  1. VII California: Investigating the Potential Benefits of VII ITS Michigan Annual Meeting May 24, 2005

  2. Convergence of Three Efforts • Expedited VII Project • VII California Program, for the ITS World Congress and beyond • Cooperative Intersection Collision Avoidance Systems (CICAS), California Style These efforts are slated to become the VII California Testbed

  3. Expedited VII Project

  4. Expedited VII Project: A Precursor to VII California Two roadside units (RSUs) on Interstate 80 • A combined Caltrans (Headquarters and District 4), PATH and DaimlerChrysler effort • Co-located with standard traffic data collection cabinets between Ashby and University Exits • Fits within standard model 334C cabinets, with model 170 controller • Cabinets part of Berkeley Highway Lab Initial, Simple Application Demonstrated • RSU broadcasts location of Ashby and University exits • If car detects an infrastructure-based query • Based on calculated distances, audio within car announces “exit ahead” • Countdown display in car every 50 meters until exit is passed

  5. Current Hardware Installation • PC104 computer running QNX6 real-time Operating System • Denso Wireless Access in Vehicular Environment (WAVE) Radio Module (WRM) • Currently no outside communication outside except WRM (no backhaul)

  6. 2. VII California Program

  7. VII California Goals • For the long term • Better manage the safety and productivity of the surface transportation system; • Benefit from the synergy of public sector, auto industry, and other private sector innovations; and • Build upon California’s already considerable existing infrastructure investments. • For the mid term • Provide a test-bed to investigate the technical feasibility and institutional value of VII. • Inform future decisions for the National VII Program; • Inform future decisions for California and Bay Area System Management Programs; and • Assess real world implementations of VII infrastructure, architecture and operations.

  8. VII California Goals CONT’D • For the World Congress • Demonstrate the capabilities of the emerging VII California test-bed: give notice that Caltrans, MTC and partners are committed to VII and will objectively investigate its potential; • Gain experience in VII and use case development and testing; and • Establish and give focus to the VII California public-private partnership.

  9. Potential Use Cases (Longer Term) • Vehicles as Traffic Probes • Vehicle Probes Provide Weather Data • In-Vehicle Signing • Travel Time Data to Vehicles • Incident Information to Vehicles • Work Zone Warning • Intersection Collision Warning • Intelligent Ramp Metering • Curve Overspeed Warning

  10. Potential Use Cases (World Congress) • Vehicles as Traffic Probes “511 for VII” • In-Vehicle Signing • Travel Time Data to Vehicles • Incident Information to Vehicles • Private OEM Application Other Potential Use Cases in Discussion

  11. Systems Engineering Design Process Concept of Operations Operations & Maintenance Assessment High Level Requirements System Verification Detailed Requirements High Level Design Subsystem Verification Detailed Design Integration & Test Implementation Time

  13. VII California / CICAS Test-bed Where is VII California? Bay Area IMS Map • Of 40 RSU, 20 will be on SR82: El Camino Real • Candidates for at least three CICAS Intersections 40 California VII RSU Locations (101, 280, SR 82)

  14. 3. CICAS, California Style

  15. Traffic Controller Cabinet Embedded Loop Detectors 60 Meters of 3M Microloops Signal Poles Radar Poles PATH RFS Test Intersection

  16. Vehicle-Intersection Wireless Testing – Current Status • Wireless infrastructure used to communicate between vehicles and intersection (DSRC) • DSRC test radios installed in vehicles and at intersection • Messages exchanged with approaching vehicle
