Current System

• Allows for basic AVL functions
• Serves as a tool for understanding AVL/GPS
  technology
• Provides a foundation on which we can continue to
  build on

23
Future Outlook

• Full integration of CAD system w/AVL system to
  allow for
• - Automatic route selection based on vehicle
  proximity to incident
• - In-vehicle navigation
• - Expansion of GIS base map to include
  attribute data layers

24
Future Outlook

• Full integration would entail
• - Install in-vehicle equipment for 50 fire
  vehicles
• - Develop communications interface between
  CAD AVL
• - Upgrade radio infrastructure
• - Establish new dispatch protocols

25
For Today...

• Complete system testing
• Benefit Assessment
• - Fire staff survey
• - ST staff survey
• - Examine all possible applications
• Seek funding for full build-out
