  1. 1. 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

  5. 5. 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
