Proximity Warning Systems are currently the focus of many research groups. Their goal is to produce a system that will reduce the number of run over incidents that occur in large mobile equipment operations. A majority of these incidents occur when the equipment starts from the In-rest state and begins to move. The addition of a transmission locking mechanism to a GPS based proximity warning system will prevent more run over incidents. This transmission locking mechanism will automatically prevent equipment from moving when there is a high risk for a potential run over incident to occur. Additional safety and optimization for surface equipment can be provided by utilizing GIS software for data analysis just by using the data collected from a GPS based proximity warning system. Combining these ideas and methods can provide better safety for large mobile equipment operations.
