Landslide can be a factor causing damage to roadways and imposing safety hazards to the traveling public. Thus, developing an effective landslide hazard management system can be an important responsibility for a highway agency. This paper presents rationales for the need of developing an effective landslide hazard management system for roadways, demonstrates and argues for the essential ingredients for such a system, uses Ohio Department of Transportation (DOT) landslide hazard management system as a prototype to illustrate the development and validation process, and describes in some detail of the Ohio DOT system with emphasis on the inventory process, inventory data fields, and hazard rating matrix and scoring methodology. A concluding remark was made for advocating multi-disciplinary approach and integration of geographic information systems (GIS) platform, relational database, and internet connectivity for an effective landslide hazard management system.
