The use of laser scanning and 3D modelling in accident investigationsEyre, Matthew January 2015 (has links)
In order to prevent accidents we need to understand them, this is achieved through effective accident investigation. Accident investigation is a complex process of gathering and evaluating information to determine factors that may have implications on the final event. One of the fundamental aspects in the investigation process is to capture geospatial data of the incident, to document the scene in its current condition, providing the investigation team with a record for future reference. The production of plans have conventionally remained the same, with a surveyor tasked to illustrate a 3D scene with 2D representations. Recent developments in instrumentation have provided the geospatial industry with the means to capture vast amounts of 3D data directly using laser scanning. In addition, there have been considerable advancements in software applications which can be used to process the surveyed datasets. This research evaluates the use of the latest technology in respect of accident investigation applying the methodology to fire related incidents, industrial accidents and mining incidents. This is achieved by using a number of case studies that have been undertaken throughout the timeline of the project and whilst working with industry professionals in the field.

Road Accident Reconstruction and Simulation With and Without EDR DataModak, Anagha Gurunath 23 August 2011 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Road accident reconstruction and simulation investigates the accident causes, suggests improvements in vehicle design and investigates failures in vehicle control and safety systems such as the anti-lock brake system (ABS) and air-bag deployment.
This thesis focuses on analysis of crash data from vehicles not equipped with collision warning systems. Vehicle parameters before and during an accident can be recorded using an Event Data Recorder (EDR) which helps in reconstructing an accident. This tool, installed in the vehicle, records different crash parameters like vehicle speed, lateral and longitudinal acceleration, seat-belt status, and air-bag deployment over a period that spens the accident. This thesis focuses on accident reconstruction with and without EDR data. A simulation software tool called HVE is used to visually recreate the reconstructed accidents. HVE is a platform to execute different accident simulation methods which are used for specific types of simulations. Two such simulation methods, EDSMAC4 and EDHIS, are discussed in this thesis. The former is an important method for vehicle-to-vehicle collisions and the latter is used for analysis of human behavior involved in the accident.
Three real-life accidents were chosen for reconstruction and simulation. They were Bus and Car accident, Three Vehicle accident and Intersection accident. These particular accidents were chosen to represent a diverse selection of accidents based on the following parameters: the locations of the accidents, the vehicles involved in each accident, and the data available. A qualitative analysis of vehicle occupant's behavior is also presented for one of the three accidents. The thesis discusses in detail the reconstruction of these three accidents. Throughout these simulations, the thesis illustrates the advantages and limitations of the EDR and HVE simulation software for accident reconstruction and simulation.

Verktyg i lokalt säkerhetsarbete med särskilt fokus på olycksutredningar / Tools for local safety management with special focus on accident investigationsStrömgren, Mattias January 2013 (has links)
Kommuner har en unik position i säkerhetsarbetet genom att vara nära både medborgarna och de olyckor och skador som drabbar befolkningen. Trots långtgående framsteg inom teknologi och ett etablerat välfärdssamhälle utgör personskador till följd av olyckor ett betydande folkhälsoproblem i Sverige liksom i övriga nordiska länder. De svenska kommunerna har ålagts ett vidsträckt ansvar och förväntas vidta åtgärder inom flera samhällsområden för att värna människornas trygghet och säkerhet. De senaste två decennierna har utvecklingen i allt högre grad inneburit olika former av systematiskt och tvärsektoriellt säkerhetsarbete i kommunerna. I detta arbete används olika verktyg och metoder som hjälpmedel och stöd. Vissa verktyg är obligatoriska att använda enligt lagstiftning medan andra är frivilliga. Denna uppsats syftar till att kartlägga kommunernas användning av några av dessa säkerhetsverktyg, samt att för ett av verktygen – olycksutredning – undersöka i vilken utsträckning några särskilda utredningsmetoder förmår stödja den samlade praktiska hantering som en olycksutredning innebär. Uppsatsen bygger på två delarbeten, varav det ena är publicerat i en internationell vetenskaplig tidskrift och det andra är inskickat för bedömning till en annan tidskrift. Artikel I bygger på en enkätstudie till 1283 tjänstemän i 73 kommuner. En fråga handlade om användningen av 16 olika säkerhetsverktyg. Denna fråga besvarades av 50 % av de tillfrågade personerna. Resultaten tyder på att verktygen skyddsrond, riskanalys och riskinventering hade utbredd användning i samtliga sektorer medan övriga verktyg användes begränsat inom vissa sektorer eller nästan inte alls. Artikel II studerar hur olika olycksutredningsmetoder stödjer den praktiska utredningsprocessen. Analysen grundas i en processmodell särskilt framtagen för utvärdering av metoderna. Slutsatserna stöds av data från 114 tester av sådana metoder i kursen Kvalificerad olycksutredningsmetodik vid Karlstads universitet. Över 170 kursdeltagare från olika branscher har medverkat i testerna, som en del i undervisningen. Resultaten visar att bland de bedömda metoderna så är det endast metoderna Avvikelseutredning och STEP som ger ett bra stöd i hela utredningsprocessen. Övriga metoder stödjer huvudsakligen endast själva analysdelen i en olycksutredning. De sammanfattande slutsatserna visar att kommunerna använder sig av verktyg i sitt säkerhetsarbete, men att endast ett fåtal av verktygen används brett i alla kommunsektorer. Bland de undersökta metoderna för verktyget olycksutredning konstateras att det finns stora skillnader i hur dessa stödjer utredningsprocessen. Flera metoder borde kanske snarare benämnas olycksanalysmetoder, istället för olycksutredningsmetoder, då de främst ger stöd för själva analysdelen i utredningsarbetet. / Municipalities have a unique position in safety work by being close to both the citizens and the accidents and injuries that affect the population. Despite far-reaching advances in technology and an established welfare state, injuries resulting from accidents constitute a significant public health problem in Sweden as well as in other Nordic countries. Swedish municipalities are subjected to wide-ranging responsibilities and are expected to take action in a number of societal areas to safeguard people's safety and security. The last two decades are increasingly characterized by systematic and cross-sectorial safety work of various forms in municipalities. In this endeavor a variety of tools and methods intended to aid and support safety work have been introduced. Some tools are required by law while others are optional. This thesis aims to identify to what extent local authorities utilize a number of these safety tools, and secondly to examine whether a set of particular methods aimed to guide one of the tools – accident investigation – are actually supportive to the entire practical investigative process. The thesis is based on two papers, the first of which has been published in an international scientific journal, and the second has been submitted to another journal. Article I is based on a survey targeting 1283 officials in 73 municipalities. One question was about the use of 16 different safety tools. This question was answered by 50 % of the officials. The results show that safety round, risk analysis and risk inventory were reported to be used frequently in all sectors while other tools were used only in certain sectors or virtually not at all. Article II analyzes how different accident investigation methods support the practical investigative process. The evaluation is based on a process model intended to illustrate this process. The analysis comprises data from 114 tests of nine selected methods taught in a recurrent course entitled Advanced Accident Investigation Methodology at Karlstad University. More than 170 participants representing various industries and sectors were involved in the tests. The results show that among the nine assessed methods, only Deviation Analysis and STEP gives good support throughout the entire investigative process. Other methods provide support primarily during the analysis phase of an accident investigation. In summary, our findings show that local authorities make use of safety tools, but only a few of the tools are broadly used across all municipal sectors. Regarding the assessed methods of the tool accident investigation it can be concluded that there are major differences in their way to support throughout the investigative process. It is suggested that several methods should rather be described as accident analysis methods instead of accident investigation methods since they provide support mainly for the analysis step.

Oorsake van padongelukke met verwysing na die R44 tussen Somerset-Wes en KlapmutsVogel, Liesel 12 1900 (has links)
Thesis (MScEng)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: South Africa, and other developing countries, experience great problems
concerning road traffic accidents. Despite road safety campaigns like Arrive
Alive being launched, accident rates do not decline significantly and the problem
is predicted to get worse. This study is done on a road in the Western Cape, the
R44, to investigate the causes of road accidents. The causes of the accidents
are deduced from the accident reports and relationships are sought with other
factors. The results of this study are risk factors (human-, environment- and
vehicle factors) for the 14 accident types that occurred on the R44, as well as
measures to prevent road accidents. It has been found that the human factor
plays the biggest role in road accidents. Out of the 404 accidents analysed,
77.7% were caused by human factors, 8.7% by unknown factors, 7.2% by
environmental factors and 6.4% by vehicle factors. The problems experienced
with the data quality are reported and recommendations concerning it are made. / AFRIKAANSE OPSOMMING: Suid-Afrika en ander ontwikkelende lande ervaar groot probleme met
verkeersongelukke. Ten spyte van veldtogte soos Arrive Alive wat geloods word,
neem ongelukskoerse nie beduidend af nie, en daar word voorspel dat die
situasie nie gaan verbeter nie. Hierdie studie is op 'n pad in die Wes-Kaap, die
R44, gedoen om die oorsake van padongelukke vas te stel. Die oorsake van
ongelukke i s van die ongeluksvorms a fgelei, en verwantskappe is gesoek met
ander faktore. Die resultate van die studie is risikofaktore (menslike-,
omgewings- en voertuigfaktore) vir die 14 ongelukstipes wat op die R44
voorgekom het, asook voorkomingsmaatreëls om padongelukke te voorkom.
Daar is gevind dat die menslike faktor die grootste oorsaak van ongelukke is. Uit
die 404 ongelukke wat geanaliseer is, is 77.7% van die ongelukke deur menslike
faktore, 8.7% van die ongelukke deur onbekende faktore, 7.2% van die
ongelukke deur omgewingsfaktore en 6.4% van die ongelukke deur
voertuigfaktore veroorsaak. In hierdie studie is probleme ondervind met die
datakwaliteit, en daaroor is verslag gedoen en aanbevelings gemaak.
