  1. 6. An Ontological Approach to Safety Analysis of Safety-Critical Systems

    Författare :Jiale Zhou; Kristina Lundqvist; Ibrahim Habli; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hazard analysis; ontologies; safety-critical systems; safety requirements elicitation; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical systems (SCSs) have become an intrinsic part of human dailylife in multiple domains, such as automotive, avionics, and rail industries. Such systems are not only required to implement the functionality they should provide, but also have to satisfy a set of safety requirements in order to ensure the mitigation of hazardous consequences.

  3. 7. 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

  4. 8. Safety at Rail-Road Level Crossings

    Författare :Mohammad Shahriari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver behaviour; risk analysis; traffic safety; rail road crossings; safety;

    Sammanfattning : Safety related to traffic at rail/road level crossings has long been a major issue for rail operators all over the world. Eliminating these level crossings entirely would be a desirable solution. However converting them into separate types is very expensive and not reasonable in many cases, e.g. LÄS MER

  5. 9. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

    Författare :Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

    Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

  7. 10. Specifying Safety-Critical Heterogeneous Systems Using Contracts Theory

    Författare :Jonas Westman; Mattias Nyberg; Mats Heimdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contracts; Heterogeneous Systems; Safety; Architecture; Requirements; Specification; Elements; Compositional; IEC 61508; ISO 26262; Kontrakt; Heterogena System; Säkerhet; Arkitektur; Kravhantering; Specifiering; Element; Kompositionell; IEC 61508; ISO 26262; Machine Design; Maskinkonstruktion;

    Sammanfattning : Requirements engineering (RE) is a well-established practice that is also emphasized in safety standards such as IEC 61508 and ISO 26262. Safety standards advocate a particularly stringent RE where requirements must be structured in an hierarchical manner in accordance with the system architecture; at each level, requirements must be allocated to heterogeneous (SW, HW, mechanical, electrical, etc. LÄS MER
