"Safety – 32,885 highway deaths..."
  • Safety – 32,885 highway deaths in 2010, 5,400,000 crashes/year
    • Opportunity - Intersection safety, where 7% of fatalities at signalized intersections ($19 billion annual cost) and 14% at non-signalized intersections
    • Run off Road – 40% of fatal crashes
  • Mobility – 4,200,000,000 hours of travel delay, $80,000,000,000 cost of urban congestion
    • Cooperative Adaptive Cruise Control could improve freeway capacity by 50%
    • Reduce delay from signal system management by 25%
    • Improve transit connection success by 90% and reduce wait time to 10 minutes or less
    • Improve incident response by 30%
    • Improve freight delivery travel time (less wait time at terminals and faster freeway travel – 15 to 30%)
  • Weather
    • Improve safety in adverse weather conditions
    • Reduce Public Sector cost in treating facilities
  • Environment  - 2,900,000,000 gallons of wasted fuel
    • Reduce Fuel Use
    • Reduce Emissions

Key Assumptions and Questions
  • Assumption
  • Vehicles have DSRC and penetration rates climb over a 20 year period
  • Cellular based communications to vehicles will continue to evolve (carry-in and built-in products, with opt-in consumer pay services)
  • Connected Vehicle Core System Architecture Guides system evolution.


  • Questions
  • Where is DSRC Infrastructure Communications Necessary?
  • How does the benefits equation for installation of DSRC Infrastructure change as penetration rates for vehicles and infrastructure evolve?
  • How would a cellular based solution occur and provide benefits to the public sector? We are already seeing some.
  • What additional vehicle based data is needed to enable applications that solve problems? Over what portion of a trip is that data needed? When and where is that data needed?
  • What information is necessary to send from the infrastructure to vehicles?

V2I Safety
  • Enable the Critical Infrastructure Technology
    • Communications
    • Positioning
    • Signal Phase and Timing Messaging
    • Developing the Prototype Roadside Equipment


  • Determine Benefits through Applications Development and Testing
    • Red Light Violation Warning
    • Curve Speed Warning
    • Rural Stop Sign Assist
    • Transit Pedestrian
    • Truck  - Smart Roadside

  • Create Implementation Guidance
    • Standards
    • Specifications
  • We are in the middle of the application definition phase and about to enter into application prototyping and testing.

Key Questions for V2I Safety
  • What DSRC-specific apps are most valuable? What are the benefits?
  • How will we cost-effectively obtain absolute positioning?
  • How/when might equipment installation occur? Signal upgrades, targeted intersections, transit enhancements, high accident curves, truck inspection stations?
  • What info do you need to invest in DSRC infrastructure?  Currently, application investment assumes existing local and federal funding sources.
11
Mobility Program Elements
  • Determine Approaches to Capturing and Managing Multi-sourced Data
  • Determine Benefits from Applications
    • Identify and Define Applications
    • Build and Test Prototype Applications
  • Develop Implementation Guidance
    • Policies
    • Standards
    • Specifications


  • We are defining applications in 6 high priority bundles (freeway operations, arterials, incident management, transit, freight, and traveler information) and will move into application development soon.


  • Weather Research has dedicated funding and a similar approach.
  • AERIS Program (Environment) has similar approach, without funding for specific application development and testing.

Let’s Talk About Data
  • Existing Sources
    • States purchase information based on GPS probe data collected through cellular from private entities
    • Infrastructure Based Sensors providing data to management centers
  • V2V provides
    • Basic Safety Message Part 1
      • Core data elements communicated 10x per second via DSRC
    • Basic Safety Message Part 2
      • Additional data elements communicated via DSRC when an “event” happens
  • Mobility, Weather and AERIS Need What?

  • How often do you need them?
  • What are the benefits of the applications?
  • How do you get the data?
    • Installation of equipment?
    • Purchase from a data aggregator?
