Introduction to IntelliDriveSM
• What is IntelliDriveSM?– Previously known as VII– Communication Infrastructure
• Vehicle-to-Vehicle (V2V)• Vehicle-to-Infrastructure (V2I)• Vehicle-to-Handheld Devices (V2D)
• What is the purpose of IntelliDriveSM?– Enable applications that provide safety, mobility,
commercial, and environmental benefits

1) DSRC equipped vehicle approaches CICAS-V intersection2) Vehicle receives local GPS correctionover DSRC. GPS position is corrected to ~ 0.5m accuracy allowing intersection approach matching3) Vehicle receives map (GeometricIntersection Description or GID) over DSRC4) Vehicle position mapped to intersection approach using GID

7) Warning algorithm determines that thevehicle cannot safely proceed based on thecurrent vehicle dynamics and the time to “red” phase.8) A warning is issued to the driver at the appropriate time.
5) Vehicle receives Signal Phase and Timing (SPaT)information over DSRC6) Vehicle warning algorithm Processes current vehicle dynamics information anddetermines if the vehicle can safely proceed through the intersection

Future of IntelliDriveSM-Deployment
• Phase I– 50% of signalized
intersections and all freeways in urban areas with 50% of population
– Every Interstate interchange
– 131,800 Roadside Units
• Phase II– 70% of signalized
intersections in 454 urban areas
– 10,000 units for smaller communities
– 14,000 on Interstates
– 239,000 Roadside Units
