Book Description
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.

Book Description
The work zone accident data process is a data collection and processing procedure which starts at the construction and maintenance work site and transmits information through the regular communications channels to the state highway agency headquarters. The process is a supplement to regular police accident reporting and is used to provide a supplement to regular police accident reporting as well as long range summaries (statewide application).

Book Description
This booklet is intended to be a single information resource for currently available Technology Transfer (T2) products on the subjects of traffic control and safety in highway construction and maintenance zones. This booklet is of particular value to state and local highway engineers who are responsible for planning, managing, implementing and inspecting traffic control devices in work and maintenance zones, as well as to individuals who are in need of, or provide, continuing training on all aspects of work-zone traffic management. For each product listed, the address and telephone number of contact agencies are provided along with a brief description and the terms for acquisition.

Book Description
Work zone crashes and fatalities have been decreasing since 1994. Yet, according to Fatality Analysis Reporting System, 667 people were killed in highway work zone crashes in 2009. As the United States' infrastructure ages and new roads and highways are constructed less frequently, the need for repairs and alterations to the nation's roadways is continually increasing. This growth ensures that work zones will be a vital piece of design focus in the near future. In order to continue the decreasing trend in work zone crashes, and reduce the still significant number of work zone fatalities, work zones need to continually be examined to identify opportunities for improved safety. This research explored the relationship between work zone related crashes and work zone design and setup. More specifically, existing literature and current standards, compiled with crash report form data in the UMass Safety Data Warehouse and field observations in Massachusetts were integrated to determine the causes and remedies for work zone related crashes. The research examined three critical areas: 1) causation of work zone related crashes in contrast to non-work zone related crashes along with variations of citations as a result of work zone crashes; 2) variations of the work zone definition and the impact on work zone involvement; and 3) analysis of conflict and event studies for small scale work zones to develop a methodology using surrogate measures to identify potential countermeasures leading to improved work zone safety. The results are expected to advance the current state of knowledge with regards to work zone design and setup, resulting in recommended actions for improved work zone analysis and design strategies.

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
ABSTRACT: Roadway construction has become a common fixture in our daily travels. According to the Federal Highway Administration (FHWA), fatalities in highway work zones were up nearly 50% between 1997 and 2003. In 2003 alone, there were 41,000 injuries and 1,028 fatalities in these locations. Increasingly, safety interests are searching for characteristics associated with work zones that contribute to the dangers of such areas. Like many aspects of traffic safety, a better understanding of the contributing factors in crashes can potentially lead to improved countermeasures. Examining crash data is a principal method by which engineers, police, and safety advocates attempt to determine those factors, but such data are often incomplete. The prospect of improving the data set requires examining the potential of a supplemental data collection system. Using qualitative research, work zone stakeholders potentially provide a better understanding of work zone incidents, rendering new data elements. Creating a web-based supplemental collection system can assist police in gathering the data while completing the current traffic crash report. Supplemental data elements and collection systems have the potential to enrich the data set, and bolster the cause of safety.

Book Description
This report presents the results of a study of reported crashes that occurred in selected work zones from four participating States: California, Maryland, Minnesota, and Washington. Candidate construction projects were identified by the State Transportation Agencies. Data on the location of the project, the start and end dates, the type of project, the type of highway, and other factors were compiled for each project. In addition, data on the work zone was also gathered. Crashes reported when the work zone was in effect and for the corresponding period before the construction project were identified and crash data were obtained. Analyses were undertaken to determine differences in crash rates during construction compared to before construction. The relative increase in rates was on the order of 25 to 50 percent for many of the projects and as much as 100 percent for some of the projects. In addition, an assessment of data elements for work zones and work zone crashes was conducted. Recommendations on a standardized definition for work zones and work zone crashes are proposed.
