Safety: pedestrian crossing at road junction (Singapore)
Traffic JunctionSafe Road for allSafety first, speed followsfeedback to LTADate shared with LTA (Road Safety and Road Engineering team): 2013-05-21Compiled by: Francis Chucontact: firstname.lastname@example.org
Deadly junction (pedestrian crossingat large turning radius)Tampines Ave. 9/ Street 45Two young brothers, Nigel Yap, 13, and DonovanYap, 7, were killed by cement mixer.Clementi Avenue 3/ Commonwealth Avenue WestWife of a professor was killed by a Bus.Woodlands Drive 63/ Woodlands Avenue 6Boy hit by bus*Most deadly: driver of Heavy Vehicles (HGVs) cannotsee pedestrian on their left while turning, regardless ofthe speed they are driving.
Why these junctions can be deadly?Blue car may hit crossingpedestrian at high speed.- blue car driver (A) need to clear thejunction, and enter the pedestriancrossing as quickly as possible toavoid collision with oncoming cars.Red car may hit crossingpedestriansLarge radius allows (some) drivers tospeed as they turn left.Red car driver (B) need to watch outthe blue car (front, right direction)while turning, easily miss the twocrossing pedestrian on the left.In both cases, pedestrian may notbe aware of the threat because thecars are coming from a direction outof their vision.
Deadly junction (Driver need to have180° vision to see the full picture)Driver is distracted Pedestrian unaware of the dangerConsider the driver Consider the pedestrianThis image is captured by special wide angle lens.Both driver andpedestrian havedifficulty to checkeach other at thisturning radius.
Inspiration from overseasCompilation of ideas which make safe drivingand walking behaviour natural and easy attraffic intersection and pedestrian crossing.
Tokyo, Japan (separate pedestriansfrom cars at big radius)
Tokyo, Japan (features that makesafe behaviour easy and natural)(1) Red color lane"Alert and slow down"before entering pedestrianzone.(2) Protected laneRailing separatepedestrian from my path, Ican focus on my left wherepedestrian entering thecrossing.(3) Double checkDriver and pedestrian arewithin each others viewbefore they enter into thecrossing area.
Learning points from other citiesPedestrian crossing is a conflicting zone between powerful car and vulnerablepeople. A "fail-safe" design is needed. Both road users must be able to checkeach 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 drivers foot from the accelerator to the brake pedal, make it natural and easy fordriver 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 crossingpedestrian.
LoveCyclingSG who we are● We are a group of normal people who lovecycling in Singapore (3600 members on FB)● Many of us drive as well● Riding our bicycles, we discovered there aremany 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 opportunitiessafer driving and safe space for cycling○ Education on safe cycling practice during our rides
Land Transport includes walking &cycling● No car trip is completed without walking. Atthe end of a car/bus/train trip, all of us needto walk to the destination.● Planning and designing for walking/cycling isas important as planning for driving.● We look to LTA to provide for the safe andseamless movement of all Land Transport,both motorized and non-motorized transport.
