Background

• 1957 – First State Driver Education Program

• 1967 – State Highway Safety Standards

• 1968 – Federal Motor Vehicle Safety Standards• 1978 – First Modern ABS System

• 1984 – National Minimum Drinking Age

• 1985 – First Vehicles Offer Anti-lock Brakes• 1989 – Passive Restraint System Required

• 1996 – First Graduated Driver Licensing System

We have hit a plateau…..

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

• Test of System’s Technical Feasibility– Can DSRC accommodate V2V and V2I…

• Detroit Test Environment– Robust and secure test environment– 75 center lane-miles– 52 DSRC RSE Units– Series of probe vehicles– Accommodates third party applications, a range of

OBE, and a variety of vehicle types– Enables real-time systems measurements

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

• Requires coordination between:– Government agencies– Auto manufacturers– OEM service providers– Public

• Potential User Benefits– Improved safety and mobility– Reduced environmental impacts– Auto and medical insurance benefits– New jobs– Engineering applications

17

How Long Will It All Take?Depends on: • Current light vehicle fleet

• New sales rates

• Market penetration

18

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
