Long-Term Pavement Performance (LTPP) Program in Japan
Japan's `Manual for Design and Construction of Asphalt Pavement' is based on technical results from the AASHO Road Test in 1960's. Strategic Highway Research Program (SHRP) is a much bigger...

Condition Data Reduction for Pavement Management
A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should...

Traffic Accident Analysis System
While statistical data on traffic accidents are invaluable in devising effective traffic safety measures, the number of data items and samples are vast and they must be processed and edited...

Issues in GIS-Based Subsurface Data Management
Obstacles and barriers preclude an interagency GIS application for managing spatially-related subsurface data. Such a system would enable geotechnical and earthquake engineers from state...
