography; kulturgeografi;

    Abstract : This study describes how consumers and providers of transportation services in a sparsely populated area valuate different transportation characteristics and estimates how these valuations might affect the total goods flows and the flows on individual Origin-Destination links. It also tests Stated-Preference methods as a tool for valuating transportation characteristics. READ MORE

    Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  7. 5. Cost-effective fuel and technology choices in the transportation sector in a future carbon constrained world: Results from the Global Energy Transition (GET) model

    Author : Maria Grahn; Chalmers tekniska högskola; []
