511 Interoperability

1
511 Interoperability

• Report to the 511 Working Group
• April 2005

2
Task Force Goals

• The Interoperability Task Force has been working
  with two goals in mind
  
• Make using 511 easy for those who use multiple
  systems
  
• Make access to neighboring travel information
  systems seamless

3
Assess Current 511 Systems

• Surveyed current 511 deployers to determine
  common system attributes
  
• Information gathered on numerous categories
• User Interface
• System Content
• Types of Roads Covered
• Type of Data
• Awareness
• Main Menu Selections
• Connections to Other Systems

4
Interoperability Quick Tips

• A number of common elements were found, prompting
  the authoring of a Quick Tips document
  
• Certain items were targeted, such as a
  recommendation for recognition of a wider variety
  of grammars within menu selections.

5
Examples of Common/Alternative Grammars
6
Interoperability Recommendations

• Beyond grammars, the task force focused on the
  transfer of data and/or calls, as well as
  probably hybrid situations
  
• Discussions of common call transfer protocols
• Discussion of data transfer requirements, and
  database commonality issues
  
• Discussion of shared applications for 511 systems

7
User Interface

• All systems have Touchtone
• 22 plus 2 plan to use IVR
• 13 plus 2 plan to use text to speech
• 22 plus 1 plan to use concatenated
• 11 plus 5 plan to use Floodgates

8
Content

• All provide Roadway info
• 12 plus 2 plan to provide Transit
• 11 plus 1 plan to provide Tourism info

9
Roads Covered

• All cover Interstates and Us routes
• Most also have (some) State routes
• Few have Arterials
• None have real-time Transit

10
Type of Data

• All have Weather, Road Conditions, and Incidents
• 13 plus 1 plan to have Congestion
• 4 plus 5 plan to have Travel Times
• 5 plus 1 plan to have Transit Service
  Disruptions
  

11
Connections

• 13 plus 2 plan Transfer to Transit
• 8 plus 3 plan Call Transfer to 511
• 7 plus 1 plan Application Sharing
• 1 plus 4 plan Data Transfer

12
Conclusions (for now)

• National 511 Service Interoperability Vision
• 511 will be realized through locally deployed
  interoperable systems
  
• The ability to transfer calls between systems
  will be come as ubiquitous as the systems
  themselves
  
• By 2010, individual systems will be linked
  together into an integrated, seamless network
  
• This will be accomplished through the transfer of
  data over a common data structure or shared
  applications
