  1. 1. A model for simulation and generation of surrounding vehicles in driving simulators

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Johan Olstam; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road: Traffic theory; Road: Traffic theory; Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; TECHNOLOGY; TEKNIKVETENSKAP; Technology; Traffic Simulation; Driving Simulator; Traffic Generation; Microscopic; Traffic models; TEKNIKVETENSKAP;

    Abstract : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. READ MORE

    Abstract : 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. READ MORE

  3. 3. Road traffic metals sources and emissions

    University dissertation from Kalmar

    Author : David Hjortenkrans; Högskolan i Kalmar.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Miljökemi; Environmental Chemistry;

    Abstract : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. READ MORE

  4. 4. A Traffic Simulation Modeling Framework for Rural Highways

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Andreas Tapani; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road: Traffic theory; Road: Traffic theory; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; TECHNOLOGY Other technology; TEKNIKVETENSKAP Övriga teknikvetenskaper; Traffic Simulation; Rural Highway; Level-of-Serivice; Road safety; safety indicators; Advanced Driver Assistance Systems ADAS ;

    Abstract : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. READ MORE

  5. 5. Traffic Emissions of Aerosols

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Matthias Vogt; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. READ MORE
