Working well

21

• Capturing data real-time and store-forward• On-line reporting tools and summaries• On-line tracking in real-time• Direct to 511 track my plow• Service provider archive in the cloud



Needs Work

22

• QA• Missing records• Cell drop outs• Sensor failure• Sensor accuracy

• Automation of tablet input reports• Distracted driving

• Client’s in-house archive• Input through firewall

• Road-user privacy with dashcams• Data retention interval, aggregation scale



AVL vs paper records

23

Extreme outliers removed• ESC or AVL not working• WOR missing records



Lesson Learned

24

• Operator buy-in• Supervisor/manager buy-in

• Prove accuracy• Reliable internet, new technology• Admit failures and have a backup

• AMC contractor buy-in• Achieve paperwork reduction

• Legal record



Conclusion
