Title:

1999-2000 Techology and Usage Survey Results: Anti-icing Techniques and Road Weather Information System Technologies

Abstract:

In order to measure the transfer of Anti-icing/RWIS technology, two surveys were conducted. The first survey was conducted in 1997 to establish a baseline report to determine the current use of the technology and to establish a comparison point. In 1999, a second survey was conducted. This report presents the results from the second survey in 1999. In 1999, 260 out of 517 surveys were returned. Survey results indicate that nearly 90 percent of responding states reported using anti-icing strategies, sodium chloride and magnesium chloride were the two chemicals used most often, experience with anti-icing techniques is growing, a majority of states reported using RWIS, and over half the states reported transmitting road information to the public with the internet being the most prevalent method.
