- 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

- What it is
- Wi-fi radio product
- Adapted for high speed environment
- Cheap to produce in quantity
- How the technology works
- Messages transmitted at 10 times/sec
- Basic Safety Message (vehicle size, position, speed, heading
acceleration, brake system status)
- Operating range of 300 meters (line-of-sight)
- Benefits of the technology
- Reduced Price
- Less False Alarms à Delayed
warnings
- More Crash Scenarios à
Increased performance
- Can communicate “thru” other vehicles and blind intersections
- Drawback of the technology à Both vehicles need to be equipped

- 6 locations across the U.S. - began in August 2011
- Over100 drivers per location
- Experienced crash warnings
- Forward Crash Warning
- Emergency Brake Light
- Blind Spot Warning
- Lane Change Warning
- Intersection Assist
- Do Not Pass Warning
- Feedback from drivers was overwhelmingly positive
- ~90% of drivers expressed desire
for such a system
|

|
- Desirability
- 91% of drivers surveyed would like to have this technology on their
vehicles
- Willingness to Pay
- 58% of the drivers surveyed would pay more than $250 to have this
technology on their vehicles

|
- 3 Months of Data Collected
- Integrated light vehicles
- Light vehicle ASDs
- Heavy vehicles
- Data Transferred to IE
- Conducted preliminary analysis of system capabilities on dataset
- Data Transferred to Real-Time Data Capture Program
- Archiving data for industry research – Research Data Exchange
|
|
24
|
- Allowing additional time for end-to-end system testing
- Increased maturity level of device developers
- Identified ambiguous parts of specifications
- GPS antenna placement had a major impact on the performance
- Internal placement was not viable
- Viable external locations identified (truck, roof)
