| 摘要 |
A system and apparatus for detecting and evaluating surface conditions on a road surface and atmospheric conditions simultaneously from a vehicle is disclosed. The system comprises a sensor for detecting the presence of deposited material on a road surface, a detector for determining one or more characteristics of the deposited material such as freezing temperature, process means for converting a detected signal and display means for displaying the condition of the road surface, and a sensor for detecting falling precipitation. An embodiment of the present invention includes a remote sensing apparatus which utilizes electromagnetic radiation to sense actual surface material conditions, temperatures, and composition and local atmospheric conditions at the vehicle as it is moving over a travel surface. This information is then processed through a computer in order to determine those additional steps necessary to apply additional materials to the road surface in order to minimize hazardous driving conditions.
