Mr Gerald Giam Yean Song asked the Minister for Transport 

a.     what percentage of pedestrian crossings have bollards of crash test standards such as the International Workshop Agreement (IWA) 14-1 or American Society for Testing and Materials (ASTM) F2656;

b.     of these, what percentage withstands the equivalent of (i) ASTM F2656 K4 (6,800 kg at 48 km/h) (ii) K8 (6,800 kg at 64 km/h) and (iii) K12 (6,800 kg at 80 km/h) respectively; and 

c.     what other specific quantitative standards are applied.

Reply by Senior Minister of State for Transport Dr Amy Khor:

1.     The bollards installed at pedestrian crossings by the Land Transport Authority (LTA) are not of the K4, K8 or K12 standards stated by the Member. Bollards of these standards are typically security bollards. They are installed at high security areas to protect critical infrastructure such as Changi Airport and Parliament House, and designed to be unyielding.

2.     The bollards that LTA has installed at around 100 signalised junctions are safety bollards that help protect pedestrians waiting to cross the road. They are designed to balance absorbing the impact from a vehicle and not causing serious injury to passengers in the vehicle.

3.     In contrast, as security bollards are designed to withstand high impact collisions without yielding, when a vehicle hits a security bollard, the vehicle will likely suffer severe damage and the passengers in the vehicle risk serious or even fatal injury.
