VII - Vehicle
• GPS• Anonymous Probe Data – Speed,
Braking, Wipers, etc.• Vehicle-Vehicle and Vehicle-
Roadside Communication – Dedicated Short Range Communication (DSRC)
• Human Interface
DSRC
• FCC Licensed 75 MHz at 5.9 GHz
• Primary Purpose is Safety – Only Platform Meeting Latency Requirements
• Commercial Applications Allowed
• Standards– IEEE 802.11p– IEEE 1609 Family– SAE J2735 – Message Set
VII Infrastructure
• Road Side Equipment (RSE) – DSRC Radio, GPS, Processor, Router
• Backhaul Communication
• Service Delivery Node
• Certificate Authority - Security
• Network Management
VII Applications
• Public– Anonymous data
• Private– Secure transaction
Traveler Information
• Travel Times, Incident and Road Closure Warning, Work Zone Information
• Source of Data– VII Vehicles– Existing Systems
• Users– VII Vehicles– Dynamic Message Signs, 511, Media
Traffic Management
• Freeway Management Systems
• Arterial Management Systems
• Ramp Metering
• Area Wide Traffic Management
• Improved Planning Process
Weather Information
• Vehicle Data– Temperature– Traction Control– Wipers
• Users– VII Vehicles– Dynamic Message Signs, 511, Media– Winter Maintenance Operations
In-Vehicle Signing
• Static– Stop/Curve Ahead– Speed Limit– Guide Signing
• Dynamic– Traffic Stopped Ahead– Curve Warning– Real-Time Routing
Electronic Mapping
• Vehicle Probe Data
• Continuous Updates
• Lane level Accuracy
• Enables Safety Applications
Collision Avoidance
• Run Off the Road Warning
• Lane Changing Warning
• Stop Ahead Warning
• Signalized Intersection– Violation Warning– Timing Modification
Electronic Payment
• Tolling– National Interoperability
• Private– Fuel– Food
Current Activities
