2. Deadly junction (pedestrian crossing
at large turning radius)
Tampines Ave. 9/ Street 45
Two young brothers, Nigel Yap, 13, and Donovan
Yap, 7, were killed by cement mixer.
Clementi Avenue 3/ Commonwealth Avenue West
Wife of a professor was killed by a Bus.
Woodlands Drive 63/ Woodlands Avenue 6
Boy hit by bus
*Most deadly: driver of Heavy Vehicles (HGVs) cannot
see pedestrian on their left while turning, regardless of
the speed they are driving.
3. Why these junctions can be deadly?
Blue car may hit crossing
pedestrian at high speed.
- blue car driver (A) need to clear the
junction, and enter the pedestrian
crossing as quickly as possible to
avoid collision with oncoming cars.
Red car may hit crossing
pedestrians
Large radius allows (some) drivers to
speed as they turn left.
Red car driver (B) need to watch out
the blue car (front, right direction)
while turning, easily miss the two
crossing pedestrian on the left.
In both cases, pedestrian may not
be aware of the threat because the
cars are coming from a direction out
of their vision.
4. Deadly junction (Driver need to have
180° vision to see the full picture)
Driver is distracted Pedestrian unaware of the danger
Consider the driver Consider the pedestrian
This image is captured by special wide angle lens.
Both driver and
pedestrian have
difficulty to check
each other at this
turning radius.
5. Inspiration from overseas
Compilation of ideas which make safe driving
and walking behaviour natural and easy at
traffic intersection and pedestrian crossing.
7. Tokyo, Japan (features that make
safe behaviour easy and natural)
(1) Red color lane
"Alert and slow down"
before entering pedestrian
zone.
(2) Protected lane
Railing separate
pedestrian from my path, I
can focus on my left where
pedestrian entering the
crossing.
(3) Double check
Driver and pedestrian are
within each other's view
before they enter into the
crossing area.
9. Kyoto, Japan
Pedestrian and
driver are
within each
other's view
Buffer zone to
slow traffic down
before entering
the pedestrian
crossing
"Protected" lane.
Allows driver to focus ahead
at the pedestrian crossing.
14. Learning points from other cities
Pedestrian crossing is a conflicting zone between powerful car and vulnerable
people. A "fail-safe" design is needed. Both road users must be able to check
each other, easily, before entering into the crossing area.
- position pedestrian crossing after the big round turn
- position pedestrian crossing perpendicular to traffic (fail safe design)
- one safety island for every two car lanes (easier, safer to cross)
- install speed hump before crossing to reduce car speed
- install speed regulating strips along the turning lane
(shift driver's foot from the accelerator to the brake pedal, make it natural and easy for
driver to stop the car in case of unexpected happens)
- consistent, dedicated safe crossing time (Green man = no car allowed)
Traffic intersection is a conflicting zone between cars from different directions.
Drivers need to take care of their own safety. Therefore,
- calm the traffic before entering intersection (lower the risk, easier to check)
- "protected" turning lane, allows driver to pay attention ahead to check crossing
pedestrian.
16. LoveCyclingSG who we are
● We are a group of normal people who love
cycling in Singapore (3600 members on FB)
● Many of us drive as well
● Riding our bicycles, we discovered there are
many opportunities to make the roads safer,
which benefits pedestrian, cyclist, & driver.
● Examples of our effort:
○ Open-map to identify hazard roads
○ Measuring lane width to identify opportunities
safer driving and safe space for cycling
○ Education on safe cycling practice during our rides
17. Land Transport includes walking &
cycling
● No car trip is completed without walking. At
the end of a car/bus/train trip, all of us need
to walk to the destination.
● Planning and designing for walking/cycling is
as important as planning for driving.
● We look to LTA to provide for the safe and
seamless movement of all Land Transport,
both motorized and non-motorized transport.
18. Three legged stool of Safe Roads
1.Road design
Reduce majority of
risky behaviour by
road design.
Make safe behaviour
natural and easy.
2. Education (Culture)
To clarify minor unclear situation
3. Law
Deal with remaining,
small number of
dangerous behaviour
with sufficient deterrence
Principal: Operator of dangerous
vehicles give way to vulnerable
users
1- road design, 2-education, 3-law
