1. 1. Noise emissions from sustainable transport : A multi-scale modeling approach

   Författare :Johan Nygren; Susann Boij; Romain Rumpler; Ciarán J. O'Reilly; Eoin King; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic simulation; sustainable transport; environmental noise; vehicle acoustics; energy efficiency; Trafiksimulering; hållbar transport; samhällsbuller; fordonsakustik; energieffektivitet; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).

4. 3. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

   Författare :Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

   Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER
