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

    Author : Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Keywords : Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    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

  4. 2. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation

    Author : Ellen Grumert; Jan Lundgren; Andreas Tapani; Wilco Burghout; Statens väg- och transportforskningsinstitut; []
    Keywords : Variable speed limit; Traffic; Micro; Simulation; Data exchange; Telecommunication; Vehicle; Transport infrastructure; Intelligent transport system; In vehicle information; 23 Road: ITS och traffic; 23 Road: ITS och traffic; 25 Road: Traffic theory; 25 Road: Traffic theory;

    Abstract : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. READ MORE

  5. 3. Developments in the theory of the Prigogine-Herman kinetic equation of vehicular traffic

    Author : Alexandros Sopasakis; Partiella differentialekvationer; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chapman-Enskog expansion; Traffic; Prigogine-Herman; Kinetic equation; Unstable flow;

    Abstract : The nonlinear kinetic equation of Prigogine and Herman is examined in regards to existence and uniqueness of solutions. The solution exists and is unique in the Banach space of bounded continuous functions over a particular subspace Ω. READ MORE

  6. 4. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Author : Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. READ MORE

  7. 5. Valuation and pricing of traffic safety

    Author : Gunnar Lindberg; Lars Hultkrantz; Olof Johansson-Stenman; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value of statistical life; Marginal cost pricing; External cost; Risk elasticity; Pricing policies; Traffic accidents; Railway accidents; Heavy goods vehicle accidents; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Abstract : This thesis consists of six essays covering the topic of valuation and pricing of accidents. In the first essay a theory of the external marginal cost of accidents is presented. The external cost is dependent on the value of statistical life, the proportion internal cost and the so called risk elasticity, i.e. READ MORE
