  1. 1. A Method to Identify Future Potential of Vehicle Safety Technology

    Författare :Johan Strandroth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; future crashes; collision avoidance; evaluation; autonomous braking; Delta-v; active safety; vehicle safety technology; CPR;

    Sammanfattning : In the design of a safe road transport system there is a need to better understand the safety challenges lying ahead. One way of doing that is to evaluate safety technology with retrospective analysis of real world crashes. However, by using retrospective data there is the risk of adapting safety innovations to scenarios irrelevant in the future. LÄS MER

  3. 2. Identifying the Potential of Combined Road Safety Interventions - A Method to Evaluate Future Effects of Integrated Road and Vehicle Safety Technologies

    Författare :Johan Strandroth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evaluation; Road Safety Management; Autonomous Emergency Braking; Safety Performance Indicators; System Approach; Prediction; Integrated Safety; Vehicle Safety Technology;

    Sammanfattning : Health loss in the road transport system is one of the leading global public health problems with approximately 1.3 million people killed annually. In order to have a systematical approach to improved road safety, it has become common practice to form road safety management policies that include target setting and evaluation. LÄS MER

    Sammanfattning : This thesis is focused on individual wheel actuators in road vehicles intended for vehicle motion control. Particular attention is paid to electro-mechanical actuators and how they can contribute to improving vehicle dynamics and safety. LÄS MER

  7. 5. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences

    Författare :Dan Brabie; Evert Andersson; Roderick A Smith; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; derailment; bogie design; wheel-sleeper impact; simulation; deviation; vehicle inter-connection; guidance mechanism; substitute guidance; articulated train; railway safety; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.
