The report includes results of two studies of construction zone traffic control. The first study involved analysis of traffic accidents occurring in 79 zones in seven states. Results indicate a before to during accident rate increase of 6.8%. Results also include breakdowns by accident types, severity, light conditions, roadway type, area type, work area roadway type, construction type and state. The second study was field testing of speed reduction methods. Speeds, erratic maneuvers and conflicts were measured at three sites--an urban freeway, a rural freeway, and an urban street. The field studies examined the effect of the following construction zone parameters on vehicle speeds and safety: Sequential flashing arrow boards; speed zoning (advisory and regulatory); enforcement; transverse striping; obliteration of nonappropriate pavement markings; taper length; lane width reduction; and active warning of speed zoning. Recommended guidelines for construction zone traffic controls are also included.

The study involves the development of an accident data reporting process for use in construction, maintenance, or utility work areas. The process is based on the results of a 9 state survey which collected information on practices and procedures which were in use in those states.

The report presents a prioritized listing of twenty problem statements relating to traffic safety in construction, maintenance and utility work zones. These problem statements were developed from (1) data collected during 103 site visits, (2) an analysis of 30 construction zones before and during accident case studies, (3) a literature review, and (4) personal experiences of an interdisciplinary, six-person professional staff. Results indicate that approximately two-thirds of the work zone safety problems could be ameliorated if current standards and/or knowledge were properly applied. Results also include data relative to traffic control device use, traffic operation, and accident location in work zones.

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.
