Everyone benefits from a healthier diet: less fat & sugar,
more fruit & vegetables. But did you ever wonder what a better “diet” for
our roads would be? Given what we know about physical activity and human
health, and the pollution from cars & trucks, a healthier “road diet” would
include a greater proportion of pedestrians and cyclists sharing the road with
motor vehicles.
But just like eating better, healthier road use has
obstacles. Drivers often aren’t that good at sharing roads with cyclists or
pedestrians, and when the two collide, generally it’s the person on bike or
foot who suffers worse. As an occasional cyclist on Barrie’s streets, I notice
many motorists don’t understand the road rights of cyclists or how to safely
share, and when I drive, I even find myself unsure how much space to leave a
cyclist when I pass.
The simple answer is bike lanes: a clear definition of where
bikes and motor vehicles do or do not belong, a way to keep them safely
separate. They can share the road, without the more difficult feat of sharing
the same lane.
Yet city budgets have limited funds to widen roads to add
lanes, a process taking many years for planning, studies, approvals, funding
and finally, construction. Luckily, a much faster and more affordable approach
exists. Many of our roads are already wider than necessary for the smooth flow
of vehicular traffic, resembling speedways! By simply re-painting and
redefining lanes, we can create a better way for all road users to share and
maximize their benefit.
We can all share a road that's the right size. |
Called “rightsizing”, the most common example is when a
street with 4 car lanes (2 each way) is re-painted to 1 car lane in each
direction and a double-left turn lane in the middle. This leaves space to add a
bike lane to each side. Cities across North America are finding this an
effective way to reallocate street space to better serve the full range of
users.
Is this a “war on the car”? Far from it! With a 2-lane road,
you often have obstacles in one lane or the other – a person turning left, a
car parked in the right - which drivers weave back and forth to get around,
creating risk. By moving left-turners to their own lane and parking off the
main street, the remaining single lane allows smooth traffic flow, taking away
the weaving or “racing” between drivers in 2 parallel lanes. In this way, 3
lanes more safely handle nearly the same traffic volume as 4. Average speed
goes down a little while excessive speeding drops dramatically. This is the
traffic calming every neighbourhood needs, and it comes without the annoying
speed bumps or unnecessary stop signs between which hurried drivers “floor it”.
As a bonus, bikes can now travel, and be passed by cars, much
more safely. “Rightsized” roads also experience a dramatic drop in collisions,
good news for all road users.
And by making our roads more friendly and balanced, bicycle
and pedestrian traffic can gradually increase and our “road diet” improves. It’s
a win-win-win for driver, cyclist, and pedestrian with very little cost: just some
paint and new signage.
Longer-term transit plans include expensive rebuilding or
widening of many existing roads and new bike lanes will be part of that
process, but for now, “rightsizing” lets us get a head-start on expanding our
networks of active transportation without unduly penalizing the safe, steady
flow of car traffic.
