| 摘要： | This paper addresses the Weather Response component of the Infostructure. Its primary purpose is to discuss the fundamental data needs of the weather Infostructure component, and to estimate an aggregate cost for national deployment of road weather data collection systems. It does this by first documenting a methodology for determining the number of Road Weather Information System (RWIS) sensors (sometimes called environmental sensing stations, or ESS) needed across the country to support basic road weather needs, and then documenting a methodology for determining the cost. The paper does not address the information systems needed to convert the sensor data into timely, accurate, and relevant road weather information for specific users. It is also important to note that RWIS represents only one method of collecting information on weather and roadway conditions; it is important that transportation agencies have a wide range of sources available. The national focus of the Infostructure covers the following areas: Metropolitan areas with populations greater than one million; Critical military routes and infrastructure; Critical evacuation routes; and Rural and statewide coverage. This paper concentrates on metropolitan areas with populations greater than one million, of which there are 61 according to the latest census information. |
