  2. 1. Modelling of Traffic Performance for Swedish Roads and Motorways

    Author : Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

    Abstract : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. READ MORE

  4. 2. Evaluation of Variable Speed Limits : Empirical Evidence and Simulation Analysis of Stockholm’s Motorway Control System

    Author : Albania Nissan; Haris N. Koutsopoulos; Tomer Toledo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorway Control System; Mainline Control; Variable Speed Limits; Driver Behavior; Capacity; Intelligent Transport Systems; microsimulation model; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Mechanical energy engineering; Mekanisk energiteknik; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. READ MORE

  5. 3. Visual demand in manual task performance - Towards a virtual evaluation

    Author : Tania Dukic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; working posture; computer manikin software; motion; visual demand;

    Abstract : Visual information is crucial for carrying out motor activities. However, knowledgeabout the effects of visual demand on the performance of manual tasks is not welldocumented. Visual determinants must be identified in order to be used in visualisationand simulation tools (e.g. READ MORE

  6. 4. Using Connected Vehicles in Variable Speed Limit Systems: : System Design and Effects

    Author : Ellen F. Grumert; Jan Lundgren; Andreas Tapani; Francesc Soriguera; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Motorway traffic management systems are useful for improving the traffic conditions on urban motorways. One of the most common motorway traffic management systems are variable speed limit systems. READ MORE

  7. 5. Developing Microscopic Traffic Simulation Models for the Transition Towards Automated Driving

    Author : Ivan Postigo; Clas Rydergren; Johan Olstam; Selpi Selpi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Vehicles with different capabilities for automated driving will gradually be deployed in road transportation systems over the coming decades. Mixed traffic conditions may change the characteristics of the traffic flow dynamics. Microscopic traffic simulation is used for studying traffic flow dynamics in transportation systems. READ MORE
