  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;

    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

  3. 2. 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;

    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

  4. 3. Shared e-scooter usage patterns : Analysis of app and trip data

    Författare :Boel Berg Wincent; Erik Jenelius; Wilco Burghout; Johan Olstam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; e-scooter; micromobility; elsparkcyklar; mikromobilitet; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

    Sammanfattning : There is an urgent need to shift the urban mode distribution towards public transportation, micromobility, and shared mobility as a critical step towards achieving sustainable cities. Micromobility, with shared e-scooters as the main driving force, has sprung up as a promising mode for cities since the late 2010s. LÄS MER

  5. 4. Simulation Based Evaluation of Advanced Driver Assistance Systems

    Författare :Roya Elyasi-Pour; Jan Lundgren; Johan Olstam; Ingmar Andreásson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Road transportation is an essential element of mobility in most countries and we can observe an increasing demand for both goods and passenger traffic. There are however important societal and economical problems related to road transportation in terms of congestions, traffic safety and environmental effects. LÄS MER

  7. 5. Towards microscopic models for bicycle traffic simulation

    Författare :Guillermo Pérez Castro; Johan Olstam; Fredrik Johansson; Heather Kaths; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As bicycling becomes an integral part of sustainable mobility, it becomes essential to enhance planning strategies that ensure bicycling as an efficient mode of transport. While traffic simulation has been extensively utilized for traffic planning of various modes of transport, this type of modeling support is largely lacking in the planning of bicycle traffic. LÄS MER
