RESEARCH PAYS OFF: INNOVATIVE MANAGEMENT SYSTEM FOR ROCK CUTS: ASSESSING ROADWAY HAZARDS IN NEW HAMPSHIRE

The New Hampshire Department of Transportation initiated its first hazard survey of rock cuts in 1975. Since then, the program has more than doubled in size and includes four different rock fall hazard ratings. The program has developed a geographic information system (GIS) to track and centralize statewide rock cut data, assess roadway hazard risk from rock falls, and prioritize rock cut projects according to risk-reduction and cost-benefit scenarios. The analytical capabilities of the system assist in informed decision making on funding safety improvement projects. This article provides further details on New Hampshire's GIS, including applications and benefits.
