Book Description
The book's website (with databases and other support materials) can be accessed here. Praise for the Second Edition: The second edition introduces an especially broad set of statistical methods ... As a lecturer in both transportation and marketing research, I find this book an excellent textbook for advanced undergraduate, Master’s and Ph.D. students, covering topics from simple descriptive statistics to complex Bayesian models. ... It is one of the few books that cover an extensive set of statistical methods needed for data analysis in transportation. The book offers a wealth of examples from the transportation field. —The American Statistician Statistical and Econometric Methods for Transportation Data Analysis, Third Edition offers an expansion over the first and second editions in response to the recent methodological advancements in the fields of econometrics and statistics and to provide an increasing range of examples and corresponding data sets. It describes and illustrates some of the statistical and econometric tools commonly used in transportation data analysis. It provides a wide breadth of examples and case studies, covering applications in various aspects of transportation planning, engineering, safety, and economics. Ample analytical rigor is provided in each chapter so that fundamental concepts and principles are clear and numerous references are provided for those seeking additional technical details and applications. New to the Third Edition Updated references and improved examples throughout. New sections on random parameters linear regression and ordered probability models including the hierarchical ordered probit model. A new section on random parameters models with heterogeneity in the means and variances of parameter estimates. Multiple new sections on correlated random parameters and correlated grouped random parameters in probit, logit and hazard-based models. A new section discussing the practical aspects of random parameters model estimation. A new chapter on Latent Class Models. A new chapter on Bivariate and Multivariate Dependent Variable Models. Statistical and Econometric Methods for Transportation Data Analysis, Third Edition can serve as a textbook for advanced undergraduate, Masters, and Ph.D. students in transportation-related disciplines including engineering, economics, urban and regional planning, and sociology. The book also serves as a technical reference for researchers and practitioners wishing to examine and understand a broad range of statistical and econometric tools required to study transportation problems.

Book Description
The primary purpose of the Manual of Classification of Motor Vehicle Traffic Accidents is to promote uniformity and comparability of motor vehicle traffic accident statistics now being developed in Federal, state and local jurisdictions. This manual is divided into two sections, one containing definitions and one containing classification instructions.

Book Description
Traffic control devices in workzones are intended to provide sufficient guidance to motorists to help prevent collisions, especially with construction operations, and based on study of their use in Illinois, they appear to be meeting the objectives. What has been discovered in assessing workzone traffic control and crashes is that collisions occur more frequently than reports show and in ways not necessarily addressed in previous studies. For the most part, traffic control devices (TCD) within the actual construction area require no changes. They are protecting the workers from the motorists. What leads to collisions inside the work area are reduced lane widths and lack of adequate escape, especially on limited access roadways. As a result, the most frequent type of collision is rear-end, often caused by drivers stopping or suddenly slowing because of distractions. Outside the work area, the problem appears more related to poor driving behavior and need for some improved guidance for motorists, especially within the merge areas. When taking into account the under-reporting of crashes, with the exception of increases in certain manners of collision such as rear-end, the crashes appear no more severe than crashes occurring outside such zones. Crashes with pedestrians (which includes workers) also appear no more likely than in locations without workzones. On the other hand, crash reporting appears unlikely to include portions of the workzone away from the actual construction area. Using a set of crash reports in which the workzone was defined clearly to include the approach, taper, and exit, analysis suggests that crashes are almost as likely to occur outside the actual construction area as within. It is these crashes outside which appeared more severe and more amenable to enhanced traffic control, especially enforcement. The report recommends practices which could reduce crashes in the approach and where changes or reductions in lanes occur. In addition to other recommendations, a model for a process to be used in generating and reviewing workzone traffic controls has been developed.
