Clarus Connection Incentive Program


In June 2007, the FHWA released a Request for Applications for the Clarus Connection Incentive Program ( CIP). The CIP provides grants to State transportation agencies to participate in the Clarus regional demonstration. Funding is available to assist in offsetting the cost that enable the State Road Weather Information System (RWIS) Envitomental Sensor Station (ESS) networks to be connected to the Clarus System. Such actions include :

  • Travel-related cost (e.g., mileage, lodging) to reach ESS sites to collect metadata,
  • Cost associated with compiling climate metadata,
  • Cost for equipment used in the aquisition of site metadata,
  • Cost to modify ESS collection server software so that observation files conform to the Clarus interface standard

There are number of important benefits associated with participation in this program, including the oportunities for State transportations agencies to :

  1. Easily monitor the heath of ESS network and optimize network performance through the quality checking service
  2. Gain access to road weather observations from entire Clarus network, and
  3. Benefit from the new tools, techniques and improved forecast enabled through the Clarus system

Applications will be reviewed on a first-come, first-served basis. Decision regarding the acceptance of specific applications for funding will be made within 30 bussiness days of receipt.
