  1. 1. Large-Eddy Simulation for Computing the Flow Around Vehicles

    Författare :Sinisa Krajnovic; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Subgrid scale model; Bus; SGS model; Car; Vehicle; Large eddy simulation;

    Sammanfattning : The feasibility of the use of large-eddy simulation (LES) in external vehicle aerodynamics is investigated. The computational requirement for LES of the full size car at road conditions is beyond the capability of computers in the near future. Since LES cannot be used for quantitative prediction of this flow, i.e. LÄS MER

  2. 2. Mimic: A Microscopic Simulation Model for Rural Road Traffic

    Författare :Stig O. Simonsson; Chalmers University of Technology; []
    Nyckelord :computer model; time headway; log normal distribution; Chi-Square test; gap-acceptance; rural road network; car-following; traffic simulation model; alignment; sight distance; Kolmogorov-Smirnoff test; software system; statistics;

    Sammanfattning : The purpose of this dissertation is to outline the theoretical basis of a road traffic simulation model, named Mimic, that constitutes the key elements of a system for estimating road user effects and environmental impacts. The simulation model suggested is a microscopic road traffic simulation model and it is structured to be used for networks of rural roads. LÄS MER

  3. 3. Simulation of Surrounding Vehicles in Driving Simulators

    Författare :Johan Olstam; Jan Lundgren; Jonas Jansson; Mikael Adlers; Pontus Matstoms; Martin Fellendorf; Statens väg- och transportforskningsinstitut; []
    Nyckelord :Traffic; Micro; Simulation; Mode; Overtaking; Lane changing; Car following; Rural road; Mathematical model; Simulator; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Driving simulators and microscopic traffic simulation are important tools for making evaluations of driving and traffic. A driving simulator is de-signed to imitate real driving and is used to conduct experiments on driver behavior. Traffic simulation is commonly used to evaluate the quality of service of different infrastructure designs. LÄS MER

    Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER

  5. 5. Pro-environmental travel behavior : The importance of attitudinal factors, habits, and transport policy measures

    Författare :Louise Eriksson; Jörgen Garvill; Annika Nordlund; Linda Steg; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; value-belief-norm theory; car habit; policy specific beliefs; car use reduction; acceptability; behavioral adaptations; travel demand management measures; transport policy measures; Psychology; Psykologi;

    Sammanfattning : The aim of this thesis was to study determinants of a readiness for pro-environmental travel behavior in households. Four empirical studies were conducted examining reduction in car use (Study I), acceptability of transport policy measures (Study II and III), and behavioral adaptations in response to travel demand management (TDM) measures (Study IV).
