Target Communication Networks
Vehicle To Vehicle Communication – Within 1/4 Mile
Vehicle to Driver to Vehicle Communication– Within 10 Feet
Vehicle to Infrastructure to Vehicle Comm. – Wide range / Multiple frequencies / Protocols
The “Smart Car” becomes the Center for Information Processing

Architectural Issues
U. O. Sept. 1999
Vehicle to Infrastructure to Vehicle
Congestion / Accident warnings Warning to plan stop at traffic light Construction / Detour warning with alternate
route Driving speed to pace traffic / signals Input Intended Destination and Get:
– Estimated travel times– Best Route
Weather conditions / hazards
U. O. Sept. 1999
Potential Vehicle-to-Vehicle Areas Information
Driver Characterization – Aggressive, Slow, Unskilled or Erratic (potentially impaired)
Vehicle Speed & Direction (Location)– Estimate left turn & passing clearances
Advanced Warning– Intended maneuvers from vehicles out of visual contact
Emergency situations– High deceleration, ABS or Traction Control actuation
Emergency vehicles in the area Cross traffic approaching too fast to stop
U. O. Sept. 1999
Vehicle to Driver
Multi-sensory feedback methods Prioritization of feedback (reduce
confusion and make faster decisions) Early warning of danger approaching Hands-free communication Eyes-on-the-road communication
U. O. Sept. 1999
Driver-to-Vehicle
“Smart Card” in pocket– Unlocks/opens doors / trunk– Identifies driver and accommodates seats, mirrors,
entertainment system, etc.– Notes medical information (in case of emergency)
Voice Recognition Hands-Free Communication Driving Habits Monitored & Characterized
– Better able to anticipate hazards / problems
