A fundamental relationship has been developed that explains road accident statistics in developed and developing countries. The model uses two variables, traffic hazard measured as deaths per vehicle and motorization measured as vehicles per person, to estimate personal hazard as deaths per person. Special cases of the model are those by Smeed, Trinca et al., and Koornstra. The model of fatalities has two extremes. Early motorization has high traffic hazard and personal safety is low and increasing. Full motorization is characterized by a moderate and falling traffic hazard and a low and decreasing personal safety. Between these extremes, there is a maximum number of fatalities per population. Models for personal injury and total road accidents in developed countries appear to follow a similar trend. Available world data fit the proposed relationships well. The models allow planners and engineers to estimate the future maximum road fatalities for developing countries. The model has been extended to incorporate an automobile ownership model that explains some of the growth in motorization. A traffic hazard model is also outlined, in part on the basis of the ideas developed by Koornstra. The extended models should allow a more detailed analysis of some of the social and engineering factors that contribute to road safety.

The priorities in the design of more sustainable buildings are quite dependent on the specific social context. In developing countries, the sustainability concept and priorities in the residential buildings sector are quite different from the ones of the developed countries, since there are still basic needs to answer. Therefore, this research is aimed at contributing to a better understanding of the concept of social sustainability in the residential building sector of the developing countries. A methodology to define and prioritise the social sustainability indicators is proposed and applied in the context of Palestine. The presented methodology is based on the sustainability indicators of international standards, on the most well know building sustainability assessment methods and in the analysis of their application to a specific context. It includes a methodology to prioritise the list of social indicators, by considering the expectations of two groups of building stakeholders: designers and building users. At the end, this research proposes a framework of social aspects to consider in the design of more sustainable residential buildings in West Bank, Palestine that is composed of twenty-one indicators, distributed among six sustainability categories and ranked according to their weight in the overall of sustainability level.

Poverty is no longer fashionable even in the less developed countries of the world. The world has deemed poverty-ridden regions of the world as ‘anathema', forbidden, and ignoble. At the same time ways to get out of the menace are regularly strategised over a period of time. The developed countries of the world had been able to nip poverty to the bud significantly, but the developing countries still have a lot to do so as to overcome the menace. Poverty in the developing countries operates in a cycle of repetitions. This makes it difficult to curtail. How can poverty be reduced in the developing countries? This study reveals the reason while poverty has become a domestic phenomenon in developing countries and the way forward. The theory on poverty is evaluated alongside the present economic situation in Africa. The cycle of poverty, which includes the social cycle of poverty (SCP), political cycle of poverty (PCP), and the economic cycle of poverty (ECP), are examined. This study analyses the strategies to break the cycle of poverty in Africa and other developing countries.

Abstract The risk of becoming involved in an accident emerges when elements of the transport system do not operate properly (man – vehicle – road – roadside). The road, its traffic layout and safety equipment have a critical impact on road user safety. This gives infrastructural work a priority in road safety strategies and programmes. Run-off-road accidents continue to be one of the biggest problems of road safety with consequences including vehicle roll-over or hitting a roadside object. This type of incident represents more than 20% of rural accidents and about 18% of all road deaths in Poland. Mathematical models must be developed to determine how selected roadside factors affect road safety and provide a basis for new roadside design rules and guidelines.

This paper examines the socio-demographic and economic factors affecting tobacco consumption in a developing country like Burkina Faso compared to a developed country like Canada. Using nationally representative data from the 2016 round of Burkina Faso’s Demographic and Health Survey (DHS) and the Canadian Community Health Survey (CCHS) 2015-2016, we estimated multivariate fixed effects models to identify the social and economic factors associated with tobacco consumption in these countries. We find evidence that age has an inverted U-shaped positive effect on cigarettes consumption in both countries with a peak at 24-35 years old in Burkina Faso and a peak at 40-54 years old in Canada. Second, being single increases the consumption of cigarettes while education and employment reduce cigarettes consumption in both countries. The gender gap in tobacco consumption between men and women is larger in Burkina Faso (5.021 cigarettes) compared to Canada (1.45 cigarettes). Third, while income have a negative impact on cigarettes consumption in Canada, it displays a U-shape effect in Burkina Faso. Hence, the social and economic context should be considered by the international organization while addressing the issue of smoking in developed and developing countries.

Road safety refers to the idea of methods and solutions to protect road users from being injured or killed in road accidents. Road users include pedestrians, cyclists, rickshaw and van drivers, and riders of public transport systems such as buses, trams, etc. According to the World Health Organization, more than one million people die in road accidents every year and about 50 million people are injured. Road accidents are identified as one of the major obstacles to sustainable development in Bangladesh. In developing countries such as Bangladesh Road, Safety is much lower in developing or underdeveloped countries and the rate of casualties in road accidents is much higher than in developed countries. The scenario is getting serious day by day. Therefore, Dhaka City has been witnessing tremendous growth in population and physical expansion. This study uses the qualitative research theory and the idea of sustainable development as analytical tools. The research was conducted to analyze and discuss road safety in Dhaka. The research method used in the research is descriptive qualitative research with various primary and secondary sources of the studies. This research resulted in the various aspects of road safety in Bangladesh. The differences between theory and practice, domestic legal arrangements as well judicial decisions.

Road Accident is an all-inclusive disaster with consistently raising pattern. In India according to Indian road safety campaign every minute there is a road accident and almost 17 people die per hour in road accidents. There are different categories of vehicle accidents like rear end, head on and rollover accidents. The state recorded police reports or FIR’s are the documents which contains the information about the accidents. The incident may be self-reported by the people or recorded by the state police. In this paper the frequent patterns of road accidents is been predicted using Apriori and Naïve Bayesian techniques. This pattern will help the government or NGOs to improve the safety and take preventive measures in the roads that have major accident zones.

Explosive development of computer technologies and their availability made it possible to extensively focus nowadays on emerging state-of-the-art technologies, digitalization, artificial intelligence, and automated systems, including in the field of road safety. It would be reasonable to implement some technical devices in this respect to remove human factor and automate some procedures completed at the scene of a road accident. Automatically filled up road accident inspection records and, mainly, diagrams of the accident will reduce time required for the examining inspector and remove human factor. Ultimately, an automated road accident data sheet is suggested to be established. To tackle the issues above requires a technique to determine whether the produced damages to the car body result from the same road accident. The fact remains that there are circumstances when even vehicle trace examination would not do the job, in case of multiple corrosive damage to the body. In view of the above, a technique designed to determine whether the damages produced are caused at the same point of time gains its ground. A technique for a time-related corrosion examination is offered herein to cut expenditures for diagnostics and expert examination of road accidents. That will also eliminate the matters of argument with respect to the road accident evaluation in court. Among added benefits of the technique are that it is simple, quick to implement, and requires no human involvement. It is a well-established fact that each chemical element or a mixture of substances has its own timeinvariant color attributes which allows to determine availability of one or another substance during corrosion of metal surfaces, by emission from the surface in question.

O Protocolo de Kyoto surge em 1997 como uma pretensa solução para o aquecimento global, Apenas um dos seus mecanismos permite a participação direta dos países em desenvolvimento: o Mecanismo de Desenvolvimento Limpo (MDL). A proposta deste mecanismo é que os países em desenvolvimento possam contribuir para a redução de gases do efeito estufa usando financiamento dos países desenvolvidos e, ao mesmo tempo, promovam o desenvolvimento sustentável. No entanto, não há um consenso os atores sociais envolvidos sobre a eficácia dos projetos MDL. Um número crescente de ONGs os critica, argumentando que não há contribuição para o meio ambiente global e para o desenvolvimento sustentável com o MDL. Este trabalho apresenta os resultados de uma investigação que analisou, através de um estudo de caso comparativo, dois diferentes projetos MDL na América Latina: o Projeto Plantar, no Brasil, e o Projeto Fray Bentos de Biomassa, no Uruguai. Os casos têm pelo menos um ponto comum: ambos envolvem conflitos socioambientais entre empresas privadas e ONGs sobre plantações de eucalipto em escala industrial. Através de revisão bibliográfica e documental, entrevistas com os principais atores envolvidos em cada caso, e da observação não participante, este artigo tenta analisar as principais semelhanças e diferenças entre estes conflitos. Observa-se que, não obstante as diferenças marcantes existentes, os casos são ligados em aspectos-chave, a exemplo da contestação ao modelo de desenvolvimento apoiado pelos projetos de MDL e da forma de contestação utilizada pelos integrantes do movimento social ambientalista de oposição. Palavras-chave: Conflitos socioambientais; Mecanismo de Desenvolvimento Limpo (MDL); América Latina. Abstract The Kyoto Protocol comes up in 1997 as a supposed solution to global warming. Only one of its mechanisms allows direct participation of developing countries: the Clean Development Mechanism (CDM). The purpose of this mechanism is that developing countries can contribute to reduce Greenhouse Gas Emissions using funding from developed countries and, at the same time, promote sustainable development. However, there is not a consensus on CDM projects effectiveness among the social actors involved. A growing number of NGOs criticize them, arguing that there is not any contribution to the global environment and sustainable development with the CDM. This paper presents the results of an investigation that examined, through a comparative case study, two different CDM projects in Latin America: Plantar Project in Brazil and the Project Biomass Fray Bentos in Uruguay. The cases have at least one point in common: both involve social and environmental conflicts between private companies and NGOs on eucalyptus plantations in industrial scale. Through literature and documentary review, interviews with key actors involved in each case, and non-participant observation, this article attempts to analyze the similarities and differences between these conflicts. It is observed that, despite marked differences, the cases are linked to key aspects, such as the challenge to the development model supported by the CDM projects and the contestation methods used by the social environmentalist movement of opposition. Keywords: Social Environmental Conflicts; Clean Development Mechanisms (CDM); Latin America.


In India road accidents are very serious problem because of large population and high traffic density of vehicles. Most of the road accidents occur mainly due to the negligence of driver and poor infrastructure only a few accidents occur due to the technical error of vehicles. The main purpose of this research paper is prevention of road traffic accidents and improvement of road safety in Shimla. Road safety is very important aspect of today’s life, so it is important that everybody should aware about road safety. To do this study a section of 12km length is chosen between Panthaghati to Dhalli in district Shimla on NH 5 where accidents black spots are identified for the section by analyzing secondary data used to prevent road accidents. In this study primary data is used for observing the road conditions and secondary data is used to find accidents black spot. Black Spot is a point or a place on the road where road accident occurs repeatedly one after another which is known as accident black spot. To identify these black spots we use weighted severity index (WSI) method. It is one the most reliable and effective method for determining the most proven accidents black spots. Shimla is a hilly area and it has narrow roads, blind curve and black spots which increase the chances of road traffic accidents. In past recent years road traffic accidents are increasing in Shimla and this study deals with identification of major issues causing road traffic accidents. This research paper helps to improve the road safety in Shimla because in this study the analysis has been done to identify the major problems responsible for gradually increasing road accidents. This research paper is also used in future research paper as reference purpose and it will also provide an overview to other researchers who want do their research on similar kind of topics.

Underreporting of road accidents has been widely accepted as a common phenomenon. In many developing countries this remains a critical problem as inappropriate information regarding road accidents does not provide a base to analyse its root causes. Therefore, effectiveness of implemented interventions are always questionable. In Pakistan, responsibility of collecting initial information regarding road accidents lies with the Police Department; however, reported figures are reflecting underestimation of the situation. This chapter reports the effectiveness of prevailing approaches for recording accident information in developing countries like Pakistan, India and Bangladesh, etc. Furthermore, it presents a unique methodology that has been adopted in Karachi for recording road accident information through an institute established on the notions of public-private partnership. Various features of that unique data collection mechanism are presented along with the discussion of some success stories, where the collected data has contributed significantly in improving road safety conditions.
