Abstract:Fog is a common and recurrent phenomenon in West Virginia which is the cause of nearly 1.3% of all fatal crashes occurring all over the state. All three types of fog are common in the state which results in lack visibility, limited contrast, distorted perception, judgment errors, and reduction in headway and speed of the vehicle traveling in foggy conditions. State of West Virginia is suffering from lack of suitable fog detection and warning system along many of its arterials where fog is a major issue. The purpose of this project is to first determine favorable fog condition in terms of different meteorological components and introducing various forecasting tools which are utilized by different agencies in fog forecasting process. In addition, it has been tried to identify the critical fog prone areas across the state. These places might serve as the potential location for implementation of fog detection and warning systems. Also, a complete description of the available detection and warning system which are currently active across the country has been presented in this report to provide useful insight regarding these system's capabilities and effectiveness. Finally, through a simple benefit cost analysis justification efficiency of fog detection and warning system is demonstrated.
