Information systems for road management: draft guidelines on system design and data issues; technical paper
William D O Paterson, T Scullion · 1990
This is a draft portion of guidelines for international use on the development of information systems to serve all road management applications in the highway sector. It provides an objective reference to help agencies make appropriate choices about the information needed for decision making and how to collect and manage it. A generic modular framework is used to make the system flexible, relevant to the diverse needs of different levels of management, appropriate to the size, skills and resources of different agencies, and able to accommodate upgrading in response to future changes in technology or circumstances, Nine groups of information and four levels of information quality (IQL) from basic to comprehensive are defined. For each group and quality level, specific data items are identified in a consistent manner so that higher levels of detail can be condensed and transformed into the summary or basic level. Data collection methods for each information group are synthesized indicating the modes of measurement applicable, the methods and equipment available for each mode, and the approaches to frequency, sampling and coverage for the collection of each data item.
