  2. 21. Geo-environmental considerations in transport infrastructure planning

    Author : Caroline Karlsson; Bo Olofsson; Ulla Mörtberg; Joanne Robison Fernlund; João Manuel Coutinho Rodrigues; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Roads; Railways; Geology; GIS; Decision support; Modelling; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Transport infrastructure constitutes one of the key factors to a country’s economic growth. Investment in new transport infrastructure might cause potential environmental impacts, and if a project has several alternative corridors open for suggestion then each alternative corridor will have a different impact on the environment.

  4. 22. Sustainability Transitions in Established Industries : The case of European Commercial Transport Vehicles

    Author : Behbood Borghei; Thomas Magnusson; Lars Coenen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sociotechnical transitions; Multilevel Perspective; System Innovations; Environmental Innovation; Systems of Innovation; Institutions; Environmental policy; Environmental regulation;

    Abstract : With the increasing trends in trade of goods and services as well as the expansion of road infrastructure and networks, commercial road transport has dominated a significant share of inland and urban logistics in the world and particularly in Europe. This includes not only the basic supply of citizens’ needs through long-haul traffic and short-distance city trucks but also by providing urban services such as courier delivery, household waste  pickup and refuse collection as well as passengers movements by public bus transport and inter-city coach transit.

  5. 23. LCC Applications for Bridges and Integration with BMS

    Author : Mohammed Safi; Håkan Sundquist; Raid Karoumi; Milan Veljkovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Management; life-Cycle Costing; LCC; Bridge Management System; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Bridges are vital links in many transport networks and represent a big capital investment for both governments and taxpayers. They have to be managed in a way that ensures society's needs are optimally met. In many countries, bridges are mainly managed using bridge management systems (BMSs). READ MORE

  6. 24. Justifying mega-projects : An analysis of the Swedish high-speed rail project

    Author : Erik Ronnle; Företagsekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transport policy; decision making; cost-benefit analysis; narrative; mega-projects;

    Abstract : Mega-projects are a growing phenomenon worldwide. More and more projects are started and they grow ever bigger in size. At the same time, there is overwhelming evidence that mega-projects tend to run late, overrun in terms of costs and fail to deliver the expected benefits. READ MORE

  7. 25. Quasi-analytical Modelling and Optimisation Techniques for Transport Aircraft Design

    Author : Askin T. Isikveren; KTH; []
    Keywords : aircraft; conceptual; design; specifications; atmosphere; geometry; weight; aerodyanmics; propulsion; operational performance; stability and control; constrained multi-objective optimisation; computer aided design; regional; business; high-transonic; ;

    Abstract : The research work presented here focuses on the subject oftransport aircraft design at the pre-design or conceptuallevel. The primary topics addressed are: (1) generation of avast array of new quasi-analytical expressions to permit aconceptual treatment of commercial and business transportaircraft with adequate sensitivity for more advanced tradestudies; (2) review and adoption of a method to predictstability and control characteristics (using the Mitchellmethod); (3) a study of the relative merits between variousmethods in facilitating an expedient and robust constrainedmulti-objective optimisation result within the context oftraditional conceptual design problems (Genetic Algorithms andNelder-Mead Simplex search); (4) creation of a software packageas a new and unique conceptual tool that permits the generationof design proposals in an accurate yet expeditious manner; and,(5) practical demonstration of the new conceptual designsoftware package by undertaking some actual aircraft designproposals.
