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. On the road to climate neutral Swedish transportation: Energy system modelling to support the transition at national, regional, and local levels

   Author : Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Hannah E. Daly; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy transition; Energy system modelling; TIMES-City; TIMES-Sweden; Transportation; Decarbonisation; Climate mitigation; Energiteknik; Energy Engineering;

   Abstract : Transportation is a critical pillar of modern society. Over the past decades, growth in mobility of people and goods have been both enabled by and dependent upon fossil fuels. Strong action is needed to break this dependence in order to reduce CO2. READ MORE

5. 3. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses

   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

6. 4. Bayesian Models for Spatiotemporal Data from Transportation Networks

   Author : Héctor Rodriguez Déniz; Mattias Villani; Augusto Voltes-Dorta; Yusak Susilo; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; Transportation networks; Spatiotemporal data; Machine learning; Bayesiansk statistik; Transportnätverk; Spatiotemporal data; Maskininlärning;

   Abstract : Urbanization has caused a historical transformation at a global scale, and humanity is moving towards a fully connected society where cities will concentrate population, infrastructure and economic activity. A key element in the cities’ infrastructure is the transportation system, as it facilitates the mobility of people and goods. READ MORE
