This research project developed and demonstrated a cost-effective system for evaluating and prioritizing highway rockfall hazards state-wide. The project was designed to produce a method for evaluating large segments of the highway system without getting bogged down with minor maintenance or rare rockfall issues.

The prototype system consisted of three parts: 1) a computer-sorted set of data bases, including past highway rockfall accidents since 1976; 2) a ride-through program with maintenance patrol personnel, and 3) a system for categorizing and ranking individual highway rockfall hazard sites. The study demonstrated that data developed and collected by this three-part approach can be used to direct the Colorado Department of Transportation (CDOT) to those sites having the highest rockfall hazard.
