TRB Session 644: Using VII Data, Part 1
January 16, 2008
Powerpoint Version
The Critical Need for VII Agenda
-
Current state of traveler information
- What VII provides and enables
- Current VII activities related to traveler information
- Conclusion/next steps
Traveler Information Today - The Good
- Public sector progress
- 511 widely deployed
- 38% of freeway miles have detection (USDOT, 2006)
- 56% of fixed route buses with AVL (USDOT, 2006)
- Private sector progress
- New technologies for collection and dissemination
- Real time traffic and navigation more prominent
- Consumer interest is growing and prices are dropping
- Public-Private Partnerships are emerging
Traveler Information Today - The Bad
- Most metro areas still lacking quality traffic data
- High O&M costs effect reliability of public sector data
- As a result, data is not trusted
- Inadequate funding for O&M
- Real time data on arterials is almost non-existent
- New technologies are slow to be deployed
- Limited data/applications for other modes (e.g. transit, parking)
VII Can Revolutionize Traveler Information
- Complete network visibility (all roads, all modes)
- Data Collection
- low latency/real time
- high granularity and reliability
- Data Dissemination
- Brings data into the vehicle
- Can impact driver behavior en-route
- Can optimize network performance
Types of Data VII Can Provide
- Anonymous “probe” messages from vehicle to infrastructure
- Location, heading, speed, stop events, hard breaking events, weather conditions, vehicle diagnostics
- 2-5% penetration rate needed for accurate data
- Transit vehicles
- VII Advisory messages from infrastructure to vehicles
- En-route alerts, travel times, dynamic routing, hazard warnings (e.g. icy road), parking info, transit arrival times or delays
Types of Applications VII Can Enable
- Pre trip planning/routing for all modes
- En-route routing around incidents
- Transit arrival times, advisories and connection information
- “Killer Apps” from the private sector
- Off-board navigation using real time data on all roads
- Door-to-door driving times
- Real time map updates
- Parking availability/reservations
Current VII Activities for Traveler Information
- Michigan Development and Test Environment (DTE) and Data Use Analysis and Processing (DUAP)
- VII California Testbed
- New York ITS World Congress VII Demonstration
Michigan DTE and DUAP
- Michigan DTE supports testing of public and private sector traveler information applications
- DUAP project demonstrates public sector uses of VII data
- Incident detection
- Travel advisories
- Road and weather conditions
- Winter maintenance
- Asset management
VII California Testbed
- Leverages real world existing ITS for VII demonstrations
- Integration of existing data sources with VII probe data
- Complimentary uses of existing 511 system and VII
- VII tolling applications
- Congestion Initiative project will demonstrate additional VII applications
- Dynamic pricing
- Parking Information
- Transit information to buses (tentative)
New York ITS World Congress Demonstration and After
- Demonstrate numerous VII applications (including probe data collection, travel advisories, travel times, tolling, etc.) in Manhattan and Long Island
- Support for subsequent development of congestion-mitigation and road pricing related applications (post-World Congress)
Conclusion
- Current Traveler Information Systems are not adequately addressing the need for accurate, real time data on all roads and all modes
- VII provides a wealth of data that could revolutionize the traveler information industry
- VII enables numerous traveler information applications not currently available or mature
- Dynamic routing around incidents in real time
- Off-board navigation based on real time traffic conditions
- Door-to-door driving times with best alternative
- Multi-modal traveler information (transit arrival times and delays, parking availability/reservations)
Next Steps
- SafeTrip-21 and ITS World Congress Demonstration in 2008
- Monitor results of POC testing of traveler information applications
- Look for pre-VII early winners (e.g. I-95 Corridor Coalition probe data project)
- Leverage Congestion Initiative projects in New York and San Francisco
- Monitor cutting edge technology for VII and Traveler Information
