What VII will Enable …. Safety


Imagine:
• Your vehicle knows the
  speed and location of
  approaching vehicles
• Your vehicle can “see”
  vehicles you can’t see
• Your vehicle knows
  roadway conditions that
  you can’t see
What VII will Enable….. Mobility


Imagine:
• You had traffic information on
  all your potential routes and
  modes of travel
• You could compare different
  routes and modes of travel
  based on traffic speed
• Your navigation unit could
  reroute you when an accident
  occurs during travel
 What VII will Enable …. Consumer Services

Imagine:
• You can quickly download movies
  and other high content material
  into your vehicle
• You can find and reserve available
  parking spaces before you arrive
• You can pay for tolls, parking, and
  your morning cup of coffee
  automatically from within your
  vehicle
• Your vehicle can tell you when it
  needs servicing and direct you to a
  service station
What VII will Enable …. Agency Management &
Operations

Imagine:
• Managing your system if you
  knew real-time travel speeds
  and densities, braking activities,
  and roadway temperatures for
  all major facilities
• Planning for growth when you
  know complete traffic patterns
  around development
• Having the information needed
  to measure and track system
  performance

USDOT’s Research and Demonstration Program
A Change in Strategy

• Previous approach
  – Deployment decision by OEMs, US DOT, state transportations agencies
    in 2010 with synchronized deployments beginning around 2012
  – Key technology for vehicle to infrastructure communications was
    Dedicated Short Range Communications (DSRC)
  – Expectation that the infrastructure build out could be substantially funded
    by the Federal government
• Current approach
  – Open up the architecture to allow for non-DSRC technology
  – Work with aftermarket suppliers to enable VII capabilities sooner
  – Demonstrate a subset of capabilities that VII can provide in a few, high
    concentration operational test sites
  – Support growth in geographic coverage and functionality over time
  – Leverage new technologies and private industry developments
  – Learn from related state and university research
Program Goals and Objectives


• Goals
  – Nationwide system
  – Enable the full range of safety, mobility, and commercial
    applications
  – Adaptable to technology evolution
• Objectives:
  – Near term – to demonstrate current capability and provide for
    more rapid deployment of VII applications
  – Mid term – to expand both the system functionality and
    geographic coverage of the system
  – Long term – to enhance system performance
Multi-Phased Approach


• Phase 1 – Field operational test site(s) established to
  demonstrate and test what can be done today
• Phase 2 – Applied research and development activities to
  support the longer term needs of the program in areas of
  technology, policy, and public agency applications
• Phase 3 – Monitoring and assessing new technologies that
  can enhance system performance
Phase 1: SAFE TRIP-21
Safe and Efficient Travel Through Innovation and Partnerships

Develop field test bed(s) to:
– Accelerate availability of travel information and services to
  provide users with greater situational awareness of safety hazards,
  congestion bottlenecks, and route and modal choices
– Evaluate impacts, value of integrated infrastructure for travelers
  and commercial operators, and market readiness of near-term
  applications, including but not limited to those using DSRC
– Leverage other U.S. DOT activities such as the Urban Partnership
  Agreements, the Corridors of the Future Sites, and others.
– Leverage existing systems and capabilities (i.e., 511, Highway
  Advisory radio, vehicle-based collision warning technologies, traffic
  reporting services, etc., and state, local, university, and industry
  research )
Phase 1: SAFE TRIP-21 (2007 – 2008)

Key Dates and Milestones

 Request for Information (RFI) released December 18, 2007
   Information requested on partnering for Phase 1 test site development
   Information requested on test site characteristics, applications and their
    readiness, innovative technologies
 RFI responses expected by January 11, 2008
 Site(s) operational and evaluation to begin December 1, 2008
 Interim findings will be transitioned toward mid- and longer-term
  ongoing research in VII Phases 2 and 3
 SAFE TRIP-21 Final Report in January 2010 (Interim reports in 09)
Phase 2 – Enable a Phased Nationwide Deployment

• Fund applied research and development activities:
   – In the areas of enabling technologies, public applications, and
     institutional issues
   – To support a phased, nationwide deployment of VII capabilities
     between 2008 and 2015
• Key Objectives:
   – Assess and demonstrate capabilities of various technical solutions
   – Identify phased roll-out strategies to support rapid deployment of
     near-term capabilities and enable the long term vision
   – Analyze alternative business models and governance structures
   – Develop technical and policy solutions to address security, privacy,
     liability and other institutional issues
   – Develop key applications for the public sector
   – Leverage results of operational tests and state and university
     research to improve and refine research and deployment approaches
VII National System Network Build Up
 Phase 2 – Enable a Phased Nationwide Deployment
    Proof of Concept (POC) Testing – MI and CA
• Testing of public, private, and e-commerce applications
   – Testing to be completed in March with results published in June 2008
• Validate the vehicle to roadside and vehicle to vehicle capabilities in a multi-
  application environment
• Demonstrate that VII technical approach ensures anonymity, privacy, and
  security
• The Michigan POC test includes:
   – 25 vehicles, 57 intersection and freeway locations near Detroit 
      approximately 47 square miles of coverage
   – Vehicle based communications is DSRC for both V2I and V2V
   – Backhaul communications is a combination of 3G, WiMax, and Mesh
• Scheduled to operate through June ’08
• Currently preparing an RFI to solicit input and expressions of interest in:
   – Using the test bed by other private and public sector entities and
   – Options for continued operation and maintenance
Most of the VII POC Testing will be conducted in the suburbs of
Detroit. RSEs placed along several stretches of highway as well as
multiple signalized intersections.
