2. 1. DEM Modelling of Unbound Granular Materials for Transport Infrastructures : On soil fabric and rockfill embankments

   Author : Ricardo de Frias Lopez; Johan Silfwerbrand; Leena Korkiala-Tanttu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete element method; granular materials; particle-scale behaviour; particle degradation; permanent deformation; resilient modulus; rockfill embankment; soil fabric; Diskreta elementmetoden; grusmaterial; verkningssätt på partikelnivå; nedbrytning; permanent deformation; styvhet; stenfylld bank; skelettstruktur; Transport Infrastructure; Transportinfrastruktur;

   Abstract : Unbound granular materials (UGM) are widely used as load-bearing layers and for embankment construction within transport infrastructures. These play a significant role on operation and maintenance of transportation systems. However, pavement and railway engineering still today rely heavily on empirical models based on macroscopic observations. READ MORE

4. 2. An Ontology-Based Platform for Information Integration : Supporting Sustainable Smart Transportation Infrastructure

   Author : Wiebke Belitz-Hellwich; Nicole Kringos; Annika Gram; Romain Balieu; Vangelis Angelakis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ontology; Semantic Web; Interoperability; Information Integration; Logistics; Simulation; Smart Port; ontologi; semantisk webb; interoperabilitet; informationsintegration; logistik; simulering; smart hamn.; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Abstract : Transportation and transportation infrastructure are major contributors to global emissions. Even though most of these emissions can be attributed to fuel consumption of vehicles, some of it is due to pavement construction and maintenance. READ MORE

5. 3. Life cycle assessment of transport systems and transport infrastructure : Investigating methodological approaches and quantifying impacts at project and network levels

   Author : Carolina Liljenström; Anna Björklund; Susanna Toller; Rolf André Bohne; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strategier för hållbar utveckling; Strategies for sustainable development;

   Abstract : Reducing greenhouse gas emissions from the transport sector is a key challenge to reach global climate targets and limit global warming to below 2 ºC. The use of life cycle assessment (LCA) may provide knowledge about the environmental impacts of transport systems so that emission reduction measures can be identified. READ MORE

6. 4. New perspectives on Strategic Choice of Measures in Swedish Transport Planning

   Author : Sofia Eckersten; Berit Balfors; Ulrika Gunnarsson-Östling; Fredrik Pettersson-Löfstedt; KTH; []
   Keywords : Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : Rapid changes in the global climate and declining biodiversity pronounces the need for adapting the transport system and transport infrastructure, which influence several sustainability issues and cause direct environmental impact through their use of land, as well as indirect impacts, for example, emissions of pollutants to air and water. The Swedish Transport Administration (STA) is responsible for and conducts a large part of the transport planning in Sweden and the STA endeavor to increase collaboration with other societal actors in transport planning.

7. 5. Simulation based evaluation of flexible transit

   Author : David Leffler; Erik Jenelius; Wilco Burghout; Oded Cats; Jan Persson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Abstract : Transport authorities are faced with the challenge of making effective use of existing transportation infrastructure under increasing needs of transport accessibility, sustainability, and safety. The ongoing growth and adoption of shared mobility options, the anticipation of automated vehicles, and the increased availability of real-time data brought on with the developments of Intelligent Transport Systems, have all inspired many innovations in public transit design.
