  2. 1. Evaluation of bus priority strategiesin coordinated traffic signal systems

    Author : Johan Wahlstedt; Karl-Lennart Bång; Haris Koutsopoulos; Lars-Göran Mattsson; Kosonen Iisakki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bus priority; public transport priority; transit priority; PTSP; TSP; traffic signal; traffic signal control; traffic signal control systems; self-optimising signal control; PRIBUSS; SIL simulation; traffic simulation; Transportvetenskap; Transport Science;

    Abstract : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. READ MORE

  4. 2. Impacts of Traffic Signal Control Strategies

    Author : Azhar Al-Mudhaffar; Karl-Lennart Bång; Nagui M. Rouphail; KTH; []
    Keywords : Driver behavior; Dilemma zone; Incident reduction; Signal control; Lhovra; Spot; Pribuss; Bus priority; Field measurement; Simulation; Calibration; Traffic performance; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Traffic signals are very cost effective tools for urban traffic management in urban areas. The number of intersections in Sweden controlled by traffic signals has increased since the seventies, but efforts to study the traffic performance of the employed strategies are still lacking.

  5. 3. On Spectrum Sensing for Secondary Operation in Licensed Spectrum : Blind Sensing, Sensing Optimization and Traffic Modeling

    Author : Mohamed Hamid; Ben Slimane Slimane; Niclas Björsell; Octavia Dobre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Spectrum Sensing; Sensing Optimization; Blind Sensing; Traffic Modelling; Energy detection; Maximumum-minimum Eigenvalue Detection; Discriminant anlysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. READ MORE

  6. 4. Interdomain Traffic Engineering and Faster Restoration in Optical Networks

    Author : Americo Francisco Muchanga; Björn Pehrson; Lena Wosinska; Fredrik Orava; Mouftah Hussein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interdomain Routing; Network Recovery; Restoration in Optical Networks; Optics; Optik;

    Abstract : Internet traffic has surpassed voice traffic and is dominating in transmission networks. The Internet Protocol (IP) is now being used to encapsulate various kinds of services. The new services have different requirements than the initial type of traffic that was carried by the Internet network and IP. READ MORE

  7. 5. AURALIZATION, PERCEPTION AND DETECTION OF TYRE–ROAD NOISE

    Author : Alice Hoffmann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perception; Psychoacoustics; Rolling Noise; Traffic Detection; Reaction Time; Auralization; Tyre Road Noise;

    Abstract : Due to improvements in combustion engines and electric engines for cars, tyre noise has become the prominent noise source at low and medium speeds. Models exist that simulate the noise produced by a rolling tyre, as do models that auralize specific traffic situations from a basic data set. READ MORE
