Reported case studies have verified the advantages of RWIS
. The North Dakota DOT saved between $10,000 and $15,000 in four storms by cutting back on the use of sand on one bridge.
technology, pavement and meteorological sensors and weather data from various sources provide information about the pavement temperature and surface condition.
Part of that mission is to figure out ways to stop RWIs
It relies on the rapid transmittal of data from RWIS
installations, radar, patrols, and any other information source for making a judgment of the probable weather and pavement condition/temperature over the next hour or two.
To help highway agencies adopt these technologies, SHRP also developed guidelines on purchasing, installing, and using RWIS
, and on implementing anti-icing strategies.
stations were originally intended to improve the coordination of weather conditions and CDOT winter maintenance operations; however, this system later evolved to become an integral part of the RITS network.
It is important that roadway and weather conditions, weather forecast updates, and RWIS
data be closely monitored once the initial anti-icing operation has taken place.
spread through spa use are typically skin and respiratory infections in contrast to gastrointestinal illnesses commonly associated with full-body recreational activities found in swimming pools.
This exposure increases the potential for the spread of recreational water illnesses (RWIs
) (e.g., cryptosporidiosis, giardiasis, and shigellosis).
The Texas Transportation Institute (TTI) analysis concentrated on assessing the benefits versus costs of implementing an anti-icing strategy employing a road weather information system (RWIS
