  1. 1. Road Safety Development Index : Theory, Philosophy and Practice

    Författare :Ghazwan Al-Haji; Kenneth Asp; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport; Road Traffic; Sustainability; Road safety; European research cooperation; Civil engineering and architecture; Research on Europe; Public health science; Statistics; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. LÄS MER

  3. 2. Impacts of Traffic Signal Control Strategies

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

    Sammanfattning : 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.

  4. 3. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

    Författare :Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
    Nyckelord :Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.

  5. 4. Speed characteristics of urban streets based on driver behaviour studies and simulation

    Författare :Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
    Nyckelord :Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. LÄS MER

  7. 5. Hybrid microscopic-mesoscopic traffic simulation

    Författare :Wilco Burghout; Karl-Lennart Bång; Jaime Barceló; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorsystem; Datorsystem; Computer engineering; Datorteknik;

    Sammanfattning : Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of complicated traffic facilities and Intelligent Transportation Systems that often consist of complex traffic management, safety and information systems.
