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

    Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Traffic Simulation; Rural Highway; Level-of-Serivice; Road safety; safety indicators; Advanced Driver Assistance Systems ADAS ; Other technology; Övriga teknikvetenskaper;

    Sammanfattning : 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. 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

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

    Författare :Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Nyckelord :Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; Technology; Traffic Simulation; Driving Simulator; Traffic Generation; Microscopic; Traffic models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : 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. LÄS MER

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

    Författare :Ghazwan Al-Haji; Kenneth Asp; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Författare :Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Sammanfattning : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. LÄS MER
