Bridge inspection standards in the United States require routine visual inspections to be conducted on most bridges at a maximum interval of two years regardless bridge condition. Limitations this uniform calendar-based approach have been reported literature. Accordingly, objective study is provide new systematic for planning that integrates information from condition prediction models, data, a...

To meet policy requirements on increased transport energy efficiency and reduced emissions, smart control and management of vehicles and fleets have become important for the development of eco-friendly intelligent transportation systems (ITS). The emergence of new information and communication technologies and their applications, particularly vehicleto-vehicle and vehicle-to-infrastructure comm...

Surface terrain information is required to economically site new or relocate existing infrastructure facilities and make final design plans. Currently, field surveying and photogrammetric mapping are the most widely used methods to acquire these data. However, these methods are time and resource intensive as significant data collection and reduction is required to provide the level of detail ne...

IN T R O D U C T IO N Population forecasters have estimated that the 1970 census when reported will show close to 75 percent of the United States popula­ tion will be classified as urban. Once again one can expect that the greatest percentage change will occur in the urban fringes of central cities of population range of 25,000 to 100,000. Along with the in­ creased population growth and disper...

This paper briefly describes a model, designed to automate data acquisition and analysis for planning and scheduling highway construction projects. The paper briefly describes the proposed model, and focuses primarily on its automation aspects. Geographic information systems is employed to analyze spatial data and estimate cut and fill quantities. The model also stores activities typically invo...

In a fully automated Automated Highway System (AHS), the roadside control system and the vehicles themselves are responsible for moving the large number of vehicles safely and efficiently. Therefore, the task of operating an AHS is drastically different from and much more complex than its conventional counterpart. Resulting from a large number of design options, there exist many possible ways t...

Highway Interchange projects present particularly complex and changing geometric configurations. Such configurations are hard to visualize and understand, and associated management, construction decisions, and traffic control strategies are difficult to optimize and communicate. This paper presents a computerbased system, which utilizes 3D and 4D CAD technology in order to: facilitate the commu...
