  1. 21. Toward safety promotion among road users : epidemiology and prevention of road traffic injuries in Iran

    Författare :Davoud Khorasani Zavareh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vulnerable road-user; capture-recapture method; surveillance; system; approach; coordination; road-user safety; laypeople interaction; pre-hospital services; grounded theory;

    Sammanfattning : Road traffic injuries (RTIs) are a major public health problem. Iran has one of the highest RTI mortality and morbidity rates in the world. LÄS MER

  3. 22. Mathematical modelling of operating cycles for road vehicles

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy estimation; transport application; operating cycle; autoregressive models; road mission; stochastic models;

    Sammanfattning : Difficulties that commercial vehicles are facing in meeting regulation standards require ad-hoc solutions. Emissions can be dramatically lowered if the characteristics of the transport application are known in advance. LÄS MER

  4. 23. The operating cycle representation of road transport missions

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Sammanfattning : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.

  5. 24. Modeling Driver Behavior : A Control Theory Based Approach

    Författare :Katja Vogel; Lars Åberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the project, which led to this thesis, was to suggest a micro-level driver behavior model, which would allow estimating the effects of safety measures on road traffic safety. The empirical research on driver behavior should be conducted in urban areas, because they are much less explored than rural areas, even though most non-fatal accidents occur in urban areas. LÄS MER

  7. 25. A Microdata Analysis Approach to Transport Infrastructure Maintenance

    Författare :Kristin Svenson; Lars Rönnegård; Karin Edvardsson; Nasir Gharaibeh; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Infrastructure Asset Management; Transport Infrastructure Maintenance; Statistical Modeling; Microdata Analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Maintenance of transport infrastructure assets is widely advocated as the key in minimizing current and future costs of the transportation network. While effective maintenance decisions are often a result of engineering skills and practical knowledge, efficient decisions must also account for the net result over an asset's life-cycle. LÄS MER
