Abstract:MORFH RS (Missouri Rock Fall Hazard Rating System) is a new scheme for rating of rock fall hazards along the roads of the Missouri State Highway System. Existing rock fall hazard rating systems used in other States focus on the risk of failure and ignore the consequence of failure, or they lump the ratings for risk and consequence together. In MORFH RS, risk and consequence factors are given equal weight and isolated from each other. The ratings for the categories that relate to risk or consequence are easy to determine and are more objective. The risk – consequence rating system can be used by MODOT (Missouri Department of Transportation) to cost effectively determine the need and priority of remediation, and help facilitate the design of maintenance on rock cuts in order to provide for the safety and convenience of the motoring public by reducing the risk and consequence of falling and fallen rock to life and property.
