Facility Selection Guide
What's the best way to accommodate bicyclists?
professionals and advocates don't always agree on the answer to
this common question. Is a bike lane better than a path or a wider
lane with no stripe? There is no simple answer and a lot depends
on the unique circumstances of a particular roadway in a particular
community. But, by reviewing more than 20 bicycle facility selection
guides from the US and other countries, consultant Michael King's
latest report for the PBIC suggests that there are indeed some
common ranges or parameters within which different bicycle facility
types seem to work best.
illustrated guide compares the thresholds of traffic volume and
speed at which agencies recommend providing different bicycle
facility types. On low-volume slow-speed roadways, no special
facilities are warranted for bicyclists. On high-speed, high-volume
roadways, a completely separate path for bicyclists might be desirable.
Almost everything in between requires engineering judgment and
this report helps guide the engineer or designer to some of the
factors to consider.
But the job
doesn't end there. Having determined the type of facility that
might be the most appropriate, the engineer or planner must then
use the best available planning tools and designinformation to
make sure the bike lane or trail can indeed fit in the space available,
handle all the intersections adequately etc. For that, you can
turn to the PBIC's planning, and
design and engineering pages.
