An Integrated Information System for Highway Asset Management

摘要: The University of Arkansas has engaged in developing a digital highway data vehicle the past few years. A primarily goal for this research was to provide industry new platform collect and analyze roadway pavement condition data. Condition related analysis on existing roadside structure are important department decision making process asset management rehabilitation, improvement road geometric re-alignment study, traffic studies. decision-making relies availability accurate adequate through use collection devices information systems. paper presents technologies used vehicle, including vision imaging, high performance sensors, Global Positioning System (GPS), microcomputers, automated storage processing components. design implementation multi-function presented. benefits using discussed. An approach is revealed application an integrated system managing pavements (MMHIS). Particularly, advancements survey distresses This achieves real-time complete surfaces at network level, images which collected archived high-resolution format. Finally, three distress protocols demonstrated with system.
