Transportation agencies are developing procedures and guidelines for managing the quality of pavement data collected to ensure the data meet the needs of the pavement management process. This study reviews the quality management practices being employed by public highway agencies for automated, semi-automated, and manual pavement data collection and delivery. Information was gathered through literature review, surveys of U.S. state and Canadian province public agencies and private contractors, and selected interviews.

This fifteenth volume of NCHRP Report 525: "Surface Transportation Security" is a guide referred to as CAPTA, which stands for Costing Asset Protection: An All Hazards Guide for Transportation Agencies. CAPTA supports mainstreaming an integrated, high-level, all-hazards, National Incident Management System (NIMS)-responsive, multimodal, consequence-driven risk management process into transportation agency programs and activities by providing a convenient and robust planning tool for top-down estimation of both capital and operating budget implications of measures intended to reduce risks to locally acceptable levels. CAPTA is intended for use by senior managers whose jurisdiction extends over multiple modes of transportation, multiple asset classes, and many individual assets. The CAPTA methodology provides a means for moving across transportation assets to address system vulnerabilities that could result in significant losses given the threats and hazards of greatest concern. This guide was reviewed by many state and local agencies and was pilot tested by the Maryland Department of Transportation (DOT), the Massachusetts Bay Transportation Authority (MBTA), and the Virginia DOT.

This report updates the findings contained in NCHRP Report 522, "A Review of DOT Compliance with GASB 34 Requirements." NCHRP Report 522 provided a comprehensive look at approaches taken by AASHTO member departments to comply with the requirements of Governmental Accounting Standards Board (GASB) Statement No. 34. NCHRP Report 608 provides a recommended practices guide that identifies effective methodologies that integrate infrastructure inventory, condition assessments, minimum acceptable condition levels, and funding decisions with GASB 34 reporting requirements and assesses the operational and financial impacts of reporting under GASB 34. This report will be helpful to professionals who work with state departments of transportation and local governments in the areas of finance, auditing, asset management, and policymaking.
