This report provides the results of a detailed investigation of environmental sensors and their applicability in highway operations. It describes the functional requirements for a weather condition detection device to be applied to the roadway infrastructure based upon current guidelines of various state and federal agencies. The report also analyzes the results of a year-long series of field tests of visibility sensors. A group of one mobile and five stationary sensors were examined to determine the applicability of the data reported by these devices. Among the areas of focus was the accuracy of the reported visibility to the actual conditions, time to respond to visibility changes, and the robustness of the systems. The results of the test appear to indicate that these devices have definite possibilities for future deployment, particularly in conjunction with ITS technologies.
Three transmissometers and five forward-scatter meters were evaluated for measuring fog, haze, rain and snow in the large test chamber of the Eglin Ai...
