1.Reliability: The fixed road bollards are designed to withstand high impacts. As such, when constructed, they can withstand the ramming of a truck and stop it before crossing over, keeping the pedestrians and other road users beyond them safe.
2.Cheap. Once installed, road bollards do not require any form of maintenance except maybe routine reflective paintwork. They, despite their significant roles, therefore, cost nothing to maintain.
3.Traffic calming: Bollards are well known to direct traffic to a particular direction. When erected, vehicles do not cross over them in the case of a traffic snarl-up to put at risk the other road users. As such, they act as a formal containment of traffic into the designated lanes even without the presence of traffic officers.
