VII California: A Convergence of Four Efforts

ATCE Forum Showcase

April 3, 2005

2

Four Efforts

1. Expedited VII

2. VII California for World Congress

3. Cooperative Intersection Collision Avoidance Systems (CICAS), California Style

4. World Congress Innovative Mobility Showcase (IMS)– Streets of San Francisco and SBC Park, too

These efforts are slated to become the VII California testbed

1. Expedited VII Laboratory(EVIIL)

Expedited VII: 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 control

cabinets between Ashby and University Exits• Fits within standard 332A cabinets, with

170 controller• Cabinets part of Berkeley Highway Lab

Initial Application Demonstrated– RSU broadcasts location of Ashby and

University exits– If car detects an infrastructure-based query

• Based on calculated distances, audio within car annunciates “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)

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 testbed to understand 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

• For the World Congress– Demonstrate and outreach emerging VII California

testbed: give notice that Caltrans, MTC and partners are committed to the concept and will objectively investigate its potential;

– Gain experience in VII and use case development and deployment; and

– Develop and give focus to the VII California public-private partnership.

Where is VII California?Bay Area IMS Map

40 California VII RSU Locations (101, 280, SR 82)

VII California / CICAS Testbed

• Of 40 RSU, 20 will be on SR82: El Camino Real

• Candidates for at least three CICAS Intersections

Potential Use Cases (World Congress)

1. Vehicles as Traffic Probes

“511 for VII”

2. Travel Time Data to Vehicles

3. Incident Information to Vehicles

Other Potential Use Cases in Discussion

4. Innovative Mobility Showcase

Streets of San Francisco

SBC Parking Lot B

12

Part A: The Streets of San Francisco

• Wireless connectivity– Circuit of

interconnected RSUs along a route encompassing Moscone Center and SBC Park, including including both city streets and freeways.

• Applications include: – Traffic probe data– Dynamic route

advisory– Intersection safety – Intermodal

connectivity

13

Part B: SBC Park Lot B

• Live vehicle demonstrations where attendees can “ride and drive” automobiles, trucks and buses fitted with ITS technologies in a controlled environment

• Applications include VII:– Intelligent

Intersection – Test Track Circuit

• Staging area with company booths

- Closed circuit TV to Moscone Center, providing a virtual experience to WC attendees.
