The Clear Roads pooled fund project began in early 2004 in response to a need for real-world testing in the field of winter highway operations. This ongoing research program has already attracted 26 member states and is funding practical, usable winter maintenance research. Wisconsin DOT led this pooled fund from 2004 to 2009 under TPF-5(092). The Minnesota DOT now leads the project under TPF-5(218).
Sensors and other electronic devices used on winter maintenance vehicles are often provided by different vendors, each with its own proprietary communication protocols and data formats. To give DOTs more flexibility and reduce the costs of integrating new components, Clear Roads is working with the vendor community to develop a standard protocol that will allow plug-and-play connectivity for devices from different vendors.
Clear Roads has drafted a specification for a standard communications protocol, and is inviting all interested stakeholders in the winter maintenance community and related vendor organizations to provide comments and feedback.
For more information on the background of this collaborative effort and the development of the protocol, we have provided the informative webinar below.
The draft protocol specification is available here. Comments can be sent to firstname.lastname@example.org until February 28, 2014. All comments along with Clear Roads’ responses will be posted on the website after the comment period has ended.
Clear Roads has developed a web-based toolkit that takes the guesswork out of evaluating winter maintenance investments. It facilitates cost-benefit analysis for 21 different winter maintenance materials, equipment and methods. There is also a User's Manual and training videos to help you get started.

A new webinar provides an early look at the results of a Clear Roads research project that sought to better understand the true costs for snow and ice removal. In this 65-minute presentation, project researcher Andrew Cadmus of Parsons Brinkerhoff outlines the study’s findings and answers questions from the Clear Roads project panel.
The Final Report, an Estimation Tool, and a Research Brief on the project are anticipated soon. Click here for more details on the project.
Clear Roads has completed a research project that evaluated and ranked the toxicity of several deicing chemicals. The Final Report, a 2-Page Summary and a Video of the final presentation webinar are all available here.
In this quarterly e-newsletter, you'll find summaries and links to the latest technical news and best practices from the U.S. and around the world, highlighting applications of winter maintenance research and technology and the latest transportation research by state DOTs, universities, TRB and FHWA.
March 25-27, 2014
Clear Roads will meet to discuss and rank research projects for 2014 funding and get updates on research in progress.
