Presentation Outline • • • 2 What is VII? Why Deploy VII? Who is Involved? What’s possible? What are the Challenges?
What Is VII? • Creating an “Enabling Communication Infrastructure” to support vehicle-to-vehicle And Vehicle-to-Infrastructure Communications Supporting Safety AND Mobility Applications 3
Key Communications Technology • FCC has allocated 75 MHz for – Safety Applications (1 st priority) – Mobility Applications – Private Applications • DSRC/WAVE 802. 11 p Standards Complete – – 4 Based on variation of Wi. Fi -- 802. 11 a Low Latency/fast connecting/priority attributes FCC has ruled on licensing – Dec. ’ 03 Testing new devices in 2005
End User Driver HMI Vehicle Data On Board Unit 5. 9 DSRC Road Side Unit 5 Subscriber Applications Message Switch
Objective of the VII Initiative • To determine if the investment necessary to equip new vehicles and the roadway infrastructure with communications are warranted and can be synchronized. A Coordinated Investment • Auto Companies Install DSRC & GPS in all New Vehicles • Public Sector Installs Communications on Roadway Infrastructure Nationwide 6
How We Got Here • The confluence of three activities have presented an opportunity – Growing emphasis on crash avoidance (Safety) and system management and operations (mobility) – Advancements under the ITS vehicle safety program (Intelligent Vehicle Initiative) – Evolution of communications technology 7

Improving Reliability Through System Management and Operations Poor Signal Timing 5% Special Events 5% Bad Weather 15% Bottlenecks 40% Work Zones 10% Traffic Incidents 25% 9 System-wide Real-time Information is the Key!
Weather Response (Snow, Ice, Fog) • 17% of all highway fatalities occur during adverse weather • Existing national weather information is inadequate for highway operations • Efforts to enhance this information locally are expensive and of limited value • Sensors on vehicles could provide continuous data on air and road surface temperature, visibility, precipitation, etc. 10
VII Impact on Overcoming Surface Transportation Weather Gaps • Three fundamental deficiencies today – Lack of transportation system relevant weather observations – Lack of understanding on how to apply weather information in decision making – Lack of capabilities for predicting and/or assessing surface level weather phenomena • VII opens the opportunity for empirical data gathering not possible otherwise 11
VII Impact on Weather-related Decision Making • VII enables enhanced response and planning through improvements to weather observations, models, and predictions – Microscale events for immediate response (e. g. , black ice, fog banks) conveyed in seconds to minutes – Mesoscale events for tactical response (e. g. , thunderstorms, flash floods) forecast in minutes to hours – Synoptic scale events for strategic response (e. g. blizzards, floods, heat) forecast in hours to days 12
