Driving anxiety that has developed following crashes has been studied relatively frequently, but anxiety per se and its effects on driving has not as yet garnered much attention in the literature. The current study included 1121 participants and found higher levels of general anxiety were related to a wide variety of dangerous driving behaviors. While there were clear and expected sex differences on many dangerous driving variables, there were still more such differences with regard to anxiety levels and independent of sex, higher levels of anxiety were associated with greater levels of dangerous driving. Of particular import, it was found that the high anxiety group had caused significantly more crashes and engaged in more DUI episodes than the low and/or medium anxiety groups. Taken as a whole, the results suggest there is a tremendous need for more research in the area of anxiety and dangerous driving and that interventions for highly anxious drivers may well be warranted.

The Dula Dangerous Driving Index (DDDI) was created to measure drivers' self-reported propensity to drive dangerously (Dula & Ballard, in press). In the early stages of development, the DDDI and each of its subscales (Dangerous Driving Total, Aggressive Driving, Negative Emotional Driving, and Risky Driving) were found to have strong internal reliability (alphas from .83 to .92), and there was evidence of construct validity. In Study One, the alpha coefficient of .91 for the DDDI Total scale indicated excellent internal reliability for the measure and good internal reliability was demonstrated for its subscales with coefficient alphas equal to .81 for the DDDI Risky Driving subscale, .79 for the DDDI Negative Emotional subscale, and the DDDI Aggressive Driving subscale. Additionally, convergent and divergent validity was shown for the DDDI, but evidence was weaker for the validity of the separate subscales. Factor analysis demonstrated that the DDDI seemed to measure a unitary construct. In Study Two, coefficients of stability were generated from a four-week test-retest procedure, which were .76 for the DDDI Risky Driving subscale, .68 for the DDDI Negative Emotional subscale, .55 for the DDDI Aggressive Driving subscale, and .73 for the DDDI Total. In Study Three, the percentage of variance accounted for in criterion variables by different models ranged from 13.6% to 47.7%, where the DDDI Negative Emotional and DDDI Total scales frequently accounted for large portions of variance. In Study Four, the percent of variance accounted for in criterion variables by different models ranged from 22.0% to 65.6%, where some of the DDDI scales were regularly found to account for significant variance. Thus, it was concluded that the DDDI is a measure with high levels of internal reliability and reasonable stability across time, and that face, construct, and predictive validity was demonstrated. However, the evidence in support of the present division of subscales was weak, though present. Therefore, should further data fail to produce more substantial evidence for the validity of the DDDI subscales, a singular dangerous driving measure would be warranted, and the number of items should be shortened as guided by results from factorial analysis. / Ph.

Le transport maritime est d'une importance stratégique pour l'économie de l'Union européenne. Chaque année, un milliard de tonnes de pétrole transitent par les ports et les eaux de l'UE et deux milliards de tonnes de marchandises sont chargées et déchargées dans ses ports. C'est pourquoi, depuis le naufrage de l'Amoco Cadiz et les conséquences désastreuses, tant pour l'environnement que pour l'économie qui en découlèrent, l'Union européenne ne cesse de développer et d'intensifier sa politique de sécurité maritime dans le but de mettre un terme à la navigation sous normes, essentiellement par une application effective des règles internationales en la matière. Depuis 1993, l'UE et ses États membres sont au premier plan afin d'améliorer la législation en matière de sécurité du transport maritime de marchandises et substances dangereuses pour éliminer les navires sous-normes, augmenter la protection des équipages, réduire le risque de pollution de l'environnement et veiller à ce que les opérateurs qui suivent les bonnes pratiques ne soient pas désavantagés commercialement par rapport à ceux qui sont prêts à prendre des raccourcis avec la sécurité des navires. Les accidents de l'Erika et du Prestige encouragèrent l'UE à réformer radicalement son régime juridique et à adopter de nouvelles règles et normes de prévention des accidents en mer, en particulier celles impliquant les pétroliers. Depuis plus de trente ans l'UE n'a cessé de renforcer et d'améliorer son arsenal législatif. Elle fit évoluer sa réglementation consécutivement aux divers accidents qui vinrent frapper ses côtes ; c'est pourquoi la sécurité du transport maritime sera toujours en évolution. / Maritime transport has strategic importance for the economy of the European Union. Each year, one billion tons of oil pass through the ports and waters of the EU. Two billion tons of goods are loaded and unloaded in its ports. Because of the disastrous consequences the sinking of Amoco Cadiz has had on the environment and economy, the European Union continues to develop and strengthen its policy on maritime safety in order to put an end to substandard shipping, primarily through the effective application of international rules. Since 1993, the European Union and its Member States are at the forefront improving legislation on the safety of maritime transport of dangerous goods and substances, striving to eliminate substandard ships, increase protection of the crew, reduce the risk of environmental pollution. The EU is insuring operators who are following the best practices, compared to those who are willing to take shortcuts with the safety of ships, are not commercially disadvantaged. Accidents of the Erika and Prestige encouraged the EU to radically reform its legal system and to adopt new rules and standards for the prevention of accidents at sea, particularly those involving tankers. For more than thirty years the European Union has not stopped to strengthen and to improve its legislation in order to better protect itself against the risks of pollution due to maritime transports of dangerous goods. It has updated its regulation consecutivly to several accidents which damaged its coasts ; that is why the safety of maritme transport will always be evolving.

The master‘s thesis focuses on the risks of transporting dangerous goods by road. The introductory part deals with related legislation of the Czech Republic is analyzed, followed by international legislation. In the European Union, the transport of dangerous goods is regulated primarily by the European agreement concerning the International carriage of dangerous goods by road (ADR). Between 2002 and 2019, master‘s thesis analyzes and describes the statistics of traffic accidents with the presence of dangerous goods. Furthermore, this master‘s thesis also analyzes the characteristics of the sources of traffic accident risks, and when activating the risk, the possible effects of traffic accidents and subsequent leakage of dangerous goods are described. In fulfilling the aims of the master‘s thesis, agreement was found in the causes of traffic accidents in statistics and in the literature in the fact that in 80% it is the fault of the human factor. Analysis of a set of 10 large accidents with the presence of dangerous goods using a modified "What, if" method identified impacts on public assets. Based on these identified impacts, measures were proposed that would be appropriate to apply in the public interest.

The task this master’s thesis was evaluated present status safety management system for transport of materials and dangerous substances. I looks this issues like whole in The theoretical part. I want to find all kritical locations. I analysis type of transport, transport routs, driver training, legislation and label the most transport of materials and dangerous substances. I want to found the risk to remove or cushion. I want to proposed preventive measures in the practical part.

[pt] O transporte rodoviário de produtos perigosos é a principal atividade econômica geradora de acidentes ambientais no Brasil. No modal rodoviário, durante o carregamento, o deslocamento e a descarga há combinações de fatores adversos à operação prescritas em normas que representam riscos de incidentes e acidentes que, a cada ano, aumentam suas estatísticas nas estradas brasileiras. Esta pesquisa identificou pontos de controle aplicados nos locais de partida, onde ocorrem os carregamentos, operados por condutores de veículos que transportam etanol com vistas à prevenção de acidentes durante o transporte da carga. A partir da revisão de leis, decretos e normas, e considerando o percurso entre os estados do Rio de Janeiro e de São Paulo, o transporte rodoviário de produtos perigosos foi estudado sob o ponto de vista da teoria de prevenção de acidentes de Haddon e modelos de acidentes do Abiquim, programa Olho Vivo nas Estradas. Por meio de entrevistas com funcionários de distribuidoras de combustíveis, a pesquisa identificou práticas correntes utilizadas por motoristas de caminhões para a checagem das condições gerais dos veículos nos pontos de partida com vistas ao atendimento de normas, legislações e procedimentos de segurança das empresas. Os motoristas revelaram que os acidentes ocorridos nas estradas ou até mesmo nas áreas urbanas não ocorrem por falhas de inspeção no ponto de partida, mas sim devido a imprudência de outros condutores que não respeitam as leis de trânsito. / [en] Since 2015, resulting from industrial expansion and driven by exports and cargo distribution and storage logistics in Brazil, road transport has grown significantly. Among the products that had increased volumes are chemicals that, by their nature, present risks when handled and transported. This increase in demand for cargo transportation was higher in road transport when compared to other modes of transport, such as waterway and rail. The Fig. 1 presents the configuration of the different modal of dangerous cargo transportation in 2015.
