This unique book explains how to fashion useful regression models from commonly available data to erect models essential for evidence-based road safety management and research. Composed from techniques and best practices presented over many years of lectures and workshops, The Art of Regression Modeling in Road Safety illustrates that fruitful modeling cannot be done without substantive knowledge about the modeled phenomenon. Class-tested in courses and workshops across North America, the book is ideal for professionals, researchers, university professors, and graduate students with an interest in, or responsibilities related to, road safety. This book also: * Presents for the first time a powerful analytical tool for road safety researchers and practitioners * Includes problems and solutions in each chapter as well as data and spreadsheets for running models and PowerPoint presentation slides * Features pedagogy well-suited for graduate courses and workshops including problems, solutions, and PowerPoint presentations * Equips readers to perform all analyses on a spreadsheet without requiring mastery of complex and costly software * Emphasizes understanding without esoteric mathematics * Makes assumptions visible and explains their role and consequences

Hardbound. This three part monograph aims to enable road safety researchers and professionals to interpret correctly the results of one of the main sources of knowledge about the effect of road safety engineering measures, the observational Before-After study.Part I, ESSENTIALS - contains information the author regards as essential for forming an opinion of results obtained by others, and for planning and analysing such a study. This is written to be accessible to all.Part II, ADAPTATIONS OF CONVENTIONAL APPROACHES - explains how to avoid the errors and improve the results obtained from the predominant methods currently used. This Part employs algebra and statistical analysis.Part III, ELEMENTS OF A NEW APPROACH - presents new approaches to improve future methods of observation and analysis.
