"TRB Special Report 292 ... recommends the creation of an independent scientific advisory committee (SAC). The SAC would be charged with development of a transparent process for identifying and prioritizing research needs and opportunities in highway safety, with emphasis on infrastructure and operations, and using the process developed to recommend a national research agenda focused on highway infrastructure and operations safety. The report also explores opportunities to improve the quality of highway safety research." -- publisher's website.
"TRB's National Cooperative Highway Research Program (NCHRP) 756: Highway Safety Research Agenda: Infrastructure and Operations develops a proposed agenda of prioritized safety research needs in the area of highway infrastructure and operations. The report provides options to the U.S. transportation community on how to direct research to the areas where it can provide the most benefit. The agenda is based on a prioritization methodology developed by the research team which can be applied on a recurring basis to update the agenda over time. Both the agenda and the methodology documented in this report will assist government officials, private sector employees, and academics with managing highway safety research. In addition to the report, 16 unpublished appendices (Appendices A-O and R) have been made available electronically."--Publisher description.

Asset management is a strategic approach to the optimal allocation of resources for the management, operation, maintenance, and preservation of transportation infrastructure. Asset management combines engineering and economic principles with sound business practices to support decision making at the strategic, network, and project levels. One of the key aspects of the development of asset management is data collection. The way in which transportation agencies collect, store, and analyze data has evolved along with advances in technology, such as mobile computing (e.g., laptops, tablets), sensing (e.g., laser and digital cameras), and spatial technologies (e.g., global positioning systems [GPS], geographic information systems [GIS], and spatially enabled database management systems). These technologies have enhanced the data collection and integration procedures necessary to support the comprehensive analyses and evaluation processes needed for asset management. Data collection is costly. In determining what data to collect, agencies must weigh these costs against the potential benefits from better data. Traditional pavement and bridge management approaches are data intensive, requiring extensive data collection activities of most or all pavement and bridge assets on an annual or biannual basis. These efforts can be justified given the cost of agencies’ pavement and bridge programs. However, depending on the level of technology needed and the associated costs, it may be difficult to justify similarly extensive data collection efforts for safety and operation assets. While many of the technology innovations and improved data collection processes have been in the bridges and pavements area, there are emerging technologies in the safety and operations infrastructure areas that have yet to be applied to the transportation space. These technologies are driving the costs and efficiencies to the point that makes good sense in terms of the tradeoffs between fiscal responsibilities and advantages of having the data. Therefore, while this research covers all highway infrastructure areas, it includes an emphasis on technologies to assess safety and operations infrastructure. Ultimately, through the three-phased approach, the research strives to bundle the best technologies that maximize sensors and computing power in an effort to achieve the vision of one day having an all-in-one data collection system for infrastructure assessment.
Highway Safety Analytics and Modeling comprehensively covers the key elements needed to make effective transportation engineering and policy decisions based on highway safety data analysis in a single. reference. The book includes all aspects of the decision-making process, from collecting and assembling data to developing models and evaluating analysis results. It discusses the challenges of working with crash and naturalistic data, identifies problems and proposes well-researched methods to solve them. Finally, the book examines the nuances associated with safety data analysis and shows how to best use the information to develop countermeasures, policies, and programs to reduce the frequency and severity of traffic crashes. Complements the Highway Safety Manual by the American Association of State Highway and Transportation Officials Provides examples and case studies for most models and methods Includes learning aids such as online data, examples and solutions to problems
