What Is Clarus?

Clarus (which is Latin for "clear") is an initiative to develop and demonstrate an integrated pocket option download for windows observing, forecasting and data management system, and to establish a partnership to create a Nationwide Surface Transportation Weather Observing and Forecasting System. The objective of Clarus is to provide information to all transportation managers and users to alleviate the effects of adverse weather (e.g., fatalities, injuries and delays).

NEW! U.S. DOT’s Federal Highway Administration Releases Request For Proposals for Clarus Initiative

The Federal Highway Administration has posted the Request for Proposals for Phase 3 of the Clarus Regional Demonstration on the FedBizOpps website. 

The objective of this contract is to show how quality-checked road weather observations from the Clarus System are utilized by, or a benefit to, the public and the public agencies responsible for transportation system operations.  This will be achieved through the development and deployment of Clarus-enabled services (e.g., enhanced road weather information and related decision support tools) which build upon use case scenarios provided within the Phase htts://  In addition to the development and implementation activities, the contractor(s) will be expected to document their experiences in using the Clarus System.

For more information regarding the Request For Proposals, contact Charles D. Kotch via email or at 202-366-6622.
