"TRAFFIC CALMING" MEASURES FOR OUR HUMAN LIMITATIONS
When we are faced with the limits of human cognitive capacity, it is
not enough to rely on the vigilance of individual road users.
Instead, we need to proactively design our roads, using “traffic
calming” infrastructure to shape driving behaviours and compensate for
human limitations.
The idea of traffic calming predates the invention of modern-day
vehicles. In the ancient city of Pompeii, archaeologists have found
evidence that raised crosswalks were installed to regulate traffic.
Today, traffic calming infrastructure continues to use the physical
design of roads to direct traffic flow. Most commonly, obstructions are
placed on roads to force drivers to slow down. This may involve measures
such as raising road segments with speed bumps or raised crosswalks,
implementing uneven surfaces or narrowing the road.
Studies have found that installing traffic calming features can slow
traffic by 20 to 80 per cent. In turn, these features have reduced
traffic injuries and deaths in cities around the world.
In the case of the River Valley accident, residents in the area have
appealed for more traffic calming measures for the neighbourhood. Those
who spoke to TODAY described a bend that creates a blind spot for
drivers going down the “steep” incline of Institution Hill and that
“there’s no proper crossing” for pedestrians.
In the case of the Taman Jurong accident, along Yuan Ching Road in
the vicinity of two schools, residents said it was more convenient to
jaywalk as the nearest traffic light crossings were “too far”.
GETTING SAFELY TO OUR DESTINATIONS
In light of the two recent traffic accidents, we need to pursue a multi-pronged approach to prevent the further loss of lives.
While we urge individuals to obey traffic laws, we must also empower
communities through traffic calming measures. This strategy combines
individual responsibility with systemic change, reflecting the different
causes of traffic accidents.
After all, road safety is no accident and should be a journey, not a final destination.
