VII California: Investigating the Potential Benefits of VII

ITS Michigan Annual Meeting

May 24, 2005


Convergence of three efforts l.jpg
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



Expedited vii project a precursor to vii california l.jpg
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


Current hardware installation l.jpg
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)



Vii california goals l.jpg
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.


Vii california goals cont d l.jpg
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.


Potential use cases longer term l.jpg
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


Potential use cases world congress l.jpg
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

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)
