1	Clarus Use Case 5: Enhanced Road Weather for Traveler Advisories Chris Cluett
2	Functionality of the Tool Forecasts of pavement conditions up to 12 hours out Restricted to Interstates Integration of atmospheric conditions and road surface conditions, with presentation in looped view Multi-state view
3	What We Evaluated State DOTs’ perceptions of usefulness of the tool State DOTs’ interest in making further investments in the tool Travelers’ perceptions of the tool’s informational value Users’ perception of enhancement to safety and mobility Drivers’ decisions to adjust travel plans and behaviors in response to weather Value to long distance and cross-state travelers of the new information provided consistently across state boundaries
4	Evaluation Approach Two focus groups in SD in early summer 2010 with general and commercial travelers regarding reactions to experimental website and 511 Web surveys in ID, MT and ND Jan-Feb 2011 with 216 traveler information users to assess value/benefits/uses of new pavement condition forecasts Interviews with state DOT operators to assess how they used the tool in practice
5	Results Summary Focus Group Findings Users say they value pavement condition forecasts Users want demonstrated real-time accurate information on Wx Visual images preferred; travelers like the radar loop (trend) forecast Information on road closures critical; if road open, will go regardless CVOs desire 12-24 hr advance Wx information for planning Uniformity of information across states is important to CVOs Would like ability to toggle through simplified, layered information
6	Results Summary Web survey results (216 responses) 58% visited website 10+ times in prior 30 days Number times used road weather information to change travel in prior 30 days?
7	Results Summary Type of trip you are planning with this website visit?

13	Panel Discussion: Multi-State / Multi-Jurisdiction Road Weather Information Vision of success, focusing on road weather Where are we now? Where would we like to be in 5-10 years?
14	Panel Discussion: Continued What needs to happen to get there? Strategies for engaging stakeholders (state DOTs; vendors; travelers; others) Road weather data & information requirements for multi-state travel Effective dissemination methods & formats to present the information (need for standards?) By corridor By region National Costs/funding Other gaps & challenges?
