-
Security and Access Control: Physical barriers restrict access to authorized personnel or vehicles only. For high-security areas (government buildings, data centers, banks), they prevent unauthorized entry and protect against potential threats.
-
Traffic Management: Bollards and gates help control vehicle flow, ensuring that only intended vehicles can enter designated areas. This is particularly useful in pedestrian-heavy spaces, parking lots, or private drives.
-
Protection from Vehicular Attacks: In crowded public areas (e.g., parks, plazas), barriers protect against potential vehicle-based threats, either accidental or intentional, like ram-raiding or vehicle ramming attacks.
-
Pedestrian Safety: Physical barriers help separate pedestrians from vehicular traffic, reducing the likelihood of accidents and providing safe walking zones.
-
Property Protection: Barriers shield buildings, storefronts, and other property from accidental damage by vehicles. For instance, bollards in front of shops or sidewalks protect windows and facades from potential collisions.
-
Preventing Trespassing and Theft: In places like construction sites, private properties, or loading docks, physical barriers deter trespassers and potential thieves.
-
Aesthetic and Boundary Definition: Some barriers are also decorative, providing visual appeal while defining boundaries between areas, such as in parks or historical districts.

What is Hostile Vehicle Mitigation Barriers?
Hostile Vehicle Mitigation (HVM) barrier is a physical security device designed to prevent or mitigate the impact of deliberate vehicle attacks, such as ramming attacks or unauthorized vehicle access to secured areas. These barriers are engineered to stop vehicles from breaching perimeters by either halting or slowing them down. HVM barriers are used to protect high-risk sites, public spaces, critical infrastructure, and events from vehicle-borne threats.
