| FLEXIBLE BOLLARDS

SR-CITY-BALI was developed
especially for urban centers and it
reinforces separation and cohesion in
urban landscape design, improving
people’s urban experience as well as
increasing the safety and the ability
of pedestrians to walk freely in
urban centers.
These flexible bollards prevent
collisions by alerting drivers to offlimits
areas and encouraging safe
driving habits. The presence of SRCITY
BALI creates a visual barrier
that helps to direct and control traffic
by defining limits of space. If a
driver, a cyclist or a child riding an
e-scooter accidentally bumps into
one, they will feel gentle resistance
instead of a hard contact.
Made of a durable, rigid yet
flexible material, SR-CITY-BALI
is designed to fold down under
pressure so neither the vehicle nor
the bollard suffers damage and
human injuries are less severe. This
ensures long-lasting performance.
Reflective crystal tapes make them
highly visible by day and especially
at night.
Distraction techniques
With the new mobility paradigm
comes a lot of people looking at their
phones instead of paying attention
to their surroundings.
Distracted driving is a wellestablished
problem, but the problem
of distracted walking is a relatively
new one. Each year, more people
are injured and killed as a result of
using their phones while walking
or crossing the street.
SR-CITY-BALI-TL has been
developed to tackle this problem. The
light on the top of the bollard is
angled towards a pedestrian who is
looking at their phone. By connecting
with the pedestrian crossing traffic
lights, the LED on top of the bollard
changes from red to green according
to the traffic lights, alerting
pedestrians as to whether it is
safe to cross the street or not.
When it comes to vehicle collisions
that are the result of distracted
driving, the most effective harmreduction
measure is avoidance.
A simple sign should be enough to
discourage drivers from crossing a
line that they shouldn’t, but signs can
be missed and a clear physical cue
is more effective. Street bollards offer
close visual signals that reinforce
other traffic management strategies
to ensure the safest driver behaviors.
Considering the danger of steel
bollards and the need for something
that would stop cars without causing
unnecessary damage, Sernis
developed SR-BALI-LF. This larger
bollard is made with a more impact
resistant material and was developed
for use on highways, providing extra
visibility, protection and safety on
busy major roads.
The bollards can be used as part
of a wider traffic calming strategy,
encouraging safer, more responsible
driving. SR-BALI-LF helps guide
traffic into clearly delineated lanes,
and is an ideal non-impact barrier
solution because it does not damage
cars that hit them.
The bollards can withstand repeat
vehicle impacts without losing their
shape, which makes them ideal for
high-traffic areas where collisions
are frequent and expected. Bumping
into one will notify a driver who
has strayed from a lane without
interrupting the flow of traffic.
For example, its placement at
highway exit gore areas can
control traffic streams and
consequently reduce accidents.
Sernis flexible bollards are
designed and manufactured
in Portugal, ensuring product
quality and reliability. n
