Connected Vehicle Technology – 5.9 GHz DSRC
 What it is
□ Wi-Fi radio adapted for vehicle environment
□ Inexpensive to produce in quantity
□ Original FCC spectrum allocation in 1999
□ FCC revised allocation in 2004 and 2006
 How the technology works
□ Messages transmitted 10 times/sec (300m range – line of sight)
▪ Basic Safety Message: vehicle position, speed, heading, acceleration, size,
brake system status, etc.
▪ Privacy is protected (vehicle location is NOT recorded or tracked)
 Benefits of DSRC technology compared to radar/laser technology
□ Reduced price
□ Improved reliability  fewer false alarms
□ Increased performance  addresses more crash scenarios
 Drawbacks of the technology
□ Both vehicles need to be equipped to gain benefit
□ Requires security infrastructure

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
Connected vehicles have the potential to
address approximately 80% of vehicle
crash scenarios involving unimpaired
drivers

Connected Vehicle Applications
 Safety Applications
□ V2V
□ V2I
 Dynamic Mobility Applications
□ Traffic signal control
□ Flow optimization
□ Emergency response
□ Freight movement
□ Real-time options on all roads, transit, and
parking along your route
 Applications for the Environment Real-Time
Information Synthesis (AERIS)
 Road Weather Research

Enabling Technologies Role of Standards in Connected Vehicles
(Signal Phase and Timing Message)
Image Source: Thinkstock/USDOT
 Interface Standards are essential
 USDOT working with public and private
sector to define:
□ Communications standards for DSRC
□ Other media, e.g., 4G LTE and/or HD
radio may be used for appropriate
applications
□ Information Exchange Standards
▪ Message Sets for V2X
▪ Minimum performance
requirements for V2X messaging
▪ Signal controller messages
