- 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***

## Key Communications Technology

- FCC has allocated 75MHz for
- Safety Applications (1st priority)
- Mobility Applications
- Private Applications
- DSRC/WAVE 802.11p Standards Complete
- Based on variation of WiFi --  802.11a
- Low Latency/fast connecting/priority attributes
- FCC has ruled on licensing – Dec. ’03
- Testing new devices in 2005

## 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**

## 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

## Driving Forces: Safety

***We have the***
***opportunity ******to change ******the trend!***

## Improving Reliability Through System Management and Operations

**Bottlenecks**

**40%**

**Work Zones**

**10%**

**Bad Weather**

**15%**

**Traffic **

**Incidents**

**25%**

**Poor Signal **

**Timing**

**5%**

**Special **

**Events**

**5%**

**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.

**Notes:**
How about getting rid of the inset picture of the tree. Then the snowy road can be bigger.

## 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

## 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

## Preliminary Conclusions

- VII Working Group has concluded that VII is technically feasible
- Priority Applications - benefits
- Requirements Defined
- Architecture Complete
- Multiple Communication Options

## We have work yet to do

- Application Development
- Privacy
- Data ownership
- Liability
- Deployment approach
- Business approach
