【国外标准】 Standard Guide for Prioritization of Data Needs for Pavement Management

3.1 A key objective of all pavement management systems (PMS) is to provide a factual basis for improving the quality of decision making regarding the budgeting, design, programming, construction, maintenance, and operation of a pavement network. Quality decision making requires a current inventory of the pavement system, evaluation of the present condition and use of the pavement system, estimation of future condition, and the implications of any changes in condition.3.2 This guide may be used to identify data needs for pavement management by considering the use, generic type, and relative importance of the pavement. It can also assist in identifying methods for obtaining the data.3.3 Any data element selected for collection should have a specific use and be of value in providing information from the PMS for the decision-making process.3.4 The specific type of data needed to make informed pavement management decisions will vary with such factors as the size, complexity, and condition of the pavement network, the levels of service to be provided, the agency budget, and budgeting process. Further, since pavement management is a dynamic process responsive to changes in technology, the data needs for a particular agency may be expected to change over time. Accordingly, judgment invariably will be required in applying this guide to develop a hierarchy of data needs.1.1 This guide identifies data needs for pavement management systems. It also addresses the relative importance of various types of pavement data.1.2 This guide was developed for use by federal, state, and local agencies, as well as consultants who provide services to those agencies.1.3 This guide describes a process and provides a set of recommendations that any agency may use to develop a plan for acquiring pavement management data. Any individual agency may justifiably assign higher or lower priority to specified data items depending on their needs and policy.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
