Book Description
This synthesis report will be of interest to pavement design, construction, management, and research engineers, highway safety officials, and others concerned with pavement friction characteristics. It describes the current state of the practice and discusses the methods used for evaluating wet pavement friction characteristics of new and restored pavements. This synthesis reviews models used for measuring and evaluating friction and texture, causes for friction changes over time, and aggregate and mix design to provide adequate friction. Also presented are construction and surface restoration practices for providing good pavement surface characteristics. In addition, considerations of noise and ride quality are discussed when compromise may be required.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 352: Value Engineering Applications in Transportation examines the current value engineering (VE) practices of highway transportation agencies in the United States and Canada. Value engineering (VE) is the systematic review of a project, product, or process to improve performance, quality, and/or life-cycle cost by an independent multidisciplinary team of specialists. The report identifies the reported best practices, key strengths, and challenges of current VE study processes and agency programs, and offers guidance on applying and improving the effectiveness of VE in projects and programs.

Book Description
This synthesis documents information regarding the current state of practice for work zone speed management. The report compiles data, procedures, techniques, and technical issues related to observing and comparing work zone speeds. The speed management measures have been organized into four categories: engineering, operational, enforcement, and public education and outreach. Information included in this study was acquired through a review of the literature, two surveys of state department of transportation representatives in all states, a compilation of state agency public information campaigns, and follow-up interviews with select survey respondents from several U.S. states and one Canadian province.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 350: Crash Records Systems examines crash records systems practices and programs as applied to highway and traffic safety. The report covers crash data collection, crash processing and management, and data linkages for reporting and analysis. While no single comprehensive system examples are identified in the report, many examples of one or more successful components were found to address the needs of three groups of stakeholders--data collectors, data managers, and data users. The report also contains information about lessons learned from examples of successful systems, addressing the needs and concerns of stakeholders.
