TRR no. 1993 includes 22 papers that explore revenue risk mitigation in transportation project financing, traffic sign asset management, estimating highway investment requirements, estimating design hourly volumes, traffic prediction, digital dashboards, random count site selection, wireless location technology-based traffic monitoring, traffic flow impact on travel time variability, and transferability of National Household Travel Survey data. This issue of the TRR also examines the impact of nonresponse and weighting in a travel survey, data integration impact on travel behavior indicators, iterative proportional fitting algorithm for combining traffic count data with missing dimensions, an electronic freight theft management system using Internet-based mapping, and regional routing model for strategic waterway analysis. It also reviews the Highway Capacity Manual adjustment factor for annual weekday to annual average daily traffic, automated consensus-based data verification, enhancing truck data accuracy using dual-loop event data, video-based vehicle detection and classification system, gross vehicle weight distributions from weigh-in-motion data, detection and tracking of vehicle base fronts for traffic counts and speeds, and customizing quality assessment techniques for traffic data archives.

This synthesis will be of interest to highway department administrators, accident records personnel, information systems and data processing management personnel, highway traffic and safety engineers, drivers' licensing officials, state and local police, as well as federal agencies, industries, traffic safety associations, and others responsible for the collection, analysis, and use of accident data. Information is provided on national accident data banks in addition to state and local practice associated with accident data collection, analysis, and evaluation. This synthesis describes current practice with respect to the characteristics and importance of accident data quality, including the reporting and data collection procedures, the analysis and quality control measures employed, and the communications systems used. This report of the Transportation Research Board discusses accident records systems, including data sources and users, considers the effects of inadequate data on analyses, and reviews data acquisition and processing programs that have had good results in the states using them. Recommendations for improving operating systems and for additional research are included.

This updated edition of Traffic Records Program Assessment Advisory gives States information on the contents, capabilities, and data quality of an effective traffic records system by describing an ideal system that supports high-quality decisions and leads to cost-effective improvements in highway and traffic safety. In addition, the updated Advisory outlines a comprehensive approach for assessing the systems and processes that govern the collection, management, and analysis of traffic records data. The Advisory now provides a uniform set of questions derived from the ideal system as described above. The questions are used by a group of qualified independent assessors to determine how close a State's capabilities come to the described ideal. There are three gradations: (a) meets the description of the ideal traffic records system, (b) partially meets the ideal description, and (c) does not meet the ideal description. The Advisory also provides State respondents with standards of evidence that identify the specific information necessary to answer each assessment question. This assessment instrument highlights a State traffic records system's strengths as well as opportunities for improvement.

Traffic crashes kill or injure millions of people each year. High-quality traffic safety data is vital to allocate resources and target programs as the National Highway Traffic Safety Admin, (NHTSA) and states work to improve traffic safety through data-driven approaches. To qualify for federal funding, states must submit plans which include fatality and crash data analyses to identify areas for improvement. This report provides information on: (1) the extent to which state traffic safety data systems meet NHTSA performance measures for assessing the quality of data systems; and (2) progress states have made in improving traffic safety data systems, and related challenges. Includes recommendations. Charts and tables.
