    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsvetenskaper; Social sciences; maximum likelihood; headways; critical gaps; driver behaviour; capacity; Gap acceptance; two-lane roundabouts; Technological sciences; Teknik;

    Abstract : Problem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. READ MORE

  4. 2. Mimic: A Microscopic Simulation Model for Rural Road Traffic

    Author : Stig O. Simonsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Safety margins in the driver

    Author : Rickard Nilsson; David Lee; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The primary aim of this thesis is to highlight the most important features of driving and to describe the models that have attempted to conceptualise these features. The discussion focuses on the concept of "safety margin." The concept is elaborated upon in an effort to enhance its usefulness as an empirical tool in traffic research. READ MORE
