  1. 1. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

    Författare :Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
    Nyckelord :Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.

  4. 3. Modelling of Traffic Performance for Swedish Roads and Motorways

    Författare :Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. A Traffic Simulation Modeling Framework for Rural Highways

    Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Other technology;

    Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER

  7. 5. Are uncertain uncertainties useful? : towards improved quality assessment of spatial data

    Författare :Britt-Inger Rönnbäck; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : A decision is usually based on some kind of information. In the decision- taking phase it is important to know the extent to which the information about the different alternatives that are to be decided on is reliable. LÄS MER
