1. FHWA Perspectives on VII Pat Kennedy Road Weather Management Program Federal Highway Administration VII Weather Applications Workshop II June 21, 2006

2. 2 DOT Vision for the VII Initiative The DOT has a vision for the VII initiative that includes achieving nationwide deployment of an integrated communications infrastructure that supports both vehicle-to-vehicle and vehicle- to-infrastructure communications. This network will enable improvements to be made on a broad range of safety and mobility services that are currently unattainable. Safety –Supplying system operators with real-time road weather information that allows them to respond to trouble spots in a quick and efficient manner. Mobility –Providing system users and operators with real-time updates on congestion problems, adverse weather conditions, and incidents.

3. 3 Five Phases of the Initiative Technical –Architecture development Policy –Addressing data ownership and rules Business Models –How the VII system will be deployed, operated and maintained over the long term Outreach –Engaging the stakeholders Application Development –Defining how VII data will be applied –FHWA and other DOT modal agencies working with Subject Matter Experts on these definitions

4. 4 Application Development Twenty “Day-1” Use Cases have been developed and reviewed by members of the VII Working Group and Subject Matter Experts. The Use Cases were selected 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 Priority during this phase has been on developing Use Cases that provide “Day-1” functionality and identifying additional applications

6. 6 Researching the Data Characteristics Examining the capability of VII probe data to support key traffic management use cases (specifically): –Signal control –Freeway and Corridor Management –Weather Information –Traveler Information Objectives: –Identify likely content of collected VII probe messages –Develop algorithms that estimate key measures –Estimate the accuracy of these algorithms under various conditions (scenarios) Near-term analytical emphasis is on the support of Day 1 applications

8. 8 Building and Testing Applications Application Development Plans – June 2007 These plans, which are envisioned to serve as high-level road maps for the development of fully tested, certified, and nationally deployed VII applications at Day-1, will need to address a variety of issues such as: –Identifying the needs for application development and rollout –Identifying fundamental research requirements –Defining, refining, and demonstrating the applications as they are being developed –Identifying roles of US DOT and state/local agencies that facilitate the application development process –Identifying long term needs to assist local transportation agencies in integrating the applications that are developed with their current systems
