1. VII Day-1 Applications and MDSS Pat Kennedy Road Weather Management Program Federal Highway Administration Maintenance Decision Support System (MDSS) Annual Stakeholders Meeting August 11, 2006

2. 2 VII VII (Vehicle Infrastructure Integration) is a USDOT/FHWA sponsored initiative aimed at developing and deploying a nationwide integrated communications infrastructure that supports both vehicle-to-vehicle and vehicle-to-infrastructure communications Development of Day-1 applications will be used to help define and refine what this network will look like on the first day it becomes operational

3. 3 Application development Twenty “Day-1” applications have been selected for development by members of the VII Working Group and a variety of other Subject Matter Experts. Application selections were based on a number of factors: –Meeting high priority safety, mobility, and commerce needs –Need to be achievable within acceptable timeframes –Provide some early benefit to users and operators –Achievable with low penetration of VII-equipped vehicles –Providing the ability to test the system and assist the decision making process

5. 5 Day-1 application #16: Winter Maintenance PURPOSE: Provide additional environmental and surface condition information to the management functions responsible for winter maintenance on our nation’s roadways GOALS: Collect environmental data from multiple vehicle sensors Process this data into MDSS, thereby: –Improving real-time surface condition information provided to transportation operators and managers –Improving the accuracy of predictive forecasts for route specific surface conditions and associated treatment recommendations
