Road safety is a major issue affecting the road sector. Road accidents remain a serious impediment to sustainable human development in many of the developing member countries (DMCs) of the Asian Development Bank (ADB). Road accidents continue to be an important social and economic problem in developing countries like India. Growth in the number of motor vehicles, poor enforcement of traffic safety regulations, poor quality of roads and vehicles, and inadequate public health infrastructures are some of the road safety problems facing in India. The object of this Thesis is to present a status report on the nature of the government policy towards the Activity plans implemented till now and which has to be implemented later for the reduction of road fatalities and for the safe roads, and also giving the guidelines for financing of remedial measures, institutional framework, physical characteristics of the road, traffic control and calming measures, road safety education and enforcement issues. The aim of the Activity plans is to analyze the present situation of road safety in India and to indicate main problems in individual sector of the Activity implemented by comparing and taking the examples of some of the ASEAN Region who are successed in implementing in the individual sectors. The effect of the programme to real safety situation is estimated, and further plans could be corrected if it is necessary. Implementation of the goals for the coming years to reduce the number of accidents at maximum extent and give people, the safe and the steady flow of traffic in India. The vision of a tremendous change next 5 to 10 years is based on a big potential for improvement and a joint effort of all involved groups on all levels of traffic safety, centrally coordinated by the National Road Safety Authorities. The Action Plan is deliberately divided into 14 key Sectors of activity in broadly the same way as the individual country road safety action plans. The sectors involve many different disciplines and a very wide range of multi sector activities but all are based on applying scientific, methodical approaches to the problem. At the end the thesis gives the recommendations and conclusion for the safe Roads in India

Στόχος της παρούσας διατριβής είναι η μελέτη των οδικών ατυχημάτων και ο προσδιορισμός των επικίνδυνων θέσεων (μελανών σημείων) στο οδικό δίκτυο της Περιφέρειας Δυτικής Ελλάδας. Πιο συγκεκριμένα, πραγματοποιήθηκε καταγραφή όλων των τροχαίων ατυχημάτων στους Νομούς Αχαΐα, Αιτωλοακαρνανίας και Ηλείας για τη χρονική περίοδο 2000 - 2012. Η συλλογή στοιχείων έγινε από τα κατά τόπους Τμήματα Τροχαίας των Αστυνομικών διευθύνσεων κάθε νομού, για ολόκληρο το οδικό δίκτυο, δηλαδή εθνικό, επαρχιακό και αστικό. Έγινε καταγραφή του κάθε τροχαίου ατυχήματος, του αριθμού νεκρών και τραυματιών, της ημερομηνίας και της ώρας του συμβάντος, της ακριβούς τοποθεσίας, όπως επίσης και των συνθηκών οδοστρώματος και των περιβαλλοντικών συνθηκών που επικρατούσαν τη στιγμή του συμβάντος. Τα στοιχεία που συλλέχθηκαν ομαδοποιήθηκαν κατάλληλα και επεξεργάστηκαν στατιστικά. Στη συνέχεια για κάποια τμήματα των εθνικών οδών της ΠΔΕ έγινε προσδιορισμός των μελανών σημείων με διαφορετικές αριθμητικές και στατιστικές μεθόδους. Δεν έγινε μελέτη των μελανών σημείων για όλο το οδικό δίκτυο της ΠΔΕ καθώς κάτι τέτοιο θα ήταν πέρα από τους σκοπούς της παρούσας διατριβής. / This master thesis aims to study road accidents and identify hotspots at Western Greece Region. First, accidents occurred during 2000 - 2012 at Achaia, Aitoloakarnania and Ilia prefectures were recorded. Each record includes date, time, number of fatalities and injuries, specific location, road and environmental conditions at the moment of the accident. Collected data were grouped and analyzed statistically. Then after reviewing several numerical and statistical methods for hazardous location identification, a selection of methods was made and were applied in order to identify hotspots for some parts of the national road network. Subsequently, conclusions about the condition of the Western Greece Region road network, and the causes of accidents were derived. Finally, proposals for treatment and future research were made.

Desejase identificar a relação dos fatores com o grau de severidade de um acidente (danos materiais, sem vítimas fatais e com vítimas fatais) e o impacto de cada classe de fator na ocorrência de um acidente. A intensão é embasar uma análise geoespacial levando em consideração técnicas estatísticas e cartográficas e contribuir para melhorar a qualidade das informações sobre segurança viária no país e seu atual cenário crítico. A estrutura metodológica da pesquisa consiste em três etapas principais: (I) Identificação e determinação de segmentos de trechos críticos, (II) Mapeamento dos fatores contribuintes “via” para o acidente e (III) Investigação e estudo dos fatores contribuintes. Quatro trechos de rodovias do oeste do estado de São Paulo foram escolhidos como área de estudo. Na etapa I propôs-se um método de interpolação espacial de escolha de segmentos de trechos críticos levando a premissa existência da dependência geográfica dos acidentes em consideração. No total, foram identificados oito segmentos de trechos críticos na área de estudo. A etapa II concentrou-se no mapeamento dos fatores contribuintes desses segmentos de trechos críticos. Essa etapa trouxe o caráter tecnológico à pesquisa por fazer uso da integração de geotecnologias e a contribuição das Ciências Cartográficas para os estudos de segurança viária, por gerar informação a partir do mapeamento da localização dos fatores contribuintes. Das quatro classes de fatores (humano, ambiente, veículo e via) as características da via foram escolhidas para serem mapeadas, tendo-se deparado com a ausência de qualquer dado dessa classe de fatores tanto no banco de dados dos acidentes como no boletim de ocorrências. A relação com as outras três classes de fatores foi tratada na etapa III da pesquisa, cujos resultados proporcionaram montar o ranking dos seis fatores contribuintes da via mais frequentes nos segmentos de trechos críticos. Adicionalmente, foram construídos três modelos de regressão logística ordinal para investigar o impacto de cada uma das quatro classes de fatores no grau de severidade do acidente (três graus de severidade). Para isso, o grau foi tratado como variável dependente dos modelos. Quatro variáveis independentes (fatores contribuintes) foram consideradas significativas e escolhidas para compor os modelos: consumo de drogas (da classe de fator contribuinte humano), estado dos pneus (da classe de fator veículo), vegetação (da classe de fator via) e sinalização (da classe de fator via). Por fim, os modelos puderam ser analisados a partir da razão de chances (odds ratio) para complementar as informações e sintetizar os resultados como contribuições da pesquisa. / This research presents a study about the contributing factors of road accidents in order to provide evidences to analyse the behaviour of contributing factors involved in these accidents more specifically in critical sections. The intention is to identify the relationship between those factors and the severity degree of an accident (material damage, no fatalities and fatalities) and the impact of each factor class on an accident occurrence. The aim is to base on geospatial analysis taking into account statistical and cartographic techniques and contribute to improve the quality of the road safety information in the country which has a current critical scene. The methodological structure of this thesis consists of following three main steps: (I) Identification and determination of critical sections segments, (II) mapping “road” contributing factors for each accident and (III) Investigation and study of the contributing factors. Four sections of highways in the west of São Paulo state were chosen as the study area. In Step I, proposed a spatial interpolation method to choose critical sections segments premising the existence of geographical dependence of the considered accidents. In entire, eight critical sections segments were identified in the study area. Step II focused on mapping the contributing factors of these segments. This step brought the technological character to this research by making use of geotechnologies integration and the contribution of Cartographic Sciences to road safety by generating information of the contributing factors location from mapping. Of the four factors classes (human, environment, vehicle and road), the road characteristics were chosen to be mapped, since no data from this factor class was found in both the accident database and the occurrence report. The relation with the other three factors classes was the subject of step III, which results provided a ranking of the six most frequent contributing factors in critical sections segments. In addition, three ordinal logistic regression models were constructed to investigate the impact of each of the four factors classes on the accident severity degree (three severity degrees). For this, the severity degree was considered as the models dependent variable. Four significant independent variables (contributing factors) were chosen to compose the following models: drug consumption (from the human contributing factor class), tire condition (vehicle factor class), vegetation (road factor class) and signaling (road factor class). Lastly, the models could be analysed by the odds ratio method to complement the information and synthesize the results as research contributions.

This student thesis deals with problems of the causes of road accidents and injury in the Czech Republic, and with the possibilities of their elimination. The human is the most dangerous factor of the transportation system. This resulted in the analysis of the causes of road accidents. The safety of the human factor depends on the experience of the driver, appreciating of danger, attention paid to the driving of vehicle, and on the stress of the road-traffic. The basis of the effective accident prevention are traffic safety precautions.

The thesis refers to the issue of road accidents and their prevention in the Czech Republic, seen as a negative phenomenon in modern society. It is divided into two relatively independent parts, theoretical and practical. The theoretical part focuses on a general description of traffic accident and states their main causes. Moreover, it deals with a road accident as a traumatic event having negative effects on life of involved people, especially on the human psyche. At the end of this part you can find basic principles of emergency intervention on casualties of road accidents and organizations which offer free help to road accident casualties. In the practical part of this work there is a study of road accidents that happened in the region of the Czech Republic from the point of view of their causes and the age of the driver.

Road safety is a complex problem. It is influenced mainly by the driver, the vehicle and the road surface. This thesis is focused on the road surface properties and especially skid resistance that directly affect the braking distance and keeping the vehicle in the horizontal curves and thus traffic accidents. The thesis deals with the durability of pavement surface skid resistance, the type of pavement layers and aggregate polishing used in wearing course. The aim of this thesis was to develop the methodology for improvement of road surfaces skid resistance durability and implementation of functional test for their assessment.
