The applications of anti-crash bollards are diverse, extending beyond mere traffic control. In high-risk areas, such as the entrances of embassies or crowded marketplaces, these bollards act as a physical deterrent against potential terrorist attacks involving vehicles. By strategically placing them, urban planners can mitigate risks and protect their citizens from acts of violence. For instance, during public events where large crowds gather, temporary anti-crash bollards can be deployed to create secure perimeters and allow law enforcement to monitor the area more effectively.

Retractable belt queue bollards are space-efficient as they can be deployed only when necessary. Once the event or peak hours are over, they can be retracted, allowing for free movement and maximum utilization of space.
