  1. 21. Markov Decision Problems in ATM Traffic Control

    Författare :Ernst Nordström; Lars Asplund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Sammanfattning : This thesis discusses how to make cost-effective use of the communication resources in the Broadband Integrated Services Digital Network (B-ISDN), which is based on the Asynchronous Transfer Mode (ATM) switching and multiplexing technique.The thesis deals with two important functions in ATM traffic control, namely Call Admission Control (CAC) and routing, which affects both the network operator's revenue over time and the users' Quality of Service (QOS) and Grade of Service (GOS).

  3. 22. Public road safety policy change and its implementation : Vision zero a road safety policy innovation

    Författare :Matts-Åke Belin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vision Zero;

    Sammanfattning : It has been estimated that, worldwide, the number of people killed in road traffic crashes each year is almost 1.2 million, while the number of injured could be as high as 50 million. LÄS MER

  4. 23. Emission estimation based on traffic models and measurements

    Författare :Nikolaos Tsanakas; Jan T. Lundgren; Joakim Ekström; Johan Olstam; Marcus Gerstenberger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Traffic congestion increases travel times, but also results in higher energy usage and vehicular emissions. To evaluate the impact of traffic emissions on environment and human health, the accurate estimation of their rates and location is required. LÄS MER

  5. 24. 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).

  7. 25. Dynamic Traffic Control in Multiservice Networks - Applications of Decision Models

    Författare :Ulf Ahlfors; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed-Memory Systems; Overload Control; Call Admission Control; Routing; Optimization; Multiservice Networks; Markov Decision Process; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. LÄS MER
