OPPORTUNITY FOR SAFER DRIVING
  • Greater situational awareness
    • Your vehicle can “see” nearby vehicles and knows roadway conditions you can’t see
    • 360 degree “visibility”
  • Reduce or even eliminate crashes thru:
    • Driver Advisories
    • Driver Warnings
    • Vehicle Control
4
RESEARCH TOWARDS IMPLEMENTATION
5
KEY SAFETY PROGRAM OBJECTIVES
  • 2013 Decision on Vehicle Communications for Safety (light vehicles)


  • 2014 Decision on Vehicle Communications for Safety (heavy vehicles)


  • 2015 Infrastructure Implementation Guidance


6
REMAINING RESEARCH IN SUPPORT OF 2013 DECISION
  • Interoperability à standards
    • Data
    • Communications
    • Security
  • Driver Clinics
    • User acceptance data
  • Model Deployment
    • Safety system effectiveness data
    • Real world operational proof
  • Device Certification
  • Policy Implementation Issues
7
Outstanding Technical Issues
  • Security
    • Establishing trust relationships
    • Credential management
  • Congestion mitigation
    • Ensuring messages arrive when they need to
8
The DSRC Technology for Safety
  • What it is
    • Wi-fi radio product adapted for high speed environment
    • Cheap to produce in quantity
  • How the technology works
    • Generates/receives messages at 10 times/sec
      • Basic Safety Message (vehicle size, position, speed, heading, acceleration, brake system status)
    • Operating range of 300 meters (line-of-sight)
    • Necessary for crash imminent situations
  • Benefits of the technology
    • Reduced Price
    • Less False Alarms à Delayed warnings
    • More Crash Scenarios à Increased performance
      • Can communicate around vehicles and blind intersections
  • Drawback of the technology
    • Both vehicles need to be equipped

SAFETY PILOT - TRYING TO DETERMINE…
  • User acceptance
  • Safety system effectiveness values
  • How the system operates in a real world, concentrated environment
    • Applications
    • Security
  • The role that aftermarket devices can play in accelerating benefits


  • Questions
    • Do aftermarket devices have the potential for accelerating benefits for safety?
    • If DSRC is mandated for safety, what is the growth potential for this enabling technology? Or is this anticipated to be a niche market for safety only?
11
SAFETY APPLICATIONS
  • Forward Collision Warning
  • Emergency Electronic Brake Light
  • Blind Spot/Lane Change Warning
  • Do Not Pass Warning
  • Intersection Movement Assist
  • Left Turn Assist



  • Curve Speed Warning
  • Red Light Violation Warning

FINALIZING THE V2V RESEARCH
SCALABILITY TESTING
  • Test with both static (red) and moving (green) vehicles
  • Multiple Scaling increments (50, 100, 200+ vehicles)
  • Employ congestion mitigation techniques
  • Integrate Security Solution

BASIC SAFETY MESSAGE (BSM) FUNDAMENTALS
  • Connected V2V safety applications are built around the BSM, which has two parts
    • BSM Part 1:
      • Contains the core data elements (vehicle size, position, speed, heading acceleration, brake system status)
      • Transmitted approximately 10 times per second
    • BSM Part 2:
      • Added to part 1 depending upon events (e.g., ABS activated)
      • Contains a variable set of data elements drawn from many optional data elements (availability by vehicle model varies)
      • Transmitted less frequently
    • No on-vehicle BSM storage of BSM data
    • The BSM is transmitted over DSRC (range ~1,000 meters)


  • The BSM is tailored for low latency, localized broadcast required by V2V safety applications
