Four Areas of Discussion - the Tip of the
Iceberg

• Web based distribution of public documents

  maintenance work within City roadways

  Internet to create a Virtual Ride

  train consultants, the general public, and staff

Web Based Distribution Genesis of our Program

• Process was already underway to scan 100,000
  construction plan sheets
• TDOT needed distribution platform that
• Didnt require individual software costs to
  deploy amongst all users
• Was easy to learn and use
• Built on existing regional technology
• Enhanced TDOT business
• Was capable of distributing LARGE amounts of data
• TDOT settled on Autodesks MapGuide platform 5
  years ago

Web Based Distribution What we have achieved

• 300 unique clients each day (65 of which are
  public clients)
• Surveyors, engineers, architects, planners,
  realtors, title people, news media, citizens
• Efficiency results of our system
• 80 reduction in ALL walk in clients seeking
  data
• Reduction of required customer service time has
  resulted in staff freed up to create more data
  for distribution!!
• Regional estimates indicate a 241
  savings/investment ratio
• One client recently stated, I do all of my
  research with your site. It is the best I have
  ever seen and, I do a lot of business!

Web Based Distribution What we have achieved

• 350 tons of pollutants per year are NOT entering
  our quality air in Tucson due to fewer physical
  trips to the offices

Geographic Display of Service Requests Example
of application for BOTH internal and external
customers

• Public request for work are digitized onto a
  map
• Service requests can be viewed on the TDOT
  MapGuide maps found at http//tdotmaps.transview.o
  rg
• Benefits to this application
• Easy tracking of Service Request(s) and
  anticipated completion dates
• Grouping of similar requests by maintenance
  crews for increased efficiency
• Elimination of duplicate requests
• Historical analysis of request data View Movie

The ARAN Van - Virtual RideSharing information
gathered for another purpose

• Automated Road Analyzer (ARAN)
• Van captures location (GPS), ride quality, and
  infrared data from roadway surface (every 25
  feet)
• Virtual Ride solution has offered the data to the
  public
• View Movie

Education TrainingHow we get people to know
what we have

• Pima County hosts quarterly classes
• Professional Society meetings, luncheons,
  seminars, etc.
• TDOT training for small groups (citizens,
  companies, staff)
• Actual use of mapping system at meetings
• Occasional news article
• Users are smarter today
• Greatest challenge is letting people know what
  data is available
