    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

  4. 2. Delays and Timetabling for Passenger Trains

    Author : Carl-William Palmqvist; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail; delay; timetable; train; punctuality; Rail transportation;

    Abstract : Travel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. READ MORE

  5. 3. Public Transportation in a Systems Perspective A Conceptual Model and an Analytical Framework for Design and Evaluation

    Author : Stig Franzén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control theory; systems design; cybernetics; passenger transport; urban transport; systems perspective; conceptual model; systems engineering; human-machine system; public transportation;

    Abstract : Today urban areas are faced with problems like traffic congestion, air pollution, and limited accessibility and transport policy issues are focused on the "sustainable city of the future". For decision-makers the crucial question is how, with limited financial resources, a system for public transportation should be designed and developed to provide attractive travel and transport services.
