Output vs' Outcome of ITS Performance in Florida

1
Output vs. Outcome of ITS Performance in
Florida
2
Principal Partners
3
Florida Transportation Commission

• No ITS performance measures
• Initiated request to ITS Florida in March 2003
• Now stressing outcome measures

4
Statewide Workshop

• October 2003
• National experts invited
• Over 50 Florida ITS professionals participated

5
Workshop Findings

• Performance measures must be aligned with program
  goals
• Difficult to isolate benefits derived from ITS
  deployment alone
• Development of ITS performance measures will be
  an on-going process
• As ITS proliferates, deployment service
  tracking (output) measures should evolve into
  measures of actual system performance (outcome)

6
Initial Performance Measures

• Number of 511 calls during times of incidents
• Number of Road Ranger responses during times of
  incidents
• Average incident response time
• Average incident clearance time
• Percent of actual vs. planned ITS deployment
• Travel time reliability for top-ten corridors
• Passenger-hours of delay (ITS vs. non-ITS)
• Percent of electronic by-passes at truck weigh
  stations
• Percent of electronic toll and transit payment
  transactions

7
Very Little Performance Data Exists!!
8
Parameters for Performance Measure Refinement

• Rely on existing data
• Should be easily understandable
• Involve all Districts, Central Office, and
  Turnpike Enterprise in the process
• Period of assessment will be April 2003-March 2004

9
Outcome Measures

• 170 miles managed by ITS
• (or 8 of limited-access FIHS)
• Over 310,000 annual Road
• Ranger stops
• Over 2.8 million annual 511 calls

Policy Logistical Issues

• ITS Program (quantitative) goals need to be
  formally established
• Base-line conditions need to be determined
• Detailed plan for collection of performance data
  must be developed
• Performance data collection must be accepted
  statewide, on-going/evolving, and adequately
  funded

Initial ITS Output Measuresvs.Ultimate ITS
Outcome Measures

• Travel Time Reliability
• Incident Timeline Documentation
• Customer Satisfaction Index

• Miles Managed
• By ITS
• Road Ranger Stops
• Number of 511 Calls

15
Subsequent Activities

• Report recommendations presented to FTC
  Performance Measures Working Group
• FTC Working Group chose NOT to include ITS
  chapter until outcome measures can be developed
• FDOT has taken action to ensure the development
  of ITS outcome measures are eminent
