Liebert Case Study - 407 Express Toll Route


407 Express Toll Route


The 407 Express Toll Route (ETR), a 108 kilometer (67 mile) highway in Canada, is the world's first all-electronic, open access toll highway. Toll information is captured automatically through a Vehicle Detection and Classification (VDAC) system that reads signals from transponders installed in vehicles or by photographing license plates and issuing an invoice based on vehicle registration.

The Situation:

Enabling business continuity on the first all-electronic toll highway requires more than just a reliable source of backup power during outages. It also requires data center design that ensures sensitive electronics are receiving clean, conditioned uninterruptible power during regular operation and are isolated from extreme fluctuations.


  • Eliminated power problems that were occurring with previous uninterruptible power systems.
  • Survived extreme power fluctuations that occurred during the 2003 blackout with zero damage to expensive electronic systems.
  • Enabled consistent, accurate performance of critical revenue-generating electronics.
