Available in PDF, EPUB and Kindle. Book excerpt: Background: In the study of traffic system safety, statistical models have been broadly applied to establish the relationships between the traffic crash occurrence and various risk factors. Most of the existing methods, such as the generalised linear regression models, assume that each observation (e.g. a crash or a vehicle involvement) in the estimation procedure corresponds to an individual situation. Hence, the residuals from the models exhibit independence. Problem: However, this "independence" assumption may often not hold true since multilevel data structures exist extensively because of the data collection and clustering process. Disregarding the possible within-group correlations may lead to production of models with unreliable parameter estimates and statistical inferences. Method: Following a literature review of crash prediction models, this book proposes a 5 T-level hierarchy, viz. (Geographic region level -- Traffic site level -- Traffic crash level -- Driver-vehicle unit level -- Vehicle-occupant level) Time level, to establish a general form of multilevel data structure in traffic safety analysis. To model properly the potential between-group heterogeneity due to the multilevel data structure, a framework of hierarchical models that explicitly specify multilevel structure and correctly yield parameter estimates is employed. Bayesian inference using Markov chain Monte Carlo algorithm is developed to calibrate the proposed hierarchical models. Two Bayesian measures, viz. the Deviance Information Criterion and Cross-Validation Predictive Densities, are adapted to establish the model suitability. Illustrations: The proposed method is illustrated using two case studies in Singapore: 1) a crash-frequency prediction model which takes into account Traffic site level and Time level; 2) a crash-severity prediction model which takes into account Traffic crash level and Driver-vehicle unit level. Conclusion: Comparing the predictive abilities of the proposed models against those of traditional methods, the study demonstrates the importance of accounting for the within-group correlations and illustrates the flexibilities and effectiveness of the Bayesian hierarchical approach in modelling multilevel structure of traffic safety data.

Book Synopsis Introducing Multilevel Modeling by : Ita G G Kreft
Download or read book Introducing Multilevel Modeling written by Ita G G Kreft and published by SAGE. This book was released on 1998-04-07 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first accessible and practical guide to using multilevel models in social research. Multilevel approaches are becoming increasingly important in social, behavioural, and educational research and it is clear from recent developments that such models are seen as being more realistic, and potentially more revealing, than ordinary regression models. While other books describe these multilevel models in considerable detail none focuses on the practical issues and potential problems of doing multilevel analyses that are covered in Introducing Multilevel Modeling. The authors' approach is user-oriented and the formal mathematics and statistics are kept to a minimum. Other key features include the use of worked examples using real data sets, analyzed using the leading computer package for multilevel modeling - "MLn."

Department of Transportation know many of you have traveled great distances to be here. I To me, that shows not only your dedication to the cause, but demonstrates how very important transportation safety is becoming throughout the world. So I am very thankful to the main organizers of this third annual conference -- all of whom are from Sweden: Dr. Hans von Holst of the Royal Institute of Technology; Dr. Ake Nygren of the Karolinska Institute; Dr. Ake E. Andersson of the Institute for Futures Studies; and finally, Dr. Arne Witt16v and Lars Anell from AB Volvo. And let me give a special welcome to our friends from Africa. I will be visiting a number of African nations in January. And while my main mission is to promote trade and investment with the United States, we will be talking about safety, too. Airline safety, for example, is a big concern, as Africa grows and prospers and the demand for air travel expands. We discussed it during recent meetings of the International Civil Aviation Organization in Montreal several weeks ago. And we will do so again during my trip. plan to talk about how my department can help the Also, we many nations of Africa improve highway safety. Africa relies heavily on road transportation. But highway fatalities are very high. And the economic costs are very steep, especially for Africa's fragile, emerging v market economies.

Book Synopsis Eco-city Planning by : Tai-Chee Wong
Download or read book Eco-city Planning written by Tai-Chee Wong and published by Springer Science & Business Media. This book was released on 2011-05-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eco-city planning is a key element of urban land use planning in perspective and of ongoing debate of environmental urban sustainable development with a spatial and practical dimension. The conceptual basis of ecological planning is that we can no longer afford to be merely human-centred in approach. Instead, the interdependency of human and non-human species has forced us to appreciate the ‘rights’ and ‘intrinsic values’ of non-human species in our pursuit for a sustainable ecosystem. This volume has as approach an emphasis on environmental planning policies whereby, for example, energy saving, anti-pollution measures, use of non-car modes, construction of green buildings, safeguarding of nature and natural habitats in urban areas, and use of more renewable resources are promotional norms. Their aims and leading outcome serve to protect the Earth from adverse effects of global warming and different sources of pollution threatening the quality of life of human societies.

Book Synopsis Sustainable Transport Studies in Asia by : Akimasa Fujiwara
Download or read book Sustainable Transport Studies in Asia written by Akimasa Fujiwara and published by Springer Science & Business Media. This book was released on 2013-06-04 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide a good understanding of and perspective on sustainable transport in Asia by focusing on economic, environmental, and social sustainability. It is widely acknowledged that the current situation and trends in transport are not always sustainable in Asia, due in part to the fast-growing economy and the astounding speed of urbanization as well as least-mature governance. As essential research material, the book provides strong support for policy makers and planners by comprehensively covering three groups of strategies, characterized by the words “avoid” (e.g., urban form design and control of car ownership), “shift” (e.g., establishing comprehensive transportation systems and increasing public transportation systems for both intracity and intercity travel), and “improve” (e.g., redesign of paratransit system, low-emission vehicles, intelligent transportation systems, and eco-life). These are elaborated in the book alongside consideration of the uncertainty of policy effects in the future. The book is also valuable for scholars and scientists because of the diverse methodologies presented and proposed herein. Among those are the four-step model with full feedback mechanisms, the bi-level programming model with sustainability goals, data envelopment analysis and stochastic frontier analysis approaches, structural equation models, discrete and/or continuous choice models, copula-based models, survival models, and driving risk models with short-term memory. Using data collected from more than ten Asian cities, including those in both developed and developing nations, the pathway to sustainable transport in Asia gradually becomes clear.
