Whats this all about?

• VII project is
• Defining a deployment strategy for VII
• Architecture
• Business models
• Policy / institutional issues
• Outreach
• VII will be the enabling communications
  infrastructure for new transportation services
• Other ITS Tier 1 Initiatives just described
• This project is discussing whether a full scale
  research and development project is warranted

3
Our objectives for this project

• What were doing .
• Discussing how VII data can be used in the near
  term to improve
• Arterial management
• Freeway management
• Corridor-wide transportation operations
• Identifying priorities for future research

4
The VII Paradigm Shift for transportation
management

• Greatly improved knowledge of travel patterns and
  traffic demand
• Accurate reliable information that causes
  travelers to modify their behavior (time, route
  and/or mode)
• Proactive traffic management strategies
• Adaptive traffic signal control
• Corridor-wide managed diversion

5
Development of a Research Plan

• Workshops were held to discuss the future of
  transportation management that is possible with
  VII
• Small group of knowledgeable and visionary public
  private sector experts participated
• Workshops held
• Arterial management focus in November 2004
• Freeway management focus in February 2005
• US DOT primed the pump with some proactive, and
  even provocative, ideas on how VII could help

6
Brainstorming Topics

• Traffic signal operations
• Arterial incident management
• Traveler information
• Corridor-wide operations

7
Results of the workshop New opportunities

• VII data will provide performance data that is
  not available today, particularly on arterials
• Improved transportation management systems will
  be possible with this new data
• Communication with drivers will be dramatically
  improved, with better information at the right
  place and time

8
Results of the Arterial workshop priority
research questions

• Can VII data be used with existing traffic
  control hardware / software?
• What new signal optimization strategies are
  possible with VII data?
• How do you address VII data requirements and data
  management issues?
• What new performance measures are possible with
  VII data?

9
Arterial workshop results (continued)

• Can VII eliminate the need for signal system
  detectors?
• Do all cars need VII?
• How can VII improve evacuation emergency
  planning and response?
• What types of information do travelers need to
  make decisions?

10
Results of the Freeway workshop priority
research questions

• Can we use VII data for predictive real-time
  operations for
• Incidents
• Crashes
• Recurring congestion
• Events
• Bad weather
• What quality and effectiveness (reflecting
  percent deployed) can we expect from the VII
  data?
• How can the VII data be organized into meaningful
  and accurate information that can be used for
  transportation management?

11
Whats next?

• We expect to develop
• Research plan for the next generation of
  transportation management that is enabled by VII
  data
