Road Weather Information System Environmental Sensor Station Siting Guidelines;Final rept. Nov 03-Jan 05

摘要

A Road Weather Information System (RWIS) consists of the hardware, software, and communications interfaces necessary to collect and transfer road weather observations from or near the roadway to a display device at the user's location. While the original purpose of RWIS was to address winter weather conditions, applications have been developed to detect and monitor a variety of road weather conditions impacting road operations and maintenance. Most RWISs now consist of several meteorological and pavement condition monitoring stations strategically located near highways to help transportation managers make more informed operational decisions. An Environmental Sensor Station (ESS) is considered the 'collection' component of an RWIS and consists of the equipment and sensors installed within or along a roadway. This document provides guidelines for siting an RWIS ESS and its associated environmental and pavement sensors. These guidelines are intended to help establish uniformity in siting ESSs and to improve the usefulness of road weather information derived from ESS observations.
