Burlington's "street print" at cross walks is too short (2m) to be
effective traffic calming for cars and trucks, which require a long hump
(4m) to make driving slowly more comfortable than fast driving. The
unfortunate side-effect of the crosswalk humps is that they are ideally
sized to make bike riding uncomfortable at road speed (speed
differential is often cited as a risk factor in crashes, so the improper
sizing of the humps may work against cyclist safety).
The central islands are very long and shallow (>10m), making it more
comfortable to drive on the center island. This tends to draw the alert
driver toward the center of the roadway. Apparently in response to this
island driving, the City has taken to putting lightweight bollards on
many of the islands.
Chapin claims that space and money limit traffic calming in Burlington.
This is not true. Lack of will and vision are the limiting factor.
Moguls, cushions, and Mini-roundabouts demonstrate that any type of
vertical traffic calming measure can be implemented within constrained
right-of-way. Replacing the Pine/Home stop signs and the Pine/Flynn
traffic signal with a mini-roundabouts using mostly textured, painted
asphalt would be good first step.
If the City is too timid to get serious about traffic calming there are
plenty of alternative solutions to the "Problem":
* Enforce the speed limit by police or automated photo-radar.
* Ban the use of jake brakes in Burlington.
* Relocate the bulk-break road salt depot out of the City. Instead of
burning cash on the Southern Connector, an efficient and profitable
intermodal port could be constructed at the end of I-189.
The City has plenty to learn about the fundamentals of traffic calming
and the engineering of proper road humps. But with the Filenes project,
the Main Street widening project, and the recent return to gutter
striping on North Willard Street, and lackluster traffic calming program
as evidence of Burlington's supposed commitment to cycling and walking,
it's clear that the City first needs to find the will to take cycling
and walking safety seriously and follow best engineering practices
rather than pursue political expediencies. I don't hold much hope for
