TTC Policy re: Speed Humps on TTC Routes

TTC Policy is as below:

  • Going over speed humps jostles bus passengers and could result in increased on-board injuries because bus passengers are not belted in, are often standing, and are not watching for sudden large bumps in the road;

  • Going over speed humps adds to customers’ discomfort and inconvenience and, as the transit system becomes more universally accessible to elderly, frail and disabled customers, this concern is accentuated;

  • Speed humps can result in undercarriage damage to buses with lowered ground-height clearances such as the low-floor vehicles now in the fleet; and

  • Repeated travel by buses over speed bumps could create an increased risk of structural and suspension fatigue-related failures that could not be consistently predicted and, therefore, would not be subject to preventive maintenance.

A message from the TTC:

The TTC is opposed to the installation of speed humps on any road on which we operate revenue service.  Given that the buses often operate with standing loads, the TTC see the installation of speed humps as creating an unacceptable risk to their customers.  And, it is for this reason that that authority for the installation of speed humps on roads on which TTC operates transit service rests with City Council. The TTC  believe there is only one road section with speed bumps on which TTC operates infrequent scheduled service; and these were installed prior to a formalization of TTC’s policy related to speed humps and were therefore grandfathered. TTC will request that they be removed once the road is scheduled for resurfacing.
