What we Learned
¾
¾
¾
¾
¾
¾
AVL system design and deployment requires
interoperability across multiple systems
Look at as many major design alternatives as possible in
the early stages
Evaluate third party software/tools against the key
requirements, especially system level such as fail-over
scenarios, not just functional requirements
What we Learned
¾
¾
¾
¾
¾
¾
¾
¾
Get to know client environment prior to final deployment –
environment issues can be a problem
Stress testing before rollout is important for 24x7 mission
critical applications of this type
Need to think about scalability of solution to cover other
business areas
This is Cool Technology!
Future efforts

Currently looking at ASP model for vehicle data feed to
eliminate maintenance and administration of AVL backend
components
Looking to apply this technology to vehicles operating at
