  1. 16. Hybrid microscopic-mesoscopic traffic simulation

    Författare :Wilco Burghout; Karl-Lennart Bång; Jaime Barceló; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorsystem; Datorsystem; Computer engineering; Datorteknik;

    Sammanfattning : Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of complicated traffic facilities and Intelligent Transportation Systems that often consist of complex traffic management, safety and information systems.

  3. 17. Microscopic Simulation of Pedestrian Traffic

    Författare :Fredrik Johansson; Jan Lundgren; Andreas Tapani; Anders Peterson; Anders Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : There has recently been a renewed interest in planning for pedestrian traffic, primarily in connection to public transport interchange stations, since these are important for public transport to constitute an attractive alternative to car usage. This thesis concerns microscopic simulation of pedestrian traffic, which is a promising tool for analyzing and predicting the traffic situation in a given pedestrian facility; particularly powerful when the traffic is congested.

  4. 18. A Simulation-Based Safety Analysis of CACC-Enabled Highway Platooning

    Författare :Maytheewat Aramrattana; Tony Larsson; Cristofer Englund; Jonas Jansson; Vicente Milanés; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; driving simulator; traffic simulator; network simulator; C-ITS; cooperative intelligent transport systems; platooning;

    Sammanfattning : Cooperative Intelligent Transport Systems (C-ITS) enable actors in the transport systems to interact and collaborate by exchanging information via wireless communication networks. There are several challenges to overcome before they can be implemented and deployed on public roads. LÄS MER

  5. 19. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

    Författare :Lars Ekman; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

    Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER

  7. 20. Mimic: A Microscopic Simulation Model for Rural Road Traffic

    Författare :Stig O. Simonsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer model; time headway; log normal distribution; Chi-Square test; gap-acceptance; rural road network; car-following; traffic simulation model; alignment; sight distance; Kolmogorov-Smirnoff test; software system; statistics;

    Sammanfattning : The purpose of this dissertation is to outline the theoretical basis of a road traffic simulation model, named Mimic, that constitutes the key elements of a system for estimating road user effects and environmental impacts. The simulation model suggested is a microscopic road traffic simulation model and it is structured to be used for networks of rural roads. LÄS MER
