Purpose: There are many different risks while working on or close to roads. This is because conditions are very varying on road works and different tasks are being performed at the same time (AV, 2015). According to a survey carried out by SEKO (2011) seven out of ten road workers are worrying about working on or close to roads because of the lack of safety. But the fear is not groundless, according to a survey carried out by Liljegren and Szafran-Kzdrój (2014) 2935 accidents related to road works happened between year 2003-2012 where road workers were involved in 139 of the total cases. Efforts to create a better work environment are taking place daily but there are still road workers that get injured or even killed during work. The aim with this report is therefore to examine how roadworkers safety can be improved during roadworks. Method: This survey is a case study, which aims to illustrate the reality. In order to answer the questioning formulation, three different methods have been used. A literature study was first completed to understand how far previous research has come and after that a document analysis of valid laws and regulations was made. The third method used was qualitative interviews, which is the most important foundation for the result. Findings: Risks that occur in road work zones often arises because of the passing traffic. High speed along with reckless drivers or drivers that act aggressive are great risk factors. These risk factors also contribute to mental illness such as stress and anxiety. Physical problems are also a cause of bad work environment with dusty or noisy surroundings. The shared solution to solve these problems are diversion or to reduce speed even more past road work zones. This is though easier said than done because the road maintenance often wats to keep a high traffic volume during the time a road work is performed. Implications: Risks in road work zones are lower when a traffic diversion is applied or when traffic can pass in a satisfactory way. Unfortunately, these actions are not being applied in such extent as wanted by the road workers. To minimise risks in road work zones the contractors' have to start compile and together ask for higher standards. When traffic diversion can’t be applied must recommended speed be reduced even more. Limitations: All interviews were conducted with people working in the same company but in different business areas, within the county of Jönköping. This was because different opinions about the problem were asked for. It is though difficult to decide whether or not the result is generalizable, because only people within the same county and company were interviewed. / Syfte: När vägarbeten utförs på och intill vägar är riskerna många eftersom platsen varierar samtidigt som flera olika arbetsuppgifter utförs samtidigt (AV, 2015). Enligt en undersökning gjord av SEKO (2011) oroar sig sju av tio vägarbetare för att arbeta på väg på grund av bristande säkerhet. Oron är dessvärre inte obefogad, en studie utförd av Liljegren och Szafran-Kzdrój (2014) visar att det under år 2003-2012 inträffade 2935 olyckor relaterade till vägarbeten och i 139 av fallen var vägarbetare inblandade. Arbetet med att skapa en bättre arbetsmiljö pågår dagligen men det sker ändå att vägarbetare skadas eller omkommer på sin arbetsplats. Målet med arbetet är därför att undersöka hur säkerheten för vägarbetare kan förbättras vid arbete på väg. Metod: Undersökningen är av typen fallstudie, vilket syftar till att belysa verkligheten. För att besvara frågeställningarna och uppnå målet har tre olika metoder använts. Först genomfördes en litteraturstudie för att undersöka var kunskapsfronten inom ämnet ligger idag, därefter gjordes en dokumentanalys av gällande lagar, förordningar och föreskrifter. Den tredje metoden som användes var kvalitativa intervjuer, vilka utgör det största underlaget till resultatet. Resultat: De risker som finns på vägarbetsplatser uppkommer till stor del på grund av den passerande fordonstrafiken. Höga hastigheter är tillsammans med trafikanter som kör hänsynslöst eller uppvisar ett aggressivt beteende stora riskfaktorer. Dessa riskfaktorer bidrar även till att psykiska problem som exempelvis stress och oro uppstår. Även fysiska problem på grund av en dålig arbetsmiljö med damm och buller förekommer. Den gemensamma lösningen är kort “led om trafiken” eller “sänk hastigheten ytterligare förbi vägarbetsplatser”. Det är dock lättare sagt än gjort eftersom väghållaren ofta vill behålla en hög trafikvolym på vägarna samtidigt som vägarbeten utförs. Konsekvenser: När trafiken leds om eller kan passera på ett betryggande sätt minskar riskerna på vägarbetsplatsen, dock görs inte detta i tillräcklig stor utsträckning. För att minska riskerna måste entreprenadföretag samarbeta mer och börja ställa högre krav på väghållaren. Vid de tillfällen då trafiken inte kan ledas om utan måste passera vägarbetsplatsen ska även den rekommenderade hastigheten sänkas i större utsträckning. Begränsningar: Alla intervjuer är genomförda med personer som arbetar på samma företag men inom olika affärsområden inom Jönköpings län. Detta eftersom olika ställningstagande om problemet eftersöktes. Då enbart personer som arbetar inom samma län och företag intervjuats är det svårt att avgöra om resultatet är generaliserbart för andra län och företag av annan storlek.

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. Therefore, in the last decades, anumber of approaches have emerged to support and boost traffic safety towards a system free from fatalities andserious impairment outcomes. ‘Sustainable Safety’ and ‘Vision Zero’ are well-known examples aiming to avoidfatalities within the traffic system and reduce injury severity when a traffic accident is inevitable. However, thenumber of fatalities and seriously injured accidents are still relatively high. More specifically, vulnerable roadusers remain involved in fatal and serious accidents even in industrialized countries. Therefore, further advancesin traffic safety studies are needed. This thesis aims at evaluating the impact of road characteristics, traffic rulesand information provision towards a safer traffic system. The thesis is composed of five scientific papers whichsummarizes the main contributions of this work. / <p>QC 20161109</p>

« La grande majorité des accidents demeure liée aux comportements dangereux des usagers de la route ». Cet énoncé, lapidaire, fait aujourd’hui figure d’évidence au sein de la communauté des intervenants en sécurité routière. Il repose pourtant sur des prémisses discutables. Le problème le plus fondamental réside dans le fait que la recherche des dernières décennies s’est presque toute entière vouée à l’analyse des seuls aspects défaillants de la conduite (l’accident, les infractions, les erreurs et les fautes de conduite, les conducteurs à risque ou dysfonctionnels, les attitudes et traits de caractère incitant à la conduite dangereuse, etc.). Ce faisant, on a fini par oublier qu’il nous restait encore beaucoup de choses à apprendre sur le fonctionnement usuel de la conduite automobile. Comment, en effet, peut-on escompter élucider tous les rouages de la dynamique accidentelle sans avoir au préalable cerné, et bien compris, les mécanismes de la conduite « ordinaire » ? Comment peut-on parvenir à approfondir notre compréhension des comportements de conduite si l’on fait totalement abstraction de toutes les activités courantes, « normales », auxquelles se livrent les conducteurs lorsqu’ils sont au volant de leur véhicule ? C’est dans la perspective de mieux comprendre les comportements de conduite, dans leur complexité et dans leur diversité, que la présente thèse a été réalisée. Y a plus spécifiquement été examinée la question des habitudes en raison de leur prédominance dans l’activité de la conduite, mais également en raison de leur résistance, des obstacles bien concrets qu’elles sont susceptibles d’opposer à tous ceux qui tentent de modifier les comportements individuels de conduite. Des entrevues en profondeur, menées auprès de trente conducteurs et conductrices âgé(e)s de 17 à 54 ans, devaient permettre de répondre, entre autres, aux questions suivantes : De quoi sont constituées les différentes habitudes en matière de conduite automobile ? Quelle place occupent-elles dans la conduite des individus ? En quoi constituent-elles un frein au changement, à la modification des pratiques adoptées ? Quelles sont les dimensions qui participent à leur installation ? Les résultats de l’analyse ont permis de jeter les bases d’un modèle des comportements de conduite où les sensations corporelles se voient conférer un rôle des plus centraux, et où l’habitude – bien davantage caractérisée par la notion de confort que par celles d’automatisme ou de répétition – concourt non seulement à la pérennité, mais également à la régulation des conduites adoptées sur la route. / “The vast majority of accidents remain related to the dangerous behaviors of road users”. This straightforward statement is now accepted as a truism by the road safety community, although it is based on questionable premises. The most basic problem is that the research done during last decades was almost completely focused on analyzing solely the failing aspects of driving – accidents, traffic offences, driving errors and mistakes, high-risk and dysfunctional drivers, attitudes and psychological traits that may lead to dangerous driving, etc. In so doing, we came to forget that we still have plenty to learn about the art of ordinary driving. How can we expect to address the entire process of road accidents without first having identified, and clearly understood, the mechanisms of “regular” driving? How can we deepen our understanding of driving behaviors if we are completely ignoring all the usual, “normal” activities people do as they are driving their vehicles? This thesis was realized with the view to better understanding the driving behaviors, taking into account their diversity and richness. The study more specifically looked into the issue of habits, as they are a significant aspect of driving behaviors, but also as they are resilient, in that they pose real barriers to all those who are trying to change individual driving behaviors. In-depth interviews with 30 drivers, male and female, aged between 17 and 54, were meant to answer the following questions, among others: What are the different driving habits made of? To what extent do they direct driving behaviors? How do they hamper the change or modification of adopted practices? What are the factors that lead them to set in? The results of the analysis laid the foundations of a driving behaviors model in which body sensations take a central role, and the habit – which is more related to the idea of comfort than to ideas of automatism or repetition – contributes not only to the sustainability, but also to the regulation of the various behaviors adopted on the roads.

The purpose of this study was to assess the effectiveness of the Denton County Safety Education Program. Subjects were 117 driving-while-intoxicated offenders who completed this alcohol reeducation program between June 1975 to June 1976. Questionnaires were used as evaluative measures. Data were analyzed in three steps: 1) two two-way ANOVAs with one repeated measure; 2) two Pearson product moment correlations; and 3) a Fisher's Z test. Conclusions of the investigation were that (1) both problem and non-problem drinkers benefited from the program; (2) change of attitude was an important factor in reducing recidivism; and (3) the program was successful in meeting its goals as a means of influencing drinking and driving behavior.

"The purpose of this thesis is to show the general development of safety education in the home, the school, and the community with special reference to the safety program in the Public Schools of Dallas, Texas. In this study of the general development of safety education the writer has treated the problem in the following divisions: (1) History of the safety movement (2) Safety education (3) Public safety education (4) Safety program in Dallas (5) Home safety (6) School safety and (7) Safety program in the Dallas Public Schools. Special consideration was given to the safety program of the Public Schools of Dallas "-- leaf 1.

Recent policy change allows states to spend federal dollars directly on teen-led driver safety efforts and requires regular evaluations of effectiveness. There are currently no standardized instruments to measure change in teen driving behavior relevant to teen leaders. This study serves the Tennessee Department of Safety and Homeland Security, Tennessee Highway Safety Office and their network of teen leaders to empirically test and refine the I Drive Smart survey developed by partners and grounded in the Theory of Planned Behavior (TPB). The survey is designed to be administered by teen leaders to their peers and produce data relevant for use in improving planning as well as tracking changes occurring from their work. The survey measures attitudes, perceptions of social norms (peer, family, and law enforcement), perceptions of behavior control, and both driving and passenger behavior intentions. The I Drive Smart web survey was administered by a group of teen leaders to 175 of their peers. Findings were used to inform local planning and in this quasi-confirmatory study aimed at optimizing the survey. An exploratory factor analysis revealed a four factor model aligned with TPB that explained 61.618% of variation. Item reliability analysis demonstrated high internal consistency for the behavior intention scale with a Cronbach’s alpha of .884. An ordinary least squares regression test found the predictive validity of the identified components to be strong, explaining 64.5% of variation in the model and identifying perceptions of behavior control as the best predictor of behavior intentions, followed by family and peer norms. The behavior control component retained so much variation that the optimized survey assesses both volitional and non-volitional control concepts. Further, teen leaders were able to successfully administer the survey and found data helpful in supporting their planning. This study demonstrates that teen leaders are capable of directing evaluation activities and that the refined version of the I Drive Smart survey has appropriate psychometric properties for teen leaders in highway safety to use. Standard procedures for using the survey are discussed along with recommendations for analysis that includes triangulation with other local data points.

Enligt en rapport från trafikverket förekommer kollisioner vid väghållningsarbeten mellan väghållningsfordon och objekt täckta av väglag. Dessa trafikolyckor kan leda till personskador, skador på infrastruktur och skador på de inblandade väghållnings-fordonen. Som lösning på detta problem har möjligheten att visuellt markera de dolda objekten med förstärkt verklighet undersökts. Olika implementationer och metoder för användning av förstärkt verklighet studerades först för att få en bra upp-fattning om ämnet. En applikation utvecklades därefter till mobiltelefon med opera-tivsystemet Android i utvecklingsmiljön Unity. För förstärkt verklighet i applikat-ionen användes en natural feature tracking implementation av ARCore. Positioner-ingstester utfördes med Mobiltelefonens inbyggda GPS vilket visade en stor felmar-ginal. Applikationen utgår därför från en fast startpunkt inmätt med geodetisk mät-utrustning för ökad positioneringsnoggrannhet. För markering av de dolda objekten användes en lösning med cirkelbaserat skapande av tredimensionella objektmarkörer där cirklarnas radie utgick från startpositionen. Användning av applikationen gav va-rierande resultat beroende på den trafiksituation den används i och avståndet från startpositionen. Objektens position markeras tydligast i situationer där mobiltelefo-nen närmar sig det objekt som ska markeras på en väg i en riktning parallellt med cirkelns radie. Sämre tydlighet uppnåddes i situationer där mobiltelefonen närmar sig på en väg med en riktning parallell med cirkelns tangent eller på öppna ytor likt parkeringsplatser. Positioner för olika testobjekt mättes också med geodetisk mätut-rustning för hög precision för att få tillgång till en testmiljö där pålitligt data kunde hämtas upprepade gånger. Resultaten visar att den implementation av ARCore som finns i applikationen är känslig för avbrott i spårning av omgivningen och kan leda till fel i positionering. Ett fel i avståndsberäkningen finns också i programmet. Där-för är vidareutveckling och mer tester ett krav innan applikationen kan fungera i skarpt läge. / According to a report from Trafikverket collisions occur in road maintenance work with road maintenance vehicles and objects hidden by road conditions. These traffic accidents can lead to personal injury, damage to infrastructure and damage to the road maintenance vehicles involved. As a solution to this problem the possibility of visually marking the hidden objects with the use of augmented reality has been ex-amined. Different implementations and methods for use of augmented reality were first studied to get a good understanding of the subject. An application for mobile telephone was developed with the development platform Unity. The targeted oper-ating system for the mobile telephone was Android. A natural feature tracking imple-mentation of ARCore was used to bring features of augmented reality to the applica-tion. Tests were done to measure the precision of the mobile telephone’s GPS which showed a large margin for error. The application therefore uses a fixed start-ing location which has been measured with geodetic-measuring equipment for in-creased positioning accuracy. To visualize the position of the hidden objects a solu-tion with circle based creation of three-dimensional object markers was used where the radius of the circles originated from the starting position. Use of the application led to varied results which depended on the traffic situation and distance from the start position. The positions of the objects are marked more clearly in situations where the mobile phone is approaching the objects on a road and in a direction par-allel to the circle’s radius. Lower accuracy was generally achieved in situations where the mobile phone was approaching the objects on a road in a direction paral-lel to the circle’s tangent or in open areas like a parking lot. Positions for different test objects were also measured to achieve a test-environment where reliable data could be extracted repeatedly. The results of this study showed that the implemen-tation of ARCore used in this application is sensitive to disruption in the real-world registration of the mobile telephone’s position, which can lead to errors in position-ing. An error in calculating the distance to the objects also exists in the application. Therefore, before the application can be used in a real-life situations further devel-opment and tests are required.

Inledning: Nollvisionen, som Sveriges trafiksäkerhet utgår från, uttrycker explicit att medborgares åsikter, krav och behov ska tas hänsyn till. De studier som undersökt hur medborgarnas åsikter hanteras av den offentliga sektorn har främst visat på ett tvetydigt resultat. Det saknas i stort sett forskning kring medborgares synpunkter angående trafiksäkerhet idag. Syftet med denna studie är att undersöka medborgarnas synpunkter om trafiksäkerhet och hur de relaterar till trafikolyckor och trafiksäkerhetsåtgärder. Metod: 400 synpunkter från Huddinge kommun för perioden 2014-2018 inhämtades och kategoriserades. Detta kompletterades med olycks- och skadestatistik från STRADA och trafiksäkerhetsåtgärder från kommunen. Materialet analyserades utifrån en gatu- och områdesanalys baserad på DeSo-indelningen, med hjälp av GIS. Eventuella samband analyserades vidare med hjälp av regressionsanalyser. Resultat: 78 % av synpunkterna var riktade mot en plats inom kommunens tätorter. Hastigheter på 30- och 40 km/h stod för 54 % respektive 32 % av synpunkterna, men 40 km/h visade på en överrepresentation efter den totala längden på vägsträckan. Synpunkterna kunde kategoriseras i 11 olika kategorier och vanligaste synpunkten var riktad mot hastigheter som utgjorde 38 % av synpunkterna. I de olika Deso-områdena var spannet av synpunkter mellan 0-39 stycken. Regressionsanalyserna visade inte på något samband till synpunkterna i gatuanalysen, men i områdesanalysen visade olyckor på ett R²-värde på 0,254 och trafiksäkerhetsåtgärder ett R²-värde på 0,413. Slutsats: Synpunkterna visade på en stor variation i typ, men det var framförallt hastigheter som bekymrade medborgarna. Det fanns stora skillnader baserat på områden och gator, och dessa skillnader kunde inte förklaras utifrån olycksstatistiken. Studien visade på att socio-ekonomiska faktorer delvis kan ligga bakom motivationen till synpunkterna. Kommunens trafiksäkerhetsåtgärder stämde delvis överens med synpunkternas karaktär och områdesplats, dock inte i hög grad på gatunivå. Det kan indikera att kommunen försöker åtgärda synpunkterna eller att medborgarnas syn på trafiksäkerhet delvis stämmer överens med kommunen. / Introduction: The zero-vision policy, on which Sweden’s traffic safety is based upon, expressly states that citizens’ opinions, demands and needs should be taken into consideration. Studies that have investigated the management of public opinions have mostly shown an ambiguous result. The empirical evidence for citizens’ opinions regarding traffic safety is largely lacking as of today. The purpose of this study is to investigate citizens’ opinions regarding traffic safety and how they relate to traffic accidents and road safety measures. Method: 400 opinions were gathered and categorised from Huddinge municipality for the period 2014-2018. This was supplemented by accident and injury statistics from STRADA and road safety measures from the municipality. The data was analysed using a street analysis and a regional analysis, based upon the DeSo classification, using GIS. Correlations were further investigated using regression analyses. Results: 78 % of the opinions were aimed at a place within the municipality’s urban areas. Speed limits of 30- and 40 km/h accounted for 54 % and 32 % respectively of the opinions, but 40 km/h showed an overrepresentation after the total length of the road section. The opinions were categorized into 11 different categories and the most common opinion was regarding speed and accounted for 38 % of the opinions. In the various DeSo-areas the range of opinions was between 0-39. The regression analyses did not show any relationships towards the opinions in the street analysis, but in the area analysis traffic accidents showed an R²-value of 0.254 and road safety measures an R²-value of 0.413. Conclusion: The opinions showed a great variation in type but is was mainly speeds that worried the citizens. There were large differences based on area and streets, and these differences could not be explained by traffic accidents. This study showed that socio-economic factors could partly underlie the motivation behind the opinions. The municipality’s road safety measures were partly in line with the nature of the opinions and their DeSo location, but not to a great extent at street level. This may indicate that the municipality is trying to address the opinions or that the citizens’ view of traffic safety is partly in line with that of the municipality.

Uma parcela significativa dos acidentes de trânsito nas rodovias ocorre devido à saída de veículos da pista, o que pode resultar em choques com obstáculos fixos, quedas em espaços vazios, tombamento, capotagem, etc. Esse tipo de acidente é, em geral, grave, em razão das altas velocidades desenvolvidas nas rodovias. Cerca de 1/3 dos acidentes rodoviários com vítimas fatais nos Estados Unidos resultam de saída de pista. No Brasil, estima-se que 30% dos acidentes rodoviários estão relacionados com saída da pista, sendo esse valor da ordem de 25% nos casos dos acidentes com vítimas fatais. Neste trabalho é apresentado o Modelo QRSP (formado pelas letras iniciais das palavras: Quantificação - Risco - Saída - Pista) em rodovias. O modelo permite quantificar o nível de proteção existente em cada segmento particular da rodovia (análise microscópica) e, a partir dessa informação, quantificar o nível de proteção considerando trechos longos (análise macroscópica). No modelo desenvolvido, a avaliação é feita considerando separadamente os dois lados da pista (direito e esquerdo), podendo os resultados serem compostos no caso da quantificação de trechos longos. O modelo foi desenvolvido para o caso de rodovias de múltiplas faixas por sentido (denominadas comumente de pista dupla), podendo, no entanto, também ser empregado no caso das rodovias de duas faixas e duplo sentido (rodovias de pista simples). O modelo QRSP permite determinar parâmetros não fornecidos pelos métodos ABNT (2007) - norma brasileira - e AASHTO (2002) - norma americana, proporcionando, dessa forma, uma melhor quantificação do risco na saída de veículos da pista. A análise dos resultados fornecidos pelo modelo QRSP mostra que o mesmo representa a realidade de maneira satisfatória. As informações quantitativas fornecidas pelo modelo são de grande utilidade na elaboração de projetos de melhoria das características das laterais de rodovias existentes, bem como na preparação de projetos de novas rodovias. / A significant portion of road traffic accidents on highways occurs because of the exit of vehicles from the runway, which may result in collisions with fixed obstacles, falls in empty spaces, overturning, roll over, etc. This kind of accident is in general quite severe, due to the high speeds on highways. Approximately one third of road accidents with fatalities in the United States result from the runway exit. In Brazil, it is estimated that 30% of road accidents are also related to the runway exit, bringing this value at 25% in the cases of accidents with fatal victims. The QRRE that stands for Quantification the Risk in the Runway Exit of vehicles on highways is presented in this research. The model allows to quantify the level of protection in each particular segment of the highway (microscopic analysis) and from this information, it permits to quantify the level of protection considering long segments (macroscopic analysis). In the developed model, the assessment is done considering separately the left and right sides of the runway, and the results can be compounded in the case of long segments quantification. The model was developed for the case of multilanes highways in each direction, however, this model can also be used in the case of two lanes highways with two-ways direction. The QRRE model allows to determine parameters that are not provided by the methods ABNT (2007) - Brazilian standard, - and AASHTO (2002) - American standard, which provides a better measurement of risk in the exit of vehicles from the runway. The results obtained by QRRE model show that it clearly represents the reality. The quantitative information provided by the model are useful for the development of projects in order to improve the characteristics of the roadside highways available, and the development of projects for new highways.
