Incidence occurrence and response on urban freeways / Modélisation pour l'estimation des probabilités d'incidents et pour le traitement de leur réponse sur les réseaux d'autoroutes

Christoforou, Zoi 01 December 2010 (has links)
Les recherches en sécurité routière suscitent largement l'intérêt des chercheurs. Indépendamment des techniques de modélisation, un facteur important d'imprécision -qui caractérise les études dans ce domaine- concerne le niveau d'agrégation des données. Aujourd'hui, la plupart des autoroutes sont équipées de systèmes permanents de surveillance qui fournissent des données désagrégées. Dans ce contexte, l'objectif de la thèse est d'exploiter les données trafic recueillies en temps réel au moment des accidents, afin d'élargir le champ des travaux précédents et de mettre en évidence un potentiel d'applications innovantes. À cette fin, nous examinons les effets du trafic sur le type d'accident ainsi que sur la gravité subie par les occupants des véhicules, tout en tenant compte des facteurs environnementaux et géométriques. Des modèles Probit sont appliqués aux données de trafic et d'accidents enregistrés pendant quatre années sur le tronc commun aux autoroutes A4 et A86 en Ile-de-France. Les résultats empiriques indiquent que le type d'accident peut être presque exclusivement défini par les conditions de trafic prévalant peu avant son occurrence. En outre, l'augmentation du débit s'avère exercer un effet constamment positif sur la gravité, alors que la vitesse exerce un effet différentiel sur la gravité en fonction des conditions d'écoulement. Nous établissons ensuite un cadre conceptuel pour des applications de gestion des incidents qui s'appuie sur les données trafic recueillies en temps réel. Nous utilisons les résultats de la thèse afin d'explorer des implications qui ont trait à la propension et à la détection des incidents, ainsi qu'à l'amélioration de leur gestion / Research on road safety has been of great interest to engineers and planners for decades. Regardless of modeling techniques, a serious factor of inaccuracy - in most past studies - has been data aggregation. Nowadays, most freeways are equipped with continuous surveillance systems making disaggregate traffic data readily available ; these have been used in few studies. In this context, the main objective of this dissertation is to capitalize highway traffic data collected on a real-time basis at the moment of accident occurrence in order to expand previous road safety work and to highlight potential further applications. To this end, we first examine the effects of various traffic parameters on type of road crash as well as on the injury level sustained by vehicle occupants involved in accidents, while controlling for environmental and geometric factors. Probit models are specified on 4-years of data from the A4-A86 highway section in the Ile-de -France region, France. Empirical findings indicate that crash type can almost exclusively be defined by the prevailing traffic conditions shortly before its occurrence. Increased traffic volume is found to have a consistently positive effect on severity, while speed has a differential effect on severity depending on flow conditions. We then establish a conceptual framework for incident management applications using real-time traffic data on urban freeways. We use dissertation previous findings to explore potential implications towards incident propensity detection and enhanced management

The response to and recovery from the 2004 Eastern Bay of Plenty flood event : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Emergency Management at Massey University, Palmerston North, New Zealand

Busby, Eric January 2010 (has links)
Incident Management Systems used in New Zealand have their origins in the fire-fighting organisations of the United States of America in the 1970’s. They began in an atmosphere of disciplined quasi-military emergency response organizations. Emergency management research, theory and practice have since evolved to incorporate comprehensive facets acknowledging disasters are about people, individually and collectively and their environment. Emergency Management now includes addressing psycho-social aspects. New Zealand emergency services adopted the Coordinated Incident Management System (CIMS) as a result of a requirement following the Cave Creek disaster of 1995, where a multi- agency response to the event was found to be unsatisfactorily managed. Emergency management in the modern era now requires the orchestration of many and varied agencies and organisations including government and non-government organisations. These organisations are not necessarily suited to command type management styles and during a recovery phase of an incident, an approach involving a coordination style is more appropriate than a command style. An examination of the 2004 eastern Bay of Plenty flood event highlights that improved coordination by using a suitable incident management system benefits the response and recovery process. The Eastern Bay of Plenty community has social and cultural characteristics that impact on the effectiveness of emergency management outcomes. An incident management system that improves communication within the multi-agency organisation and between an emergency management organisation and the disaster-affected communities contributes to overall trauma reduction by stress reduction and facilitating early support and interventions. This allows where necessary, for modern emergency management to use systems that can utilise the unique community cultures, structures and networks that form the dynamic communities that they serve. If disasters magnify pre-existing social and community problems then the incident management system model used in a disaster can determine the degree of magnification.

Är du beredd när det smäller? : Utmaningar inom incidenthantering med fokus på IT-konsultbolag

Nyman, Maja January 2018 (has links)
Information security incident management is important for organizations and its importance is increasing. Information security incidents are increasing both in number and in scope and in 2018 GDPR and the NIS-directive require organizations to report incidents to a supervision authority. This study highlights IT-consulting companies and their vulnerable position as subcontractors. The study aims to address the lack of empirical research in incident management and to inform future theory development. The goal of the study is to answer the research questions (1) what challenges do IT-consultancy companies experience with their incident management? (2) What challenges are specifically related to the GDPR and the NIS-directive? And (3) what challenges are specific for consulting companies? Challenges with the incident management are identified and clarified by qualitative interviews with experts and a survey. The analysis of the results shows that some of the challenges are consistent with previous studies, while some are new and that the survey partly support the experts' opinions. The conclusion of the study is that the majority of the companies’ improvement opportunities are linked to internal and external communication, cost focus, absence of a major incident, awareness, GDPR, the role of consulting company and internationally recognized difficult activities. The research contribution of the study consists of identified challenges in the field of incident management derived from IT-consultancy companies. The result of the study are recommended to IT-consultancy companies that would like to improve their incident management process by gaining an understanding of incident management issues. / En väl fungerande process för incidenthantering är och blir allt viktigare för organisationer. Informationssäkerhetsincidenter ökar både i antal och i omfattning och 2018 träder GDPR och NIS-direktivet i kraft med krav på rapportering av utpekade incidenter till en tillsynsmyndighet. Denna studie belyser IT-konsultbolag och deras utsatta position som underleverantör och syftar till att adressera bristen av empirisk forskning inom incidenthantering och att bidra till en framtida teoriutveckling. Målet med studien är att besvara forskningsfrågorna (1) vilka utmaningar upplever IT-konsultbolag med deras incidenthantering? (2) vilka utmaningar är specifikt relaterade till GDPR och NIS-direktivet? och (3) vilka utmaningar och är specifika för just konsultbolag? Resultatet bygger på kvalitativa intervjuer med experter och en enkätundersökning och resultatet identifierar och tydliggör upplevda utmaningar med bolagens incidenthantering. Analysen av resultatet visar att vissa av bolagens utmaningar överensstämmer med tidigare studier medan vissa är nya och att enkätundersökningen till viss del stödjer experternas utlåtanden. Slutsatsen av studien är att bolagen har flertalet utvecklings- och förbättringsmöjligheter som är kopplade till intern och extern kommunikation, kostnadsfokus, avsaknad av en större incident, medvetenhet, GDPR, rollen som konsultbolag och internationellt erkända svåra aktiviteter. Studiens forskningsbidrag består av identifierade utmaningar inom området incidenthantering hos IT-konsultbolag och resultatet av studien rekommenderas till IT-konsultbolag som, genom att få en förståelse av incidenthanteringens problematik, vill förbättra och utveckla sin process för hantering av incidenter.
